Taken out of context, you may not have even guessed that this image wasn’t taken on our own planet. This is in fact a Martian sunset, which looks very much like a sunset on Earth—a reminder that other worlds can appear to be strangely familiar. This incredible image was taken by the Mars Rover Spirit, over the rim of Gusev Crater. Apart from taking pretty pictures, the rover was actually deployed to help study the Martian atmosphere, in addition to looking out for ice and dust clouds. The reddish color is due to fine particles suspended in the thin atmosphere, but the photo has a bluish tint due to the dust, which scatters light forward. Also worth noting is that the Sun appears to be smaller compared to what we see on Earth. This is because the Red Planet is farther than we are from the Sun.
