Love sunsets? Always wondered how the sun looks like from other planets? Now you can know for sure, thanks to a scientist at NASA who can simulate sunsets on other planets. By Amitha Ameen

A planetary scientist from NASA’s Goddard Space Flight Center in Greenbelt, Maryland,
Geronimo Villanueva has come up with a way for us to see the sun from different planets and moons, albeit through simulations.

The Nasa scientist created the sunset simulations while building a compute modelling tool for a future mission to Uranus, the fourth largest planet in the solar system. The simulations were created to help scientists entering Uranus’s atmosphere to be able to “interpret the measurements of light that will reveal its chemical makeup.”

Each planet’s atmosphere influences the colour of its sun and we all know that the sunlight is made up of the colours of the rainbow. Villanueva has created animated sunset simulations for Venus, Mars, Uranus, Earth, and Titan, and for the viewer, it looks like they are looking through a super-wide camera lens at the sky.

“As these worlds rotate away from the light of the Sun, which is what happens during a sunset, photons get scattered in different directions depending on the energy of the photons and the types of molecules in the atmospheres. The result is a lovely palette of colours that would be visible to those standing on these worlds,” said NASA.

While the sunlight in Uranus is a rich royal blue, Mars moves from a brown to a more blueish tone, whereas Venus moves from a yellow to a more brownish tone. These simulations were created to validate the accuracy of the computer modelling tool created by the NASA scientist, and will one day help scientists when they attempt to probe through Uranus’s atmosphere.
