The aurorae, that we see here on Earth, are a quite extraordinary sight to look at, but, just like Earth, it turns out that Mars also has aurorae observable to the naked eye — with one quite astonishing difference. NASA, ESA,and many other scientists united together to figure out, first, if Mars had observable aurorae, and, second, just what those might look like. To reply their questions, they constructed a model to see if they could reproduce an aurora. Using a planetary simulator set to mimic Martian situations, scientists did generate another-worldly aurorae. But there was one disclosure:
That brilliant blue-purple shadow of light isn’t just an effect of laboratory surroundings, it’s also what you would see if you were blessed enough to be standing on the surface of Mars’ South Pole in the right situations. But although blue is the most common color you’d be likely to see, the green and red aurorae of our planet show up too, with clues of both of those colors (which you can see a bit of in the lower right curve of the simulation) on the borders of the Martain aurorae.
