NASA's Curiosity Rover keeps on capturing spectacular photographs on Mars before sending them back on Earth. While several weird things have been allegedly seen in the images released so far, the recent one hides the face of an old man, conspiracy theorists claim.

UFO enthusiasts and alien hunters have so far seen everything and anything on Earth, including a UFO landing site, a crab, a spoon and a pyramid. Now a group of conspiracy theorists claim to have identified the face of an old man in one of the recent pictures clicked by NASA's Curiosity Rover, according to Daily Mail.

The conspiracy theorists believe that millions of years ago, the Last Martian King was decapitated when he lost a brutal battle that took place on the surface of Mars. According to a Martian researcher, NASA's curiosity rover may have clicked a picture of a shrine depicting the face of the "significantly powerful" man on the hillside.

According to conspiracy theorist Scott C. Waring of UFO Sightings Daily, the image of the Last Martian King shows an old man with a beard and moustache. In addition, the old man can be seen wearing a crown over his head.

In his blog post, Waring claims that the micro camre aboard NASA's Curiosity Rover was supposed to capture small things around. However, it focused on a distant hill with the carving of the king.

As apparent from the image, the rover discovered this amazing monument by chance. There mere glimpse of the carving indicates how powerful the king could have been on Mars at one point of time.

Waring explains that power is of the individual depicted in the photograph is evident from the size of the carving and the details with which it has been created. However, it is likely that the carving is nothing but a natural rock formation. The American space agency NASA, on the other hand, has not commented on the claims being made by conspiracy theorists.
