From bright planets to a mythological bird soaring among the stars, July 2025 has an exciting show lined up in the night sky.&nbsp;



NASA’s Jet Propulsion Laboratory (<a href="https://science.nasa.gov/skywatching/whats-up/">JPL</a>) has shared its skywatching highlights - revealing what to be on the lookout for this month, from sunset to sunrise.



<h2 class="wp-block-heading" id="h-planets-in-motion">Planets in motion</h2>



Venus reigns in the morning sky all month, shining brightly in the east during the hours before sunrise. Look for it near the Pleiades star cluster and two brilliant stars - Aldebaran and Capella.



<a href="https://www.earth.com/news/mars-lost-most-of-its-water-but-where-did-it-go/">Mars</a> is visible in the western sky shortly after sunset, glowing about 20 degrees above the horizon before it sets a couple of hours later. On July 28, it forms a striking pair with the crescent Moon.



Jupiter begins to climb into the morning sky after mid-month. Initially low on the eastern horizon, it rises higher each day, heading toward a dramatic August conjunction with Venus.



Mercury is visible only briefly - watch for it in the west during the first week of July, beginning about 30 to 45 minutes after sunset. It stays close to the horizon and sets quickly, so timing and a clear view are key.



<a href="https://www.earth.com/news/massive-energy-imbalance-discovered-on-saturn/">Saturn</a> makes its entrance around midnight and climbs high in the southern sky by dawn - offering a glimpse of the planet for early risers.

<h2 class="wp-block-heading" id="h-the-first-successful-mars-mission">The first successful Mars mission</h2>



July 2025 marks the 60th anniversary of NASA’s Mariner 4 mission, which performed the first successful Mars flyby in 1965. 



The spacecraft sent back the first close-up images of the Martian surface and revealed that the planet’s atmosphere was thin, cold, and not as Earth-like as once imagined.&nbsp;



Before Mariner 4, many scientists and the public still held out hope that Mars might resemble a second Earth - perhaps even supporting vegetation or signs of life.&nbsp;



However, the grainy black-and-white images, showing a cratered, barren landscape, were a sobering reality check that reshaped our understanding of the Red Planet.



Despite dashing earlier hopes, Mariner 4 paved the way for decades of <a href="https://www.earth.com/news/climate-collapse-why-did-mars-become-a-desert/">Mars</a> exploration. It was the first time humans had seen another planet up close. The mission proved that long-distance robotic exploration was not only possible, but essential.&nbsp;



<h2 class="wp-block-heading" id="h-spotting-aquila-in-the-july-sky">Spotting Aquila in the July sky</h2>



July is also the ideal time to view Aquila, the Eagle constellation, in the eastern sky during the first half of the night. Its brightest star, Altair, is easy to spot and forms part of the Summer Triangle, along with Vega and Deneb.



Aquila represents the eagle of Zeus in Greek mythology - a powerful messenger and symbol of divine strength. 



Altair marks the eagle’s heart, with its wings stretching wide across the night sky. To find it, look for the triangle-shaped pattern and note that Altair sits at the southern point.



While Aquila’s other stars aren’t as bright, they’re easier to trace under dark skies. The second half of July is especially good for observing this constellation, as the <a href="https://www.earth.com/news/how-did-earth-get-its-moon-a-new-theory-has-emerged/">Moon</a> rises later and leaves the early night sky darker.



For those in the Northern Hemisphere, Aquila is a summer favorite. Once you’ve located Altair, try to follow the eagle’s full wingspan across the sky. It appears to fly northward with its wings outstretched.



<h2 class="wp-block-heading" id="h-key-dates-for-july-skywatching-nbsp">Key dates for July skywatching&nbsp;</h2>



<ul class="wp-block-list">
<li>July 1–7: Mercury is bright and easy to spot in the west after sunset - if you catch it in time. It vanishes within an hour of sundown.</li>



<li>July 21–22: Look east before sunrise to see Venus and Jupiter joined by a crescent Moon, along with several bright stars.</li>



<li>July 28: In the evening sky, the Moon passes close to Mars, offering a beautiful pairing.</li>
</ul>



Whether you’re watching Mars fade into the west or spotting Venus and <a href="https://www.earth.com/news/jupiters-past-how-the-young-gas-giant-shaped-our-solar-system/">Jupiter</a> at dawn, July will be a rewarding month to keep an eye on the sky.&nbsp;

July 2025 skywatching: Bright planets and a summer constellation 

From bright planets to a mythological bird soaring among the stars, July 2025 has an exciting show lined up in the night sky.&nbsp; NASA’s Jet Propulsion Laboratory (JPL) has shared its skywatching highlights - revealing what to be on the lookout for this month, from sunset to sunrise.

Scientists use magnetic particles to improve the flavor of wine. A new study published by the <a href="https://www.acs.org/">American Chemical Society</a> describes how tiny magnetic particles can be used to improve the taste of wine. Using a magnetic treatment, a team of scientists successfully removed off-tasting substances in cabernet sauvignon without changing the wine’s desirable flavors and aromas. 

Wine contains naturally-occuring substances that contribute to its distinctive flavors. For example, alkyl methoxypyrazine (MP) compounds produce vegetable-like aromas in certain varieties of <a href="https://www.earth.com/news/weather-climate-impact-price-wine/">wine</a> such as cabernet sauvignon. 

In excess, however, MPs can overwhelm the fruity or floral aromas and throw off the balance of a wine's sensory characteristics. Such off-putting aromas and flavors often manifest in grapes that are grown in cool climates or harvested early.

There have been many unsuccessful attempts to disguise an unpleasant taste in wine by using additives such as activated charcoal or deodorized oak chips. 

A team led by David Jeffery at the <a href="https://www.adelaide.edu.au/">University of Adelaide</a> set out to explore an alternative solution by using polymers. The experts speculated that attaching magnetic nanoparticles to polymers would allow them to isolate and easily remove MPs from wine.

The researchers spiked cabernet sauvignon with a large amount of one particular MP, which produced a strong scent of green bell peppers, to test their theory. 

Using gas chromatography and mass spectrometry, the team found that magnetic polymers removed the compound from cabernet sauvignon more effectively than polylactic acid film. In addition, a group of taste testers reported that the wine's intense aroma had not been altered.

According to the researchers, this technique could help remove unwanted flavors from other wines as well.


The study was funded by the Australian Research Council's <a href="http://www.arc.gov.au/industrial-transformation-research-program">Industrial Transformation Research Program</a>.

The research is published in the <a href="https://pubs.acs.org/journal/jafcau">Journal of Agricultural and Food Chemistry</a>.

International team collaborates to improve earthquake prediction. Forecasting seismic activity is an important advantage for us humans, as it allows us to better prepare for an impending earthquake or volcanic eruption. But just how accurate are these forecasts? That’s the question the <a href="http://cseptesting.org/">Collaboratory for the Study of Earthquake Predictability</a> (CSEP) is looking to answer in an article published in <a href="https://pubs.geoscienceworld.org/srl">Seismological Research Letters</a>. 

Since 2007, CSEP has been analyzing <a href="https://www.earth.com/news/leaning-tower-pisa-earthquakes/">earthquake</a> forecast models to determine the accuracy of each model in predicting seismic activity compared to its competitors. CSEP has four testing centers in California, New Zealand, Europe and Japan – with a fifth being developed in China – where CSEP’s experiments and testing procedures have helped advance our knowledge of the predictability of earthquakes.International team collaborates to improve earthquake prediction

“The fundamental idea of CSEP is simple in principle but complex in practice: forecasting models should be tested against future observations to assess their performance, thereby ensuring an unbiased test of the forecasting power of a model,” explains Danijel Schorlemmer of <a href="https://www.gfz-potsdam.de/startseite/">GFZ Potsdam</a> in Germany. 

At each testing center, earthquake forecasts — produced automatically from a collection of models — are compared with the region’s actual observed seismic activity. These experiments are held to strict rules that involve a precise description of the region being studied and the seismic recordings themselves, among other stipulations. 

These experiments assess how well the number, distribution, and magnitudes of observed earthquakes in each region match up with each model’s forecasted prediction. For example, in Italy there are three CSEP experiments currently ongoing to assess one-day, three-month, and five-year earthquake forecasts for the country. According to the study’s authors, the one-day forecasts are accurate enough to have been incorporated into Italy’s Department of Civil Protection’s seismic forecasts.

CSEP has been conducting experiments since 2008, during which there were a number of major earthquakes. The 2011 magnitude 6.2 Christchurch quake and the 2016 magnitude 7.8 Kaikoura quake provided data used to refine real-time community warnings during these earthquakes.

Researchers have also used CSEP to test candidate seismicity models to be used in forecasting. This can help newer, more advanced models have their accuracy confirmed and determine whether they are worth using in the future. Ultimately, the experiments being done by CSEP could refine our ability to predict seismic activity, and help save lives in the process.

Bill Gates backs new system to absorb CO2 from the atmosphere. As you read this, vast amounts of <a href="https://www.earth.com/news/co2-emissions-cars-uk/">carbon dioxide</a> are being pumped into the air by industrial practices and the vehicles that fill up our roads. The contribution of this gas to climate change is significant, and it doesn’t seem to be halting anytime soon. But in a response to these emissions, <a href="http://carbonengineering.com/">Carbon Engineering</a> – a Canadian-based clean energy company – has outlined the design of a large industrial plant that is capable of capturing carbon dioxide from the atmosphere at a cost of $94 to $232 per ton.

Previous estimates for the cost of extracting greenhouse gases from the air were around $600 per ton, according to the <a href="https://www.aps.org/">American Physical Society</a>. This price point proposed by Carbon Engineering would be well below that.Bill Gates backs new system to absorb CO2 from the atmosphere 

“I hope to show that this as a viable energy industrial technology, not something that is a magic bullet ... but something that is completely doable,” says David Keith, a <a href="https://www.harvard.edu/">Harvard University</a> physics professor and founder of the company. 

Carbon Engineering has around 40 employees, and produces about a ton of carbon dioxide per day from their experimental plant. The company is owned by several private investors, including famous billionaire Bill Gates.

The technology for this project, outlined in the journal <a href="https://www.cell.com/joule/home">Joule</a>, makes synthetic fuels using only water, air, and renewable power. Keith believes that an industrial-scale plant would be able to make fuel at a dollar per liter, which would be competitive in California, where fuel prices are high due to the effort to reduce car pollution through low carbon fuel standards. An industrial plant could potentially capture a million tons of carbon dioxide per year, which is equivalent to the emissions of 250,000 cars.

Other experts commend the study as an advancement in clearing up major uncertainties about the costs of “direct air capture.” Reports from the United Nations suggest that governments may have to deploy similar technologies sometime this century in order to remove carbon from the atmosphere and bury it to limit global warming as part of the 2015 Paris climate agreement.

“Direct air capture is a politically promising route for carbon dioxide removal,” says Oliver Geden, of the <a href="https://www.swp-berlin.org/en/">German Institute for International and Security Affairs</a>. One of the many benefits is that an air capture plant could be built almost anywhere, as it would not impact farmland – unlike the planting of forests to take in carbon dioxide.

As we look to combat climate change in the future, these efforts will involve not only limiting our emissions, but finding ways to reverse the damage we’ve already done.

LED lights last longer, but some shades are harmful to wildlife. Noise and light pollution can be harmful to natural ecosystems, and studies have shown that human-caused <a href="https://www.earth.com/news/noise-pollution-reproduction-birds/">noise pollution can disrupt habitats</a> and even drive species decline. 

Now, a new study has found that certain shades of LED (light-emitting diode) outdoor lamps can also negatively impact wildlife, and researchers have created a database for consumers to know which LED colors are the least harmful.

The team determined that blue and white LED lights are the worst for animals while softer yellows, greens, and ambers are more benign. 

The study was conducted by a team of biologists from the <a href="https://www.usc.edu/">University of Southern California </a>and published in the journal Experimental Zoology Part A: Ecological and Interactive Physiology. 

LED lamps are popular and are expected to make up 69 percent of the global market by 2020. LEDs have many benefits including conserving energy and lasting longer than other traditional lights, however, these benefits can come at a cost to wildlife.

Previous studies have examined how light brightness and direction affects species’ migration, attraction, and circadian rhythms.

The researchers collected data from these light studies to help build a new database that developers, designers, and policymakers can use to choose wildlife-friendly LED lighting colors. 

“Outdoor environments are changing rapidly and in ways that can impact wildlife species," said Travis Longcore, lead author of the study. “We provide a method to assess the probable consequences of new light sources to keep up with the changing technology.”

For the study, the researchers focused on insects, sea turtles, salmon and the Newell’s shearwater seabird.

The researchers also found that sea turtles and insects are more vulnerable to bright LED lights at night. Sea turtles can follow the bright light inland after hatching instead of going to the sea. 

In order to reduce further species decline and help protect those species most vulnerable to LED light brightness, the researchers created the "Rapid Assessment of Lamp Spectrum to Quantify Ecological Effects of Light at Night,” a <a href="https://onlinelibrary.wiley.com/journal/19325231">database</a> that shows how two dozen different types of artificial lights impact animals. 

The hope is that city planner and policymakers will use the database to help pick the least disruptive and harmful light options for species. 

“If we don't provide advice and information to decision makers, they will go with the cheapest lighting or lighting that serves only one interest and does not balance other interests,” said Longcore. “We provide a method to assess the probable consequences of new light sources to keep up with the changing technology and wildlife concerns.”

Scientists underestimated how quickly oceans are losing oxygen. The world’s oceans are <a href="https://www.earth.com/news/ocean-deoxygenation-history-repeating/">losing oxygen</a>, but the technology to model this loss and project future rates of deoxygenation is insufficient, according to a new study. 

Recent research has found that the oceans have already lost two percent of their oxygen content worldwide in the past fifty years, and deoxygenation is expected to increase in the future. 

Now, a new study conducted by researchers from the <a href="https://www.geomar.de/en">GEOMAR Helmholtz Centre for Ocean Research Kiel</a> shows how current methods to measure deoxygenation and identify drivers of oxygen loss need improvement. 

The study was published in the journal Nature Geoscience, and the research shows why current models for deoxygenation are limited while also listing several drivers of oxygen loss that previous research had underestimated. 

“The comparison with our observation data reveals various inadequacies of the models and gives us indications in which direction we must concentrate our research efforts,” said Peter Brandt, the study’s co-author.

Global warming driver of ocean deoxygenation, but because there are so many different processes at work in the world’s oceans, it is difficult to accurately illustrate the full scope of how warming affects these different processes. 

“We often lack the data or the knowledge about many processes that interact in the ocean's response to global warming,” said Andreas Oschlies, the lead author of the study. “Our study shows that previous models significantly underestimate the effects of this interaction, at least on the oxygen distribution.”

One way that warmer temperatures affect ocean oxygenation is through oxygen solubility in the water. As the surface layers of the ocean warm up, fewer gases are able to be stored in the water. 

This process explains around 20 percent of deoxygenation in the ocean so far and models are able to efficiently represent solubility.  

However, models are less able to show how warmer temperatures affect the patterns of global ocean circulation which consists of both deep and shallow currents that supply oxygen to different layers of the ocean. 

“Many models have problems to describe this effect realistically because transport processes are often not resolved well enough or reproduced incorrectly,” said Lothar Stramma, a fellow co-author of the research. 

If climate change is a major driver of oxygen loss, it will impact both oxygen and carbon storage in the world’s oceans in the future. 

“We need multidisciplinary process studies to better understand the delicate balance of oxygenation and oxygen consumption in the ocean,” said Oschlies. “therefore, international initiatives such as the Global Ocean Oxygen Network are helpful. Oxygen is ideal for calibrating models that calculate the uptake of carbon dioxide by the ocean. So, at the same time, we would improve our knowledge of the carbon cycle.”

U.S. toddlers eat too much added sugar, and it could harm their health. Look at an average American toddler’s diet, and you’ll find added sugar, a new study found – sometimes more of the sweet stuff than even their parents should be eating.

A team of researchers led by Dr. Kirsten Herrick, an epidemiologist with the <a href="https://www.cdc.gov/">Centers for Disease Control and Prevention</a>, recently studied the diets of more than 800 toddlers between 6 and 23 months old. They found that 99 percent of them consumed more than 7 teaspoons of added sugar on an average day – about the same as a full-sized candy bar. 

"This is the first time we have looked at added sugar consumption among children less than 2 years old," Herrick said. "Our results show that added sugar consumption begins early in life and exceeds current recommendations.”

Another 60 percent of the children were getting extra sugar in their diet before they were a year old. 

The researchers got the data from the 2011-2014 <a href="https://www.cdc.gov/nchs/nhanes/index.htm">National Health and Nutrition Examination Survey</a>. In the survey, parents were asked to track everything their children ate in a 24-hour period. 

Researchers cataloged food items that contained extra cane sugar, high-fructose corn syrup, honey and other sugars. Artificial sweeteners with zero calories and natural sugars found in fruits, vegetables and milk weren’t included.

While the body processes natural and added sugars in the same way, added sugar raises concerns among nutritionists because it often replaces necessary nutrients in the diet. It has been linked to higher rates of obesity, high cholesterol, diabetes and high blood pressure, along with dental cavities.

Eating foods with these extra sugars as a young child can influence diet choices later in life, researchers said.

"The easiest way to reduce added sugars in your own diet and your kids' diet is to choose foods that you know don't have them, like fresh fruits and vegetables," Herrick said.

Vegetarian diet serves up a host of health benefits, research shows.  Bad news for meat lovers who want to eat healthier meals. A vegetarian diet – especially one that relies on high-quality foods – is linked to a host of health benefits, new research shows.

A collection of reports on the perks of a plant-based diet will be presented at Nutrition 2018, the first flagship meeting for the <a href="https://nutrition.org/">American Society for Nutrition</a>, held at the Hynes Convention Center in Boston from June 9 to 12. 

Among the posters, papers and presentations:
<ul>
 	<li>Getting protein from plants rather than animals is linked to a lower risk of coronary heart disease. A study of 6,000 people in the Netherlands over 13 years found that those who are more plant protein and avoided animal-derived protein had a lower risk of heart disease. Kim V.E. Braun of <a href="https://www.erasmusmc.nl/?lang=en">Erasmus University Medical Center</a> will share a poster presenting the study’s findings from 8 a.m. to 6 p.m. Sunday in the convention center auditorium. Vegetarian diet serves up a host of health benefits, research shows</li>
</ul>
&nbsp;
<ul>
 	<li>Choosing better-quality, plant-based foods is associated with a lower risk of death. Fang Fang Zheng of <a href="https://www.tufts.edu/">Tufts University</a> will present a study of nearly 30,000 U.S. adults that found the quality of the food people eat may affect the lifespan. Those who chose higher quality plant-based foods saw a 30-percent lower mortality rate, while quality of animal-derived food didn’t seem to affect mortality, the study found. The presentation will be held from 8 to 8:15 a.m. Monday in Room 311 of the convention center.</li>
</ul>
<ul>
 	<li>Eating a healthy, vegetarian diet is linked to healthy weight. A study of more than 125,000 adults over four years found that eating a plant-based diet made up of fruits, vegetables, whole grains and nuts was associated with less weight gain, according to Ambika Satija of the <a href="https://www.hsph.harvard.edu/">Harvard T. H. Chan School of Public Health</a>. Unhealthy plant-based foods, like fries and refined grains, were connected to weight gain, the study found. It will be presented from 4:45 to 5 p.m. Sunday in Room 209 of the convention center.</li>
</ul>
Other posters and presentations will share how a plant-based diet appeared to reduce the risk of heart disease and diabetes among South Asians living in the U.S., how vegetarian diets are associated with a lower risk of plaque in the arteries in a Brazilian study, and more.

The findings are preliminary, and the abstracts selected didn’t go through the same peer-review process that most scientific journals provide, the organizers noted. Still, the new research backs up dozens of similar studies in recent years. Over the past few months, studies have found vegetarian diets to be <a href="https://www.earth.com/news/vegetarian-diet-most-affordable/">healthy and affordable</a>, as well as <a href="https://www.earth.com/news/organic-diet-beneficial-environment/">better for the environment</a> – at least, when diners choose organic and whole foods rather than sweets and processed food items.

Founded in 1928, the American Society for Nutrition publishes four peer-reviewed journals each year, brings together nutritional researchers, medical professionals and other leaders, and provides education and professional development opportunities.

MIT engineers are recycling fresh water from power plants.  Engineers at the <a href="http://web.mit.edu/">Massachusetts Institute of Technology</a> (MIT) have developed a method that may be used to capture water as it evaporates from the cooling towers of power plants. The new system could lead to low-cost <a href="https://www.earth.com/news/cape-town-water-crisis/">water sources</a> in some regions that need them the most.

The cooling processes of electric power plants monopolize around 40 percent of all the freshwater from rivers, lakes, and reservoirs in the United States, and a lot of this water is lost as a vapor. The new technology from MIT has the potential to conserve some of this water and may even become an important source of clean drinking water for coastal regions that cool power plants with seawater.

By stimulating dense, foggy air with a beam of electrically charged particles, or ions, the water droplets also become electrically charged and can be controlled and collected.

The research team set out to develop highly efficient water recovery systems by capturing water droplets from both natural fog and the plumes of industrial cooling towers. 

In the plumes produced by power plant cooling towers, the stream of water vapor is much more concentrated than any naturally-occurring fog, which makes the system even more reliable. 

Furthermore, the process of capturing evaporated water is a form of distillation, so the resulting water is clean even if the cooling water is contaminated.

Study co-author Kripa Varanasi is an associate professor of Mechanical Engineering at MIT.

“It's distilled water, which is of higher quality, that's now just wasted,” said Professor Varanasi. “That's what we're trying to capture.”

According to the researchers, the recycled water could be used in processes that require pure water, such as in a power plant's boilers, or could be piped to a city's drinking water system.

Professor Varanasi explained that a typical 600-megawatt power plant could capture 150 million gallons of water a year. This represents not only millions of dollars in value, but also about 20 to 30 percent of the fresh water lost from cooling towers.

“This can be a great solution to address the global water crisis,” said Professor Varanasi. “It could offset the need for about 70 percent of new desalination plant installations in the next decade.”

Currently, the team is building a full-scale system to be tested on the cooling tower of MIT's Central Utility Plant, a natural-gas cogeneration power plant that provides electricity to most of the campus.

The research is published in the journal <a href="http://advances.sciencemag.org/">Science Advances</a>.

Scientists find a way to extract drinkable water from desert air.  In October of 2017, a team of researchers from the <a href="https://www.berkeley.edu/">University of California Berkeley</a> successfully extracted drinking water from the air using only solar power in the desert of Arizona. 

The experts have now applied their water extraction method on a larger scale with a next-generation harvester. The results of the recent investigation have revealed that the team's groundbreaking technique can be used in very low humidity conditions and at a low cost.


“There is nothing like this,” said Omar Yaghi, who invented the technology to develop the harvester. “It operates at ambient temperature with ambient sunlight, and with no additional energy input you can collect water in the desert. This laboratory-to-desert journey allowed us to really turn water harvesting from an interesting phenomenon into a science.”


The porous material that absorbs water is called a metal-organic framework, or MOF, and the researchers explained that the harvester can be easily scaled up by simply adding more MOF. 

But now, Yaghi has revealed that he has created a new MOF based on aluminum, called MOF-303, that is at least 150 times cheaper and captures twice as much water in lab tests. According to Yaghi, MOF-303 will enable a new generation of harvesters to produce over three cups of water per day from a single kilogram of MOF.

“There has been tremendous interest in commercializing this, and there are several startups already engaged in developing a commercial water-harvesting device,” said Yaghi. “The aluminum MOF is making this practical for water production, because it is cheap.”

Yaghi is working with King Abdul Aziz City for Science and Technology in Saudi Arabia, and its president, Prince Dr. Turki Saud Mohammad Al Saud, on the technology as part of their joint research <a href="https://globalscience.berkeley.edu/centers/KACST">Center of Excellence for Nanomaterials and Clean Energy</a>.

In the latest study by the UC Berkeley team, the researchers collected and measured the water and tested the latest-generation harvester under different humidity, temperature, and solar intensity conditions.

In their first experiment, the experts had predicted the harvester would be capable of working in low humidity conditions, and the findings of the new investigation have confirmed this theory.

“The key development here is that it operates at low humidity, because that is what it is in arid regions of the world,” said Yaghi. 

The harvester was found to collect water even at sub-zero dew points, making the water harvester ideal for people living in <a href="https://www.earth.com/news/end-great-american-desert/">dry regions</a> of the world that have little access to water.

The research is published in the journal <a href="http://advances.sciencemag.org/">Science Advances</a>.

This discovery means that not only are the “building blocks” of life present on Mars, but it’s clear that organic material can be preserved for billions of years on the planet’s surface.

The organic molecules were found in Gale Crater, which is believed to have once contained a shallow lake. Samples taken from two different drill sites on the lake bed have been found to contain complex organic molecules that look very similar to the fossilized building blocks of oil and gas on <a href="https://www.earth.com/news/moon-longer-days-earth/">Earth</a>. At this point, researchers are unable to determine whether this discovery come from life on Mars or from a less exciting geological process. However, “we’re in a really good position to move forward looking for signs of life,” says Jennifer Eigenbrode, NASA biogeochemist and lead author of the study published in the journal <a href="http://www.sciencemag.org/">Science</a>.

The Curiosity Rover is a $2.5 billion mobile chemistry lab that is powered by a nuclear battery and is roughly the size of a car. The rover has a 7-foot-long arm and contains 10 science instruments, 17 cameras, and a laser to “vaporize” rocks. Over the last six years, Curiosity has analyzed samples of soil and rocks for signs of organic matter, which is characterized by complex carbon chains that form the building blocks of life here on Earth.

The rover has also discovered traces of methane in Mars’ atmosphere, which researchers reported in an additional paper in Science. On Earth, most methane comes from biological sources, so this could be a significant finding as well.

“The detection of organic molecules and methane on Mar has far-ranging implications in light of potential past life on Mars,” explains Inge Loes ten Kate, a scientist at <a href="https://www.uu.nl/en">Utrecht University</a>. “Curiosity has shown that Gale Crater was habitable around 3.5 billion years ago, with conditions comparable to those on early Earth, where life evolved around that time.”

These findings are quite significant for us humans, as it brings us one step closer to knowing whether or not life has existed elsewhere in the universe. NASA’s Thomas Zurbuchen says, “with these new findings, Mars is telling us to stay the course and keep searching for evidence of life. I’m confident that our ongoing and planned missions will unlock even more breathtaking discoveries on the Red Planet.”

Bee brains can understand the concept of zero.  Basic bee brains can comprehend the concept of zero, according to a new study conducted by researchers from Australia and France.

The results, published in the journal Science, show that <a href="https://www.earth.com/news/bees-high-nectar-special-neurons/">bees</a> understand that nothing belongs at the lower end of the spectrum and could help with teaching Artificial Intelligence new tasks. 

Human brains have 86,000 million neurons but bees have <a href="https://www.earth.com/news/bees-high-nectar-special-neurons/">fewer than one million</a>.

It was thought that only humans, or species with similarly complex brains, could understand zero, which according to the researchers, is the backbone of modern mathematical and technological advancements. 

“Zero is a difficult concept to understand and a mathematical skill that doesn't come easily - it takes children a few years to learn,” said Adrian Dyer, a member of the research team. “We've long believed only humans had the intelligence to get the concept, but recent research has shown monkeys and birds have the brains for it as well. What we haven't known - until now - is whether insects can also understand zero.”

For the study, bees were presented with a series of images that contained different quantities of things. The bees were given a reward if they gravitated toward the image with the lowest number of elements. 

The bees would choose the image with two elements versus three and so on, and were given a sugar solution treat in return. 

Occasionally the researchers would show the bees a blank image, and even though they had not been trained to respond to an empty page or the concept of zero, the bees gravitated toward the picture with nothing. 

The fact that the bees went to the blank image shows that bees understood that nothing was lower than the other quantities shown, and the researchers say this provides a new understanding of how different brains grasp abstract concepts. 

“How does a brain represent nothing? Could bees and other animals that collect lots of food items, have evolved special neural mechanisms to enable the perception of zero?” Asked Dyer. “If bees can learn such a seemingly advanced maths skill that we don't even find in some ancient human cultures, perhaps this opens the door to considering the mechanism that allows animals and ourselves to understand the concept of nothing.”

The researchers are most excited about the implications the results could have for Artificial Intelligence and teaching relatively basic robots to operate in complex environments.

Engineers are pulling carbon out of the air to make gas and fuels. In the future, gasoline may originate from <a href="https://www.earth.com/news/carbon-capture-profitable-business/">carbon dioxide</a> pulled straight out of the sky rather than from oil pumped out of the ground. In fact, engineers at a facility in British Columbia are already successfully capturing carbon and turning it into fuel.

<a href="https://www.harvard.edu/">Harvard University</a> Professor David Keith is the founder and chief scientist of <a href="http://carbonengineering.com/">Carbon Engineering</a>, a Canadian CO2-capture and clean fuels enterprise.

“The carbon dioxide generated via direct air capture can be combined with sequestration for carbon removal, or it can enable the production of carbon-neutral hydrocarbons, which is a way to take low-cost carbon-free power sources like solar or wind and channel them into fuels that can be used to decarbonize the transportation sector,” explained Professor Keith.

Direct air capture technology uses giant fans to bring air into contact with an aqueous solution that strains out and traps carbon dioxide. Through heating and several chemical reactions, the filtered carbon dioxide is re-extracted and ready for further use, such as making valuable chemicals like fuels.


Professor Keith and his colleagues have implemented one of the first scalable and cost-effective working systems for direct air capture. 

The team has estimated that using their system on an impactful scale will cost roughly $94 to $232 per ton of carbon dioxide captured, which is drastically less than previous estimates of the cost of direct air capture that have ranged up to $1,000 per ton. 

“Electricity from solar and wind is intermittent; we can take this energy straight from big solar or wind installations at great sites where it's cheap and apply it to reclaim and recycle carbon dioxide into new fuel,” said Professor Keith. “Making fuels that are easy to store and transport eases the challenge of integrating renewables into the energy system.”


Hundreds of years of carbon emissions from human activities can provide an essentially unlimited stock of CO2 to be transformed into new fuels, including gasoline, diesel, and jet fuel.

“We are not going to run out of air anytime soon,” said Carbon Engineering CEO Steve Oldham. “We can keep collecting carbon dioxide with direct air capture, keep adding hydrogen generation and fuel synthesis, and keep reducing emissions through this <a href="http://carbonengineering.com/about-a2f/">AIR TO FUELSTM</a> pathway.”

The research is published in the journal <a href="https://www.cell.com/joule/home">Joule</a>.

Scientists are transforming chocolate into a functional food by infusing it with probiotics and prebiotics, aiming to create a treat that satisfies cravings while supporting gut health. 



The challenge lies in maintaining chocolate's beloved texture and flavor while adding health benefits.



<figure class="wp-block-embed aligncenter is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio"><div class="wp-block-embed__wrapper">
https://youtu.be/Ug657J67iEo?si=w96YjGMsg939LD_3
</div></figure>



Probiotics - beneficial microbes that balance gut bacteria and aid digestion - are typically fragile and can be destroyed by stomach acid or processing. 



Prebiotics act as food for these microbes, helping them thrive. Together, they form "synbiotics," a powerful health combination.



Researchers Smriti Gaur and Shubhi Singh from India's Jaypee Institute of Information Technology took an innovative approach, using natural prebiotics like corn and honey instead of complex processing methods. 



They created five chocolate varieties: a control and four synbiotic versions containing different combinations of prebiotics, probiotics (Lactobacillus strains), and flavor enhancers (cinnamon or orange).



Laboratory simulations of human digestion showed the probiotics remained viable for over five hours, suggesting they could survive long enough to benefit gut health.



Taste tests were positive, with researchers particularly enjoying the orange-flavored variety, describing it as having "vibrant citrus notes" complementing the "rich cocoa" with a "luxurious" texture.



This research represents just the beginning. With further refinement of strains, textures, and flavors, chocolate could evolve beyond mere indulgence to become a functional food that nourishes while it delights.



The study is published in the journal <a href="https://pubs.acs.org/doi/10.1021/acsfoodscitech.4c00741" target="_blank" rel="noreferrer noopener">ACS Food Science &amp; Technology</a>.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features Nushagak Bay, a large estuary in southwest Alaska. Nushagak runs mainly north to south and exits in Bristol Bay, a large body of water in the Bering Sea.



"The bay is primarily fed by the Nushagak River, which begins in the Alaska Range and flows southwest approximately 450 km. The bay is also fed by several additional rivers including the Wood, Igushik, Snake and Weary rivers," says ESA.



"The dark colors of the Nushagak River are most likely due to tannins or lignins (chemical substances found in plants). Tannins and lignins from roots, leaves, seeds, bark and soil can leach into the water and give it a brown or even black colour. The sediments then flow southwards where it is mixed with the bluer waters of the bay."

Today's Video of the Day from the <a href="https://www.acs.org/">American Chemical Society</a> (ACS) reveals that proteins on flu viruses are actually flexible, tilting and waving in a “breath-like” motion. According to the experts, these proteins could be used to better defend against the flu.



"The main antigenic targets of influenza virus are two surface glycoproteins, hemagglutinin (HA) and neuraminidase (NA). Whereas the structural and dynamical properties of both glycoproteins have been studied previously, the understanding of their plasticity in the whole-virion context is fragmented," wrote the researchers.



To investigate, the team conducted detailed simulations of the influenza A H1N1 virion, or the swine flu. The experts concluded that the visualizations show many new vulnerable states of flu viruses, which could improve future vaccines and antiviral drugs.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features Lake Trasimeno, which is located west of Perugia in central Italy. It is the fourth largest lake in the country. While Trasimeno’s water level varies, it has a maximum depth of approximately six meters.&nbsp;



"In this Copernicus Sentinel-2 image, captured on 6 August 2022, the lake’s emerald green colour is likely due to the presence of phytoplankton. Streaks in the water, particularly visible in the west, indicate the presence of soil and sediments which have been stirred up by winds. Dark colored waters in the southern part of the lake indicate a presence of submerged and floating macrophytes (aquatic plants) as well as algae," says ESA.



"Surrounded by hills on three sides, Trasimeno is subject to heavy storms created by winds, especially from the north and west. There are three islets in the lake: Maggiore, Minore and Polvese (the largest). The lake’s shores are sparsely inhabited with only two popular villages: Castiglione del Lago and Passignano sul Trasimeno."



"Italy is experiencing its worst drought in 70 years which has affected drinking water supplies, hydroelectric power and agricultural production. High temperatures, hot winds and lack of rainfall are the main causes of drought in the Umbrian region which saw Lake Trasimeno’s drop 1.3 m, reaching the limit of the hydrometric zero in July 2022."

The oxidized form of mercury can be harmful when it is ingested through contaminated water or food. This makes it necessary for experts to develop sensors that can quickly and accurately detect the presence of mercury.&nbsp;



Zong-Hong Lin and colleagues have now created a triboelectric nanosensor (TENS) that can detect mercury by simply by touching a sample. According to the researchers, their TENS could serve as the basis for similar devices to safely and remotely monitor other pollutants.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features Kainji Lake, a reservoir on the Niger River.



In 1968, Kainji Lake was created by the construction of the Kainji Dam. The Niger River, the third longest in Africa, enters the lake in the north.&nbsp;



According to <a href="https://www.earth.com/news/rivers-in-the-american-west-are-a-lifesaving-resource-for-birds/">ESA</a>, the creation of the lake submerged Foge Island and the town of Bussa and permanently flooded other riverine settlements, leaving around 50,000 people displaced.&nbsp;



Large parts of Foge Island are temporarily exposed during low water tides, and the land is often used by migrating fishermen. Kainji Dam is a dam across the Niger River in Niger State of Central Nigeria. 



Wild mammals occur at relatively low densities due to illegal hunting. Lake Kainji has suffered a dramatic decline as a fishery due to the high numbers of artisanal and subsistence fisherfolk using the lake. It has been suggested that a period of closure, together with controlled fishing rights may help improve fish stocks.



Kainji Lake National Park is the oldest of its kind in Nigeria. The park contains three distinct areas: a part of the Kainji Lake, the Borgu Game Reserve to the west of the lake, and the Zugurma Game Reserve to the southeast. The park is home to around 65 mammal species, 350 bird species, and 30 species of reptiles and amphibians.

Today’s Video of the Day from <a href="https://www.igb.illinois.edu/">Carl R. Woese Institute for Genomic Biology</a> reveals how scientists can modify common crops like soybean, rice, and wheat to protect them from heat stress.



“We need to double crop production by 2050 to feed a growing global population, and not only are we not on track to do that, but climate change is further complicating things,” said Amanda Cavanagh, a lecturer at the University of Essex. 



The study is part of Realizing Increased Photosynthetic Efficiency (RIPE), an international research project that aims to develop food crops that turn the sun’s energy into food more efficiently.



“Using an engineering approach we designed multiple alternative metabolic pathways to photorespiration. Testing them in the field showed increases in productivity which led Amanda to significantly move the project forward by showing our engineered plants can withstand pretty extreme temperature stress,” said study co-author and RIPE researcher Paul South.&nbsp;



“As the climate changes and temperature stresses increase the pressure on our global food supply, farmers will need every tool available including engineering approaches like the synthetic biology used here to maintain safe and productive harvests.”



The experts tested plants modified to have more efficient photorespiration to see if they were better adapted to warmer temperatures.&nbsp;



The team found that the engineered plants produced 26 percent more biomass than the wild-type plants exposed to the same temperatures, and had 15 percent less yield loss under the higher temperatures.

Today’s Video of the Day from the <a href="https://www.acs.org/">American Chemical Society</a> explores the ability of salt to transform the way that foods and beverages taste. Salt is known to cover up undesirable flavors, such as bitterness in coffee or beer, but how exactly does sodium chloride change the taste of other compounds?



One previous study showed that, not only does salt suppress bitterness, but also enhances sweetness and sourness. Another study revealed that bitterness reduction by salt seems to be happening at the tongue receptor level as well as in the brain.&nbsp;



While it is known that salt taste is mediated by the presence of sodium channels in the form of taste buds, experts believe that there is also an unknown receptor responsible for how we taste salt that has not yet been identified.&nbsp;

'The weather of Santiago resembles the Mediterranean climate with dry and warm summers with temperatures reaching up to 35°C (from October to March) and cool and humid winters that can drop to 0°C (from April to September)."



"The city lies in the centre of the country’s central valley around 80 km from the Pacific Ocean to the west and borders Argentina to the east. A tiny part of Argentina is visible in the top-right corner of the image where the mountain crest of the Andes Mountains acts as a divider between the two countries," says ESA.

Astronomers at <a href="https://www.jhu.edu/">Johns Hopkins University</a> have created an interactive map of the universe, including the actual position and real colors of 200,000 galaxies. The map allows the public to access data that was previously only available to scientists.



The map was developed using data collected by the Sloan Digital Sky Survey. For over two decades, a telescope in New Mexico was aimed at slightly different locations to capture the night sky.&nbsp;



"Growing up I was very inspired by astronomy pictures, stars, nebulae and galaxies, and now it's our time to create a new type of picture to inspire people," said map creator Brice Ménard, a professor at Johns Hopkins. "Astrophysicists around the world have been analyzing this data for years, leading to thousands of scientific papers and discoveries. But nobody took the time to create a map that is beautiful, scientifically accurate, and accessible to people who are not scientists. Our goal here is to show everybody what the universe really looks like."



"In this map, we are just a speck at the very bottom, just one pixel. And when I say we, I mean our galaxy, the Milky Way which has billions of stars and planets. We are used to seeing astronomical pictures showing one galaxy here, one galaxy there or perhaps a group of galaxies. But what this map shows is a very, very different scale."



"From this speck at the bottom, we are able to map out galaxies across the entire universe, and that says something about the power of science."



The <a href="https://mapoftheuniverse.net/">interactive map</a> is available online, where it can be downloaded for free.

Today's Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> describes the first comprehensive estimate of carbon density in the Saharan, Sahel, and Sudanian zones of Africa. In an effort to measure the amount of carbon stored across these drylands, a team of scientists used high-resolution satellite images and artificial intelligence to map nearly 10 billion individual trees. 



"The high spatial resolution (50 cm) combined with AI and field measurements used in this study is key to improving tree inventories in drylands," said Pierre Hiernaux, a French researcher working for NASA. "The ever-increasing availability of very high-resolution satellite imagery will make it possible to assess carbon pools and their dynamics at the individual tree level on a global scale."



"This study is exceptional because it is pioneering a type of approach that will revolutionize the monitoring of trees and forests on a global scale: in the short term, it will be possible to map the world's trees from the centre of the Amazon to our schoolyards," said <a href="https://www.inrae.fr/en">INRAE</a> researcher Jean-Pierre Wigneron.



"Many fields of application will become much more efficient and accurate, such as tracking carbon stocks, biodiversity, monitoring logging and protection against illegal forest degradation, in near real time.”

Today's Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features Dublin, the capital and largest city of Ireland. Beyond its pub culture, Dublin is known as a modern culinary destination and a UNESCO City of Literature.



"Dublin is located near the midpoint of Ireland’s east coast in the province of Leinster. The city, which covers an area of around 115 square kilometers, is bordered by the Dublin Mountains, a low mountain range to the south, and is surrounded by flat farmland to the north and west," says ESA.



"The city straddles the River Liffey, which rises in the Wicklow Mountains and flows around 80 kilometers eastwards through the city of Dublin, in which it is canalised and bordered with quays. It then empties into Dublin Bay, an arm of the Irish Sea."



Dublin has an abundance of green spaces, including one of the largest enclosed public parks in any European capital city. Phoenix Park, which was originally formed as a royal hunting park in the 1660s, includes 707 hectares of green space.

Today's Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features the province of Zaragoza in northeast Spain. The image was captured by the Copernicus Sentinel-2 mission.



"Together with the provinces of Huesca and Teruel, Zaragoza formed the old kingdom of Aragon. Its capital, also called Zaragoza (not visible in this image) is home to around half of Aragon’s population," says ESA.



"The Ebro River can be seen winding its way through the province from west to east in this image. Between its source in the Cantabrian Mountains in the northwest and its delta on the Mediterranean coast, the Ebro River is fed by more than 200 tributaries as it flows 910 km across much of northern Spain."



Since rainfall is very scarce in this region, irrigation in the Ebro basin is critically important. In the valleys surrounding the Ebro River, many fields are used for growing crops such as corn, wheat, and barley.

Today's Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> features a visual dataset of.methane emissions from wetlands across the globe. Atmospheric methane levels have reached record highs in recent years, and wetlands are a major source of these emissions.&nbsp;



"Methane is an important greenhouse gas that contributes substantially to global warming. On a molecule by molecule basis, methane is much more efficient at trapping heat than carbon dioxide, the main driver of warming," says NASA.



"Though human activities, including agriculture, oil and natural gas production and use, and waste disposal, collectively contribute the majority of methane to the atmosphere, about a third of total methane emissions comes from wetlands."&nbsp;



According to NASA, understanding methane emissions from wetlands and other natural sources is critically important for scientists and policymakers who are working to combat climate change by reducing emissions from human activities.

Today’s Video of the Day from <a href="https://earthobservatory.nasa.gov/">NASA Earth Observatory</a> reveals the evolution of the Columbia Glacier in southeastern Alaska. Columbia is among the fastest shrinking glaciers in the world, and the video documents its rapid retreat over the years.&nbsp;



Columbia Glacier is a large, multi-branched calving glacier that flows out of the Chugach Mountains to the Prince William Sound.&nbsp;



According to USGS, Columbia had a long history of stability prior to 1980, with a length 41 miles, and small, short-lived advances or retreats.



In the years since 1980, however, satellite images have captured Columbia’s alarming retreat. By using false-color images, scientists can distinguish between snow and ice, open water, vegetation, and rocky debris on the glacier’s surface.



The series of false-color images featured in today's video were acquired over the span of 35 years. You can see that by 2021, the glacier’s main branch had retreated about 15 miles from its initial position.



The Columbia Glacier has also lost more than 50 percent of its volume, mostly due to calving. <a href="https://www.earth.com/video/nasa-reveals-3d-visual-of-an-atmospheric-river/">NASA</a> reports that while climate change likely started the retreat, mechanical processes kept the disintegration going.



The NASA images are provided by Jesse Allen, Robert Simmon, Joshua Stevens, and Lauren Dauphin using data from Landsat satellites, from the U.S. Geological Survey, and data from MODIS on NASA’s Terra satellite. The structure of Columbia’s moraine played a large role in the stability of the glacier before 1980. 



Like other tidewater glaciers, the Columbia built up a moraine over time, and the mixture of ice and rock functioned like a dam keeping out the sea. It was supported on one end by the shoreline and by the underwater terminal moraine at the other.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features the Pyrenees Mountains, which form a natural boundary between France and Spain in southwest Europe.



The mountain range is 430 kilometers in length. It stretches from the Mediterranean Sea on the east to the Atlantic Ocean on the west.



At an elevation of 3404 meters, Pico de Aneto is the highest mountain peak in the Pyrenees, and the third-highest peak in Spain. Pico de Aneto is located in the Posets-Maladeta Natural Park, which spans more than 82,000 acres.&nbsp;



"Geological studies have revealed that the Pyrenees Mountains have been around for longer than the Alps, with their sediments first deposited in coastal basins during the Paleozoic and Mesozoic eras," reports ESA.



"The entire mountain range formed due to the upwelling of large sedimentary rocks by the collision of the Iberian and the Eurasian plate around 100 to 150 million years ago, followed by intense erosion from ice and water."



The western Pyrenees receive more precipitation due to moisture blowing in from the Atlantic Ocean. The mountain range contains many lakes, several small glaciers, and some of the highest waterfalls in Europe.

Today’s Video of the Day from <a href="https://www.stowers.org/">Stowers Institute for Medical Research</a> describes why experts are studying zebrafish to gain a better understanding of how the immune system responds to injury. Zebrafish have the ability to repair and regenerate organs.



“Organ regeneration offers an exciting opportunity for studying the immune system and to inquire why some species can regenerate organs like the heart or missing limbs while others like humans cannot,” explained Dr. Tatjana Piotrowski.



Zebrafish sensory organ hair cells are an ideal system to investigate the pathways and cell types involved in regeneration since they are easily destroyed with antibiotics and begin regenerating within five hours. This enabled the researchers to identify the exact timing and genetic programs for each anti-inflammatory macrophage activation state.&nbsp;



“Our hypothesis is that human macrophages do not receive the proper chemical activation 'cocktail' to instruct pro-regenerative processes,” said Dr. Nicolas Denans. “Identifying the molecular recipe of macrophage activation in zebrafish may one day enable us to design regenerative immunotherapies in humans.”&nbsp;&nbsp;&nbsp;



“The new evidence is a valuable resource for comparative studies on the genetic programs involved in macrophage-mediated repair and regeneration. In other words, different types of injuries may induce different kinds of inflammatory responses. We want to decipher whether this 'language' is universal or if there are a variety of dialects."

Today's Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> describes how record-breaking heat expressed itself around the world in 2022.



Scientists have determined that 2022 was the 5th warmest year since 1880. Furthermore, the last nine consecutive years have been the warmest on record.



From devastating floods and wildfires to natural disasters like Hurricane Ian, 2022 showed us yet again how a warming climate affects people across the globe.&nbsp;



"As we look back at 20:22 and years past, we see that each year we better understand the challenges we face and how important it is to meet them," says NASA.

Today's Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> describes two exoplanets that are orbiting a star 218 light-years away. A team of researchers led by the University of Montreal has found evidence that these planets are "water worlds."



The experts used data from NASA’s Hubble and Spitzer Space Telescopes. They discovered that exoplanets Kepler-138 c and Kepler-138 could be composed largely of water.



"We previously thought that planets that were a bit larger than Earth were big balls of metal and rock, like scaled-up versions of Earth, and that's why we called them super-Earths," explained study co-author Björn Benneke.&nbsp;



"However, we have now shown that these two planets, Kepler-138 c and d, are quite different in nature and that a big fraction of their entire volume is likely composed of water. It is the best evidence yet for water worlds, a type of planet that was theorized by astronomers to exist for a long time."

Satellites reveal how Earth's systems are interconnected Today’s Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> describes Earth’s interconnected systems, and how this network is affected by rising temperatures.&nbsp;



During 2020, average global temperatures matched the hottest year on record. The hurricane season was also record-breaking, with many of the storms intensifying at extraordinary speeds. Hot water in the ocean is fuel for hurricanes. The satellite data shows that it's all one interconnected system showing how Satellites reveal how Earth's systems are interconnected.



According to NASA, dust swept up from Northern Africa plays a major role in the formation of hurricanes, and is also a key source of fertilization in the Amazon rainforest. As a result of<a href="https://www.earth.com/news/seagrass-wasting-disease-is-fueled-by-climate-change/"> climate</a> change, dust plumes are expected to decline, which will have an effect on vegetation far away.&nbsp;



Images from Earth-observing satellites show how the world’s plant life is affected by natural disasters, fires, and deforestation. Satellites also reveal how widespread changes in vegetation impact waterways,&nbsp; the climate, air quality. Satellites communicate by using radio waves to send signals to the antennas on the Earth. "Earth From Space" is a groundbreaking two-hour special that reveals a spectacular new space-based vision of our planet.
