Nasa's Curiosity rover spots rock 'circle' on Mars

A mysterious circular rock formation on the surface of Mars has been captured by one of NASA's Orbiters. The formation was photographed by the Curiosity Rover this week and has excited alien hunters who invited speculation over how it came to be online. They suggested that the rocks were'arranged', laid out by another form of life, or that it was part of a larger, buried structure which has never before been seen. NASA's Curiosity Rover has captured a mysterious circular formation on rocks on the surface of Mars Alien hunters were excited by the images (above, after color enhancement) and suggested that the rocks had been'arranged' or could even be evidence of a larger, buried structure'Whatever we're seeing here, it's in a perfect circle and it's much different from the craters that we normally see on Mars and the moon and throughout the other planets in the solar system. This almost looks like these rocks were arranged in this circular formation.
