Researchers have recreated the tumultuous beginnings of Earth, simulating what the planet was like just after its formation 4 ...

Earth formed about 4.6 billion years ago, during the geological eon known as the Hadean. The name "Hadean" comes from the ...

Researchers used zircons and AI to reconstruct Earth's ancient crust, revealing possible tectonic processes from the planet's ...

The Hadean and Eoarchean epochs were the real hell on Earth. For millions of years, our planet was heavily bombarded by ... as a result of large collisions as late as about 4 billion years ago.

But the whole planet probably transitioned to the plate tectonic system later, between 3.2 billion and 2.7 billion years ago. There's far more evidence of rocks getting recycled and pushed around ...

And about 2.4 billion years ago, it’s thought that the total amount of landmass on Earth would have been about two-thirds of what we see today, with the emergence of new land happening rapidly.

UCLA geochemists have found evidence that life likely existed on Earth at least 4.1 billion years ago — 300 million years earlier than previous research suggested. The discovery indicates that life ...

While scientists know that our planet first formed about 4.5 billion years ago, the oldest evidence of life are fossil traces of 3.8 billion-year-old microbes called Archaea, Colin Barras writes ...

The map locates the Nuvvuagittuq Greenstone Belt in Canada, home to some of the oldest rocks on Earth. Earth formed about 4.5 billion years ago from a collapsing cloud of dust and gas, soon after ...

And that data at least opens the possibility that life was present at least 4.1 billion years ago. That would be incredible, considering that the planet itself is only a little over 4.5 billion ...

Since the dawn of the planet, the Earth had been a giant ball of water surrounded by an atmosphere rich in methane.That was up until 2.4 billion years ago, when the first landmass abruptly rose ...
