Is this a BUILDING on Mars?

Now hobbyists are combing through pictures of the planet taken by robots searching for signs of life - and they think they have found something.

A massive metallic-coloured dome has been spotted overlooking the barren landscape in an official NASA picture which Ufologists say CANNOT be natural.

David Gannet posted his find on Facebook, where it was quickly picked up by the Mars Moon Space Photo Zoom Club, which said it could be "smoking gun" evidence.

Conspiracy website Unsilent Majority said of the image: "It is obvious that the mysterious dome is not like the surrounding terrain and that it really stands out in the image.

"It could be that this structure is a part of an ancient one, built by those who inhabited Mars in the past. Such pieces of evidence should not be ignored."

The discovery of the dome follows the finding of what seemed to be a massive face carved into a pyramid on the Martian landscape.

NASA announced earlier this year that it believed salt water was flowing down through Mars' canyons and craters during summer.

It was a huge breakthrough, because scientists believe water is a vital ingredient for life and so the possibility arose of an alien race.

Now the possibility of humanity's first Martian colony has been raised by the £3.9bn Mars One project, which has selected five Brits for a one-way trip to the planet.

The first trip, planned for 2024, is privately funded and will be filmed for a reality show.
