Tiny bits of Earth’s atmosphere have been drifting to the moon for billions of years, guided by Earth’s magnetic field.

Scientists announced Monday that Earth is rotating slightly faster than normal, resulting in what is expected to become the second-shortest day ever recorded since precise atomic timekeeping began.

The Mid-Atlantic Ridge in Iceland. This area is the boundary between the North American and Eurasian tectonic plates, which move apart ~ 2.5 cm/year. Subduction and the formation of continents, a ...

For over half a billion years, Earth’s magnetic field has risen and fallen in sync with oxygen levels in the atmosphere, and scientists are finally uncovering why. A NASA-led study reveals a striking ...

Scientists at Yale and in Singapore have devised what may be the ultimate acid test — a comprehensive model for estimating the origins of Earth’s habitability, based in part on ocean acidity. The new ...

COLLEGE PARK, Md. — A University of Maryland-led team of scientists has discovered that diamonds can be natural time capsules, preserving information about the cycling of sulfur between Earth’s crust, ...

Scientists say Earth’s magnetic field may have funneled atmospheric particles to the moon for billions of years. Lunar soil could preserve a record of Earth’s past while providing resources for future ...
