The Moon has a million of them, although they're not so eroded for obvious reasons.

At velocity does this happen. There are crater on Earth (2nd photo I posted) and every other planet. Yet I have not seen this anywhere else. Care to explain why?fitzbew88 said:The basic idea is that a high velocity "object" hits the ground. The object's kinetic energy is turned into heat which melts the soil --- the soil (in a temporary liquid state) rebounds vertically --- bouncing back from the impact. If it cools fast enough it leaves a hemispherical formation (an uplift) in the center of the crater.

Yes.

Well, I'd hazard a guess you just haven't bothered to look at the Moon using some decent binoculars.
You should be able to find images of any closely-photographed planet/moon ( which has little atmosphere ) with similar features in craters.
Here's a picture of Mercury showing many craters with central uplifts.

Now, if you don't mind, my dilithium crystals are slightly misaligned and I've got to get back on it. Our Chief Engineer is a real stickler and I don't want to get on his bad side.

I don't see why that's an anomaly. With all the craters on Mars formed over billions of years, you're likely to get one inside the other from time to time.rohnds said:Lets start with this famous one.

Thats a joke to compare the two.Here's a picture of Mercury showing many craters with central uplifts.

I haven't because I don't how this could have happened. You provided an explanation and now I need details such as velocity ranges, soil type and etc to confirm that theory.He also hasn't explained or backed up his conclusions, yet expects us to give details about ours.
You show me a natural formation with perfect right angled edges (90deg) and perfect square. Then I will admit this is a natural formation.donthizz said:what so special about that?
