Stunning photos from the Apollo 11 mission are still coming out almost 50 years after a person first walked on the moon.

Michael Collins, who was the Command Module pilot during the historic flight, shared what he says is a previously unreleased photo of the three astronauts in the crew.

"The crew. Found this at the bottom of a box. Don’t think it was ever used by @NASA. #TBT @TheRealBuzz," Collins tweeted Thursday with the "Throwback Thursday" hashtag.

The photo shows Collins standing against a moon replica. Astronauts Buzz Aldrin and Neil Armstrong are photographed on the other side of the moon, with Armstrong's hand on Aldrin's shoulder.
