On Mars, found a huge hole of unknown origin


On Mars, scientists found another puzzle: A huge sinkhole with a diameter of several hundred meters. Surprising right, a substantially cylindrical shape of this formation.

The pictures were taken apparatus Mars Reconnaissance Orbiter, now in its eleventh year of orbiting the red planet. Scientists have put forward several hypotheses about the origin of the failure, none of which fully does provide answers to all questions.


For the failure of the crater shape too correct, next to no specific soil changes. Karst holes also excluded: in the permafrost soil is not sags.


Ufologists, of course, involve the artificial origin of the strange pit. At the moment, NASA plans to consider the possibility of a special truth to this region.
