Nasa scientists are baffled as to what - or maybe even who? - created this unusual hole on the surface of Mars.

The hole was discovered by chance on images of the dusty slopes of the Red Planet's Pavonis Mons volcano.

It appears to be an opening to an underground cavern, partly illuminated to the right of the opening.
