Enceladus from Cassini
NASA's Cassini spacecraft spied this tight trio of craters as it approached Saturn's icy moon Enceladus for a close flyby on Oct. 14, 2015. The craters, located at high northern latitudes, are sliced through by thin fractures -- part of a network of similar cracks that wrap around the snow-white moon.

Jupiter’s Moon Io Casts a Shadow as It Transits Jupiter
The conspicuous black spot on Jupiter is Io’s shadow and is about the size of the moon itself (2,262 miles or 3,640 kilometers across). This shadow sails across the face of Jupiter at 38,000 mph (17 kilometers per second). The smallest details visible on Io and Jupiter measure 93 miles (150 kilometers) across, or about the size of Connecticut.

The Source of Dunes in Chasma Boreale, Mars
This false color image shows dunes during the summer, when they were free from the seasonal layer of carbon dioxide ice that covers the region for much of the year. These dunes, which are near the head of the largest trough in the North Polar cap (called Chasma Boreale), were formed by strong winds blowing down the canyon toward its mouth. False colors are used to gain information about sand particle composition.

Lightning over Colima Volcano, Mexico!
Volcanic lightning is generated by static discharge from ash and other particles colliding as they rise and fall in the volcanic cloud.
