"A strong magnetic field is very important for life on a planet," study lead Miki Nakajima, an associate professor in the ...

Super-Earths are the galaxy’s “middle children.” They are beefier than Earth but smaller than gas giants like Neptune. We ...

Earths, vast underground oceans of molten rock may be quietly doing the work of life’s first line of defense: generating ...

A layer of molten rock deep inside some rocky planets may be doing more than shaping their interiors. New research points to ...

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 ...

Astronomers have spent the past decade cataloguing thousands of planets beyond the solar system, many of them falling into a ...

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 ...

Material from the crater can "tell the story of the late evolution of the lunar magma ocean," scientists say. A giant impact crater on the moon may contain primordial pieces of the lunar mantle and ...

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 ...

A new analysis of data from NASA’s Galileo spacecraft reveals a subsurface “ocean” of magma–either molten or partially molten–beneath the surface of Jupiter’s volcanic moon Io. The finding, from a ...
