Tomkins and his team reconstructed an unusual rise in the number of meteorite impacts known as the Ordovician impact spike, ...

Impact craters found around the Earth that were made around the same time could be linked to debris falling from a ring, a new study suggests. By Becky Ferreira If you were to look up from Earth ...

In a discovery that challenges our understanding of Earth's ancient history, researchers have found evidence suggesting that Earth may have had a ring system that formed around 466 million years ago, ...

Earth may have had a ring made up of a broken asteroid over 400 million years ago, a study finds. The Saturn-like feature could explain a climate shift at the time.

A recent study claims that Earth may have once had a ring. The theory would explain the presence of an odd density of impact craters around the equator dating back to the Ordovician period.

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 ...

A recent study published in the journal Earth and Planetary Science Letters reveals evidence that Earth may have had a ring similar to Saturn’s around 466 million years ago, during the Ordovician ...

The 23-degree tilt of the Earth’s axis would have caused the ring to present its surface to the sun, casting a shadow in the atmosphere and on the ground below and causing global temperatures to ...

The Ordovician Impact Spike was a 40 million year period ... But if they came from closer to Earth — say, from a ring of debris encircling the planet’s midsection — then it would make much ...

Earth may have had a ring made up of a broken asteroid over 400 million years ago, a study finds. The Saturn-like feature could explain a climate shift at the time.

If Earth captured a passing asteroid around 466 million years ago, it could have ripped it to shreds and formed a ring. This debris would then rain down on the planet, focused on the equator, over ...
