A new video of astronauts attempting to work out what the hell three floating “orbs” are out the window of the Space Shuttle Atlantis has emerged. It was filmed on the Shuttle’s final mission in space. NASA ground control thinks it’s just lens reflections of space junk and it could be right, but the astronauts don’t seem so convinced.

“It’s a structure that’s definitely not rigid. Doesn’t look like anything I’ve ever seen on the outside of the Shuttle, that’s for sure.”

Honestly, it’s hard to tell what the hell they are; just three apparently spherical looking objects floating around the shuttle. You can hear the astronauts try and describe them in the first section of the video, but jump to 4:50 onwards to see the unidentified objects for yourself. One appears to be moving, but the quality of the video is so low it could be a spaceman's empty crisp packet as much as ET coming to check-up on us. It’s probably just space junk. Or is it?
