NASA Simulations Show What Sunsets Would Look Like on Other Worlds

Planetary scientist Geronimo Villanueva, from NASA's Goddard Space Flight Center in Greenbelt, has created simulations of how sunsets might look on Venus, Mars, Uranus, the Saturn moon Titan, and Trappist-1e.

On Venus, for example, a bright yellow fades down into orange, brown, and then black as the Sun disappears. Since the planet rotates on its axis so slowly, you'd need to wait around 116 times as long as you would on Earth, which is a little more than half of a Venusian year, Science Alert reports.

These simulations aren't just fun to watch. They have a serious scientific point to them, too - preparations ahead of a potential probe mission to Uranus. There's still a lot we don't know about the gas planet, and any readings of its atmosphere would need to interpret the levels of light reaching the spacecraft's sensors.
