This event happened 800 million years ago and was as catastrophic as it was fundamental in Earth's climate changes.
800 million years ago, a giant asteroid near Jupiter disintegrated, bombarding the Earth, the Moon and Mars for more than a century. This disaster sheds light on the enigma of ancient lunar craters and its potential link with the "Earth Snowball" and the great evolutions of life.
Researchers at the Southwest Research Institute have linked, in a study published in July 2026 in The Planetary Science Journal, a vast bombardment of the internal solar system to the explosion of a single rocky body 800 million years ago. Traces of such old impacts quickly disappear on our planet, gnawed by erosion and tectonics, when the Moon preserves them almost intact. The rain of asteroids born from this fragmentation would have affected t…
