A big space rock floats in space. Its name is Didymos. It has a tiny moon too! A spacecraft called Hera flew close to it. Hera took a cool photo!

The photo shows a new side. No one saw this side before! Scientists found lines and big rocks on it. A spacecraft hit the tiny moon before. The lines may come from that hit.

Scientists study these space rocks now. They want to keep Earth safe. Hera will take more photos soon. This is a big discovery for us! Space is full of surprises.
