An asteroid bombardment impacted both the Moon and Earth roughly 800 million years ago, new research suggests. By dating the craters on the Moon, researchers were able to estimate when the Earth ...

Earth and the moon were bombarded by an asteroid shower 800 million years ago larger than the asteroid responsible for the extinction of the dinosaurs, according to a new study. It may have ...

The researchers' idea that Earth once had rings comes from reconstructions of Earth's plate tectonics from the Ordovician period—which ran between 485.4 million years and 443.8 million years ago ...

About 800 million years ago (mya), before the supercontinent Pangea formed, the Earth was more diverse than classical theory suggests. By reconstructing the tree of life from the evolutionary ...

800 million years ago, Earth's oceans saw an increase in nitrogen, ... But eukaryotes kept a “low profile” until about 800 million years ago, says Xiao, who is a co-author on the new study.

Instead, it was the result of a near-impact with a very large asteroid 466 million years ago. The asteroid passed so close to Earth that its gravity caused it to disintegrate, leaving its debris ...

Anyone living on Earth between 720 million and 635 million years ago probably would've needed a jacket. Geologists have long suspected that Earth's temperature dropped dramatically during this ...

The temporary structure likely consisted of debris from a broken-up asteroid. Earth may have sported a Saturn-like ring system 466 million years ago, after it captured and wrecked a passing ...

If you were to look up from Earth some 466 million years ago, you might have seen a gleaming ring stretching across the sky, some scientists say.

This newly discovered event, however, that occurred 800 million years ago involved an asteroid shower with a total mass between 30 to 60 times that of the asteroid that created Chicxulub.

Over the course of Earth's ancient history, our planet has been blitzed with a variety of foreign objects, some of which may have triggered major events shaping this place we now call home.
