Discovered What Are The Strange Objects Found On Mars And Moon!

Nowadays, big discoveries are often coming from them.
They are as useful as telescopes and let us observe and study our solar system with an amazing grade of precision.
The thing is, we often find something completely new and…unexpected!
For example, take a look at this picture taken on the moon by China’s Yutu-2 mission:
