The Moon used to be Earth’s best friend, and in this article, we’ll detail the reasons.
Just in case you didn’t know, four and a half billion years ago, Earth’s surface was a complete mess. Before the emergence of life, temperatures were scorching, and the air was definitely not breathable – it was toxic.
The Sun used to bombard our home planet with massively violent outbursts of radiation – flares and coronals mass ejections.
Streams of charged particles called the solar wind used to threaten the Earth’s atmosphere. Long story short, Earth was uninhabitable back then.
The Moon used to shield Earth
SciTechDaily addresses the fact that there was a shield nearby that helped Earth retain its atmosphere and eventually go on to develop life and habitable conditions.
This shield was the Moon, according to a NASA study that’s been published in the journal Science Advances.
“The Moon seems to have presented a substantial protective barrier against the solar wind for the Earth, which was critical to Earth’s ability to maintain its atmosphere during this time,” said Jim Green, NASA’s chief scientist and lead author of the new study.
He continued and said: “We look forward to following up on these findings when NASA sends astronauts to the Moon through the Artemis program, which will return critical samples of the lunar South Pole.”

The Moon could pose some major risks for astronauts
Speaking of the Moon, not too long ago, we addressed another issue. It’s been revealed by the Extreme Tech online publication that a new analysis of the conditions on the moon shows that there are much higher levels of radiation than previously expected.
This can definitely pose problems for astronauts.
