NASA Scientist Simulates Kaleidoscope of Sunsets on Other Worlds

Geronimo Villanueva, a NASA planetary scientist, created these sunset simulations while building a computer modeling tool for a possible future mission to Uranus, an icycold planet in the outer solar system. To check the accuracy of his tool, Villanueva simulated known sky colors of various planets and moons, some of which are shown in this video. The simulations show these worlds turning away from the light of the Sun, which is whats happening when we see a sunset. As these worlds rotate, photons get sc
