A persistent "gravity hole" beneath Antarctica gives scientists a window into Earth's deep interior, showing how processes far below reshape the planet's gravity field over millions of years.

Our planet plunged into one of the most dramatic climate states in its long history, approximately 720–635 million years ago.

When we look at the solid ground beneath our feet, it's easy to assume Earth has always been this way. But our planet tells a story so extraordinary, so ...

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 ...

Venus is often called Earth’s twin, but the two planets evolved into dramatically different worlds. Scientists believe the explanation may lie in the planet’s geology and the absence of key geographic ...

Deep within Earth’s mantle lie two enormous regions, often referred to as "islands," which are the size of continents.

Sophisticated analysis of tiny bubbles of ancient gas trapped in volcanic rocks, combined with new geophysical modeling, has cast new light on long-held assumptions about the deep Earth. An ...

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 ...
