Back in 2003, NASA sent the Mars Rover to Mars for a mission that was supposed to last for 90 days. Miraculously, the Mars Rover actually continued roaming about and snapping photos for 6 YEARS!
During that time, hundreds of photos were taken. Someone (who has a ton of time on their hands) searched through the photographs and located one that seemed a little strange.
Off in the distance of the photo, what appears to be a UFO hovering above the surface of Mars is caught in the image!
Some people say this is proof of UFO's watching us. Some say it's a spec of dust on the lens. Check out the video below and see what you think!
