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 are raising alarm bells as Earth’s rotation speeds up unexpectedly, leading to what may soon be the shortest day in recorded history. According to Graham Jones, an astrophysicist at the ...

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 ...

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 ...

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 ...

Scientists have shown that Earth’s basic chemistry solidified within just three million years of the Solar System’s formation. Initially, the planet was barren and inhospitable, missing water and ...

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 ...
