Ancient crystals reveal that Earth began recycling its crust and forming continents billions of years earlier than scientists once believed.

Researchers say they discovered evidence that early Earth was home to more hydrogen than previously thought, calling into question widely held beliefs about the origins of water and the planet’s ...

Just over 4 billion years ago, magma from Earth’s mantle infiltrated a fracture in the young planet’s primordial crust. Over the following aeons, nearly all of the planet’s early crust ...

A study published in Nature on 2 April reveals that Earth's first crust, formed about 4.5 billion years ago, probably had chemical features remarkably like today's continental crust.

However, the theory has a flaw: Earth's core was completely liquid before Earth's inner core crystallized—around 1 billion years ago.

The study of early Earth microbial life and its associated organic matter provides crucial insights into the origins and evolution of life on our planet. Recent work has illuminated the remarkable ...
