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

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

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 new study suggests molten rock layers within massive exoplanets create powerful magnetic fields that can protect potential ...

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

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 ...

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

A rocky exoplanet outside the Earth's solar system may have an atmosphere, according to new evidence gathered by NASA researchers. The exoplanet, known as super-Earth TOI-561b, was discovered in 2020, ...

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 ...

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 ...

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 ...
