What Scientists Found in 1.4 Billion-Year-Old Air Is Reshaping Our Understanding of Early Earth ...

Researchers have made a new discovery that changes our understanding of Earth's early geological history, challenging beliefs about how our continents formed and when plate tectonics began. A study ...

New method reveals chemical signs of early microbial life in ancient Earth rocks, showing photosynthesis evolved much earlier ...

Earth’s earliest crust may have looked a lot more like the continents we know today than scientists once believed. A recent study shakes up old ideas about how Earth's surface evolved, showing that ...

Earth is fortunate in having a magnetic field: it protects the planet and its life from harmful cosmic radiation. Other planets in our solar system—such as Mars—are constantly bombarded by charged ...

Geophysicists have modeled how Earth’s magnetic field could form even when its core was fully liquid. By removing the effects of viscosity in their simulation, they revealed a self-sustaining dynamo ...

About 4.5 billion years ago, the most momentous event in the history of Earth occurred: a huge celestial body called Theia collided with the young Earth. How the collision unfolded and what exactly ...

Continental clues: Modern continental rocks carry chemical signatures from the very start of our planet’s history, challenging current theories about plate tectonics. Researchers have made a new ...
