The icy eyes of Mars


One thing all solid bodies in the Solar System share in common is craters. Some worlds, like Mercury or the Moon, are covered in them, having no atmosphere to erode them away. Earth has relatively few; our dynamic atmosphere and water circulation wipes them out after a few millennia. And some icy bodies like Saturn’s moon Enceladus or Jupiter’s Europa only have a few because their surfaces are also constantly changing… on a geologic timescale.

    1. There are 2 explanation for these craters
      1. It can be formed by asteroid impact.
      2.these aren’t craters. They may be formed by lava or any internal heat source of planet which might be existed in distant past. Much like Yellowstone .

  1. Nice pic. Where on the surface of Mars is that located? Statistically I’d expect concentric craters to happen some time, but an adjacent pair is remarkable.

    1. Yeah, they are really remarkable.
      This photo is taken very recently I have searched about its location but I didn’t get enough information.
      This photo is taken by astronomer phil plait may be you can try to get some information about it.
