San Francisco at night
Today’s Image of the Day comes thanks to the NASA Earth Observatory and features a look at the San Francisco area at night.
In the left of the photo is the city of San Francisco itself, with San Jose lighting up the sky just to the south. The two light spots to the east are the cities of Stockton and Modesto. The darker areas on the far right side of the image are the Sierra Nevada mountains.
This image was captured by an astronaut on board the International Space Station.
