Astronomers are getting a better look at Neptune's moon, Triton, than ever before. They've created a color global map of the moon using historic footage from NASA's Voyager 2 spacecraft, which first gave scientists a glimpse of the moon in 1989.
When Voyager 2 first imaged Triton, most of the northern hemisphere was in darkness. Because of the speed of Voyager's visit and the slow rotation of Triton, only one hemisphere was seen clearly at a close distance. The rest of the surface was either in darkness or seen as blurry markings.
