An amazing discovery.
Michael Hindes was at his grandparents house in Massachusetts. His grandmother had recently passed and he was looking for photos of her.
That's when he found a series of pictures of the 1986 Space Shuttle Challenger disaster at the bottom of a box.
He posted the images on social media website, Reddit and they went viral.
Hindes was in 4th grade when the disaster shook the world, but his grandfather was a contractor for NASA at the time.
Nearly 28 years after that memorable day, CNN's Don Lemon asked him about this incredible find.
"It's absolutely extraordinary," said Hindes.
Hindes tells us he's reached out to NASA about the photos but hasn't heard back.
