Do you know the sunset is blue in Mars?
So, why is the sunset blue?
Mars is known as the red planet, due to its pervasive red dust. But it’s actually that dust that creates the blue sunset.
On Earth, the particles in our atmosphere scatter blue light (that’s why we see the sky as blue). On Mars, though, it’s the opposite. The red dust scatters red light, making the sky a reddish-orange colour. But at sunset, the blue light remains, hence the blue sunset.
