Look closely at these shadows on the Moon's surface: they might mean there are mysterious deep holes on the Moon, the holes that have never seen light at all, and could even reveal secrets about our solar system's history.

The European Space Agency took about 32,000 pictures of the Moon's North Pole from every possible angle, and there are mysterious areas of constant shadow there.

It means that there are some extremely deep holes on the Moon we had never known about before.

An official press release by the ESA says there might be lunar water in the form of ice stored deep inside the Moon.

What's more, the dark deep holes could hold answers to the history of our solar system.

It comes just a day after NASA released about 10,000 stunning snapshots of the Moon from the Apollo mission.

A week ago, the Moon also gave stargazers the reasons to gasp in amazement: the supermoon and combined eclipse at the end of September caused a social media storm.
