In a remote desert, scientists have discovered one of Earth’s oldest asteroid impacts. It dates to well over a billion years ago, to a time when our planet was inhabited solely by single-celled life.

Seismic imaging has exposed two massive zones hidden deep in Earth’s mantle. These giant blobs, known as large low-velocity provinces, or LLVPs, stretch beneath Africa and the Pacific. They are so ...

Some 2.3 billion years ago, the Earth would have been unrecognizable to us. At that time, ancient microorganisms were the dominant life form; there were no animals, no plant life, and certainly no ...

A study led by researchers from the University of Sydney and the University of Adelaide has revealed how the breakup of an ...

The comet could be older than our solar system. The comet is also distinct because nickel vapor was detected in the gas ...

Sea levels rose and fell many times during the ice age, showing ice sheets were larger and more active much earlier than once believed.

What can fossil records teach scientists about ancient ecosystems and marine environments? This is what a recent study published in the Proceedings of the National Academy of Sciences hopes to address ...

Quasi-moons are not real moons and don't actually orbit the Earth, although they sometimes appear to do so for short periods of time, Phil Nicholson, professor of astronomy at Cornell University, told ...

New research from Japan's iron-rich hot springs shows how early microbes may have harnessed iron and oxygen during the Great Oxygenation Event. Some 2.3 billion years ago, the Earth would have been ...
