Scientists and Astronomers have accounted for some dark caverns reportedly seen on the Mars’s terrain. These dark images of the so-called caverns give a first impression of some trick done through Photoshop software but NASA’s Mars Reconnaissance orbiter imagery confirmed that these dark images are definitely of some strange cavern entrances.

Look carefully at the picture, the dark spot in the middle confirms to be a hole in amidst of lava. Scientists and researchers confirmed that it cannot be an impact crater as it does not have a heaved rim called the “Ejecta”. It is surely a deep hole / cavern as light from the sun never seems to return from it. This kind of phenomenon is only seen when there is a deep cave type opening on the surface of a planet. The scientists assume it to be some deep, dark chamber with collapsed or caved-in roof. They also opine that it may be having sharp vertically rising walls.

They are fascinated by this imagery for sure.
