Scientists have discovered a bullseye crater on Mars and are trying to figure out how it was created:

I love your disclaimer in the thread title. :lol:

offtopic:

It looks to me like a 'splash crater' (nothing to do with water) where material of a different consistency is thrown further out - i.e. there were different layers of sediment.

I've just checked Wikipedia and they don't list it. :confused: I could have sworn this was a proper term. I could be getting mixed up (or talking complete nonsense, for all I know)

Another possibility is that by sheer coincidence, two craters were formed in the exact same spot - one newer and one older.

perhaps two objects, which had been one, broke up on entry, had the same tragectory yet different mass. they would hit the same place relatively simultaneously, but would have two debris rings.

the second ring has scarring outward across it circumference, yet the inner one does not.
 
It looks like a ant lion made it. Ant lions live in sandy soil and bury themselves in a crater. When a ant gets caught int he crater it falls to the bottom where the anti lion under the sand grabs and eats it. The ant disappears below the soil. The ant lion bellows up air from below making the center of the crater look like that. So maybe it was a pocket of some form of gas trapped under the soil from what ever made the crater and it escaped like a bubble pushing up the center.
 
It's a fantastic image. I wonder why we can see impact craters that show direct impact, but we don't see craters caused by meteors skimming the side of a planet. I mean, if luck has an impact with a planet at all, why always full-on, and apparently not 'just on the edge?':confused:;)

Click to expand...

I'm not very smart... but wouldn't gravity stop that?
 
I love the warning for your thread lol. I love this kind of stuff I just wish our space program had the funding it used to.
 
The second one is fake. (I made it.) The first one was provided by NASA. I doubt if it's fake.
