Mind-blowing Nasa video reveals what sunsets on other planets and moons would look like
NASA has revealed a stunning simulation of what sunsets would look like on different planets and one of Saturn’s moons.
Planetary scientist Geronimo Villanueva from Nasa’s Goddard Space Flight Center is the genius behind the creation.

Nasa wrote in the video description: “Geronimo Villanueva, a NASA planetary scientist, created these sunset simulations while building a computer modeling tool for a possible future mission to Uranus, an icy-cold 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 what’s happening when we see a sunset.
“As these worlds rotate, photons get scattered in different directions depending on the energy of the photons and the types of molecules in the atmospheres.
Three types of sunset on Earth feature in the comparison[/caption]
“The result is a lovely palette of colors that would be visible to those standing on these worlds.”
The Nasa Goddard YouTube account released two videos.
One showing what the sunsets look like if you were looking at the planets and moons while floating in space.
The other shows what it would be like if you stood on the surface.
Earth was given three simulations to show the difference between clear, hazy and overcast sunsets.
The Mars simulation showed how a sunset would change the sky from brown to blue due to how the dust particles scatter on the planet.
TRAPPIST-1e, an Earth size planet outside our Solar System, was also included in the study.
As was Saturn’s largest moon, Titan.
Villaneuva relied on a tool called the Planetary Spectrum Generator for the project.
It can show you evening sky simulations on a variety of planets.
The Sun – all the facts you need to know
What is it, why does it exist, and why is it so ruddy hot all the time?
- The Sun is a huge star that lives at the centre of our solar system
- It’s a nearly perfect sphere of hot plasma, and provides most of the energy for life on Earth
- It measures a staggering 865,000 miles across – making it 109 times bigger than Earth
- But its weight is 330,000 times that of Earth, and accounts for almost all of the mass in the Solar System
- The Sun is mostly made up of hydrogen (73%), helium (25%) and then a number of other elements like oyxgen, carbon and iron
- Its surface temperature is around 5,505C
- Scientists describe the Sun as being “middle-aged”
- The Sun formed 4.6billion years ago, and tt’s been in its current state for around four billion years
- It’s expected that it will remain stable for another five billion years
- It doesn’t have enough mass to explode as a supernova
- Instead, we expect it to turn a hulking red giant
- During this phase, it will be so big that it will engulf Mercury, Venus and Earth
- Eventually it will turn into an incredibly hot white dwarf, and will stay that way for trillions of years
