NASA released these images of a smiling sun on Friday. Published by the Solar Dynamics Observatory scientists say the “eyes” are probably active sun regions and it’s mouth may be a solar filament. The dark spots we can see to the sides are coronal holes. NASA’s Solar Dynamics Observatory (SDO) is a spacecraft dedicated to studying these potentially dangerous variations, and the magnetic fields that drive them.
According to NASA Coronal holes are associated with ‘open’ magnetic fields and can be found at the sun’s poles. The Solar Dynamics Observatory is part of the NASA Living With a Star (LWS) Program, which was devised to understand causes of solar variability and the impact it has on our world. NASA launched the SDO in 2010 to study the nature of the Sun-Earth system and how it affects life on Earth.
The satellite beams 150 million bits of data per second about weather that originates within our sun. NASA released this video of images showing a smiling sun as shown above in video showing The new data from the Solar Dynamics Observatory won’t just help scientists trying to predict solar “weather,” like flares and coronal mass ejections, it should also help them better understand the sun. The mission’s high-speed, IMAX-quality photography will improve predictions of solar activity that can disrupt everything from GPS. SDO is designed to study the influence of the Sun on the Earth.
Today we are happy to see the sun smiling down at us.
