Earth's crust today has a surprisingly similar composition to the planet's first outer shell, or "protocrust," new research ...

Scientists believe a crater found in the Australian outback may be the oldest-known meteor crash site in the world. As AFP ...

Green oceans on early Earth, shaped by iron, pushed microbes to evolve light-absorbing tools that worked in green light.

That led them to consider that these ancient aquatic organisms actually fed on iron to fuel photosynthesis, and they must have, as the oceans didn’t have oxygen eons ago. Does that mean the ocean was ...

One thing geology teaches us about is the existence of another monumental event in the history of Earth, 2.4 billion years ...

Earth is the only known planet which has plate tectonics today. The constant movement of these giant slabs of rock over the ...

New research suggests that Earth's first crust, formed over 4.5 billion years ago, already carried the chemical traits we ...

Microbes - alive and thriving -- have been found sealed within a fracture of 2-billion-year-old rock beneath Earth's surface.

Modern continental rocks carry chemical signatures from the very start of our planet's history, challenging current theories about plate tectonics.

Microbial organisms dominate life on Earth, but tracing their early history and evolution is difficult because they rarely ...

Moon is slowly moving away from Earth at a rate of 3.8 centimetres per year. This gradual drift affects Earth’s rotation and ...
