Mystery hole spotted at the south pole of Mars

Posted on Monday, 5 June, 2017 | Comment icon 16 comments

What was responsible for creating this hole ? Image Credit: NASA / JPL-Caltech
NASA's Mars Reconnaissance Orbiter has discovered a rather unusual feature on the planet's surface.
Discovered within the 'Swiss cheese terrain' of melting frozen carbon dioxide on the Red Planet's southern polar region, the deep, circular pit, which measures hundreds of meters in diameter, has proven something of a mystery and has left scientists scratching their heads.

The surface of Mars is known to be home to countless holes and openings however most can be easily explained as either meteor impact craters or as features created by volcanic activity.

While deeper than most of the other holes dotted around the region, it is possible to see the bottom of this particular pit thanks to the telltale glint of white where the ice has settled inside it.

So did something fall from above or did the hole open when something gave way underneath ?

The answer remains, for the moment at least, unknown.

Not to worry anyone. I am 100% positive that in the coming years our illustrious and glorious scientists will tell us exactly why there is a hole there. It wont be based on any concrete evidence, or observation not even testable data, they will just imagine why it's there andwe will have our answer. You know like all of science that is currently faith based on extremely circumstantial evidence. Science the modern days faith based religion.

In the past it had extremely active volcanism: witness Olympus Mons

Too "nice" to be an impact crater, not active enough to be volcanic Yep, sinkhole, melting carbon ice etc. OR ET digging for Oreo's....
