Watch Colorful Sunsets on Distant Planets in This NASA Simulation

New models from a NASA scientist show what the sun’s setting might look like on Venus, Uranus and Mars

A near-infrared, color image taken by NASA's Cassini spacecraft shows the sun glinting off of north polar seas on Saturn's largest moon, Titan. Similar glints were spotted from Earth in 2000 at Titan's equator but Cassini found no evidence of liquid there.
