‘UFOs’ spotted in the U.S. - PHOTOS

A strange circle of lights lit up the sky above Houston last Monday, leading many residents to believe they had been visited by extra-terrestrials.People quickly took to Twitter to post pictures of the spectacle, while others attempted to debunk the claims.

Houston is 666 miles from Roswell (spooky, right?) so maybe the aliens were looking for their friends who conspiracy theorists believe crash-landed there in 1947.

Vice president for Astronomy at the Houston Museum of Natural Science Dr. Carolyn Sumners urged people to remain sceptical.

She told KPRC: ‘I think the trick in UFO’s is figuring out what else they could be.

‘It’s easy to say that could be the aliens.’
