Image was taken in 2017 by the Mars Reconnaissance Orbiter and shows 328-foot -wide hole in Martian surface.

Scientists believe it may be a 'portal' leading to an underground world of alien life.

The hole also has a circular crater surrounding it, suggesting that it may have been caused by a meteor impact.

This area could soon become a target of future astronauts landing on Mars .
