We assume the light from the sun and the camera are right above the whole. If the light is at an opposite angle as the camera, the whole could be shallow and the same effect would occur.

I’m sure the Mars Global Surveyor took pictures of this area of Mars. It would be interresting to see what they look like.

I don’t know. It looks like a black spot on the picture! It seems that it’s too perfectly round. Just a glitch with the camera?

Worth examining in depth. The South Pole-Aitken Basin on the Moon has an apparant impact crater 12 km deep - more than seven times as deep as the Grand Canyon - and 300 km wide. It's by far the deepest impact crater in the solar system.

This may have been the pivot point for a massive boom-arm used by ancient space-farers to fling carbonaceous chondrites mined from Earth's surface to the vicinity of what is now called the asteroid belt.

All connected guys ~ caves with skylights, pivot points, mining residue, except that all this stuff is 3 billion years old and the detailed remains have withered away into space dust.

It could be more like a shell. :p

Suspicious ...looks more like a touch up job to blot out something the public is not supposed to see. Look along the left edge of the enhanced ... OTH a solidified then indented pool of oil would allow for the same effect of light absorption, wouldn’t it?

Well it does remind me of some of the pics from Titan of lakes of hydrocarbons...but who knows.

The entire planet is hollow. This is just a hole in it.


I thought it was filled with delicious caramel.

When you click on the link, what do you suppose are the bubble-looking thingies next to hole in #A?

Obviously progressives who redeployed to WA, OR & CA.

I would say that a very energetic asteroid made that hole.

Interesting, but I would need to see several more images of the exact same area, taken at different Sun angles.

Physically, these are crater chains in the images provided, and it does not make since how the larger craters would not punch a deeper hole into the surface than the little ones.

At the moment, I will label this as: Interesting, but most likely, only an angle of illumination phenomenon.

Note the pocket of black at the 11 Clock position. This might have some characteristic’s of a liquid filled crater. Anybody have a picture of a water filled crater on earth taken from a satellite? I bet the liquid looks dark.

Look at “D”. That is not a crater, it’s a high prominence with Sun high from two o’clock a shadow to the four o’clock.
