New seismic imaging shows magma lingering beneath quiet Cascade volcanoes, shaping how scientists monitor and plan for eruptions.

Studies reveal that beneath seemingly tranquil mountains, magma boils in shallow layers, reducing volcanic warning time.

In addition to shaping the interior of rocky planets, molten rock located deep within these planets may also contribute to the creation of a planet’s magnetic fields, which protect the entire planet ...

"A strong magnetic field is very important for life on a planet." ...

Deep beneath the surface of distant exoplanets known as super-Earths, oceans of molten rock may be doing something extraordinary: powering magnetic fields strong enough to shield entire planets from ...

A spot in eastern Africa called the Afar Triangle marks the meeting point of three rift zones—lines where Earth’s crust is being rent apart. Researchers haven’t been sure exactly what drives this ...

Deep beneath your feet, far beyond where any drill can reach, something strange is hiding. Two continent-sized blobs of rock sit just above Earth’s core, hot, dense and stubbornly different from ...

Some 4.6 billion years ago, Earth was nothing like the gentle blue planet we know today. Frequent and violent celestial impacts churned its surface and interior into a seething ocean of magma—an ...

After 24 years diligently studying Earth's magnetic field, a satellite will mostly burn up over the Pacific Ocean on Sunday during a "targeted" re-entry into the atmosphere, in a first for the ...
