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.

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 ...

Earth's inner core may be layered like an onion, with silicon and carbon creating distinct zones that explain seismic wave ...

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 ...

The Earth's spin isn't as consistent as it may seem. In fact, it naturally drifts and wobbles on its axis over time, and that's generally chalked up to the way mass is distributed and redistributed ...

Using observational and model-based data spanning the entire 20th century, scientists have for the first time have identified three broadly-categorized processes responsible for Earth's spin axis ...

Occasionally, planet Earth will grab the headlines: Underwater volcanic eruptions send ash into the air, or earthquakes generate massive waves that send people running for safety as the rest of us ...

Earth's surface environment hosts large reservoirs of hydrogen (H, mainly in the form of water, H 2 O), nitrogen (in atmospheric N 2) and carbon (mainly in carbonate rocks). H, N and C are sometimes ...

As cities spread across the landscape, they consume and pollute, pushing Earth Systems toward destabilization and the overshoot of planetary boundaries. (Courtesy of NASA). Editor's note: This story ...
