Great Dark Spot
This image of Claudia AV-L-23, from the atlas of the giant asteroid Vesta, was created from images taken as NASA's Dawn mission flew around the object, also known as a protoplanet.
This composite image, which has become a popular poster, shows a global view of Earth at night, compiled from over 400 satellite images
Earth at Night
Saturn's moon Tethys displays its distinctive dark equatorial band here, along with two sizeable impact craters in the west. The larger crater to the north is Odysseus, which has a diameter (450 ki...
