FORMER NASA astronaut and moon walker Dr. Edgar Mitchell - a veteran of the Apollo 14 mission - has stunningly claimed aliens do exist. And he says extra-terrestrials have visited Earth on several occasions - but the alien contact has been repeatedly covered up by governments for six decades. Dr Mitchell, 77, said during a radio interview that sources at the space agency who had had contact with aliens described the beings as 'little people who look strange to us.'

The Stephenville Texas UFO was reportedly seen by dozens of people as the locals claim to have seen a large metal object with bright lights flying low and fast. Some say they saw fighter jets chasing the UFO.
