Millions of people around the world will pause on Tuesday, at least for a moment, to mark Earth Day. It's an annual event founded by people who hoped to stir activism to clean up and preserve a planet ...

Scientists say they have found geochemical traces of Earth’s ancient self hidden far below our feet, suggesting that parts of the planet that existed before the Moon-forming collision 4.5 billion ...

Geophysicists from ETH Zurich and SUSTech, China, have demonstrated the dynamo effect of the Earth’s core in a model in which viscosity has no influence, as is the correct physical regime for the ...

New reconstructions of 540 million years of climate history show the planet tumbling between icehouse and hothouse states, revealing how rare and vulnerable our temperate moment is. Some 4 billion ...

Researchers are learning details about asteroid impacts going back to the Earth's early history by using a new method for extracting precise information from tiny "spherules" embedded in layers of ...

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 ...
