Jupiter’s moon, Callisto.

is no one going to explain what all the lights are

they’re impact craters! callisto is one of the most heavily cratered object in the solar system, and as far as my very basic research has just gone, the light parts are essentially iced over impact craters

so, essentially, we’re looking at something with a very frosty/icy surface. they’re bright because they reflect the sun!

it’s really annoying when people pretend Mars is a valid option for colonization  as some safety net for fucking up Earth “once earth’s resources become depleted”… Like how badly could we possibly fuck up to where Mars (the giant desert planet with no air) becomes a preferred option.. just Recycle
