The continent-sized blobs are much hotter than the lower mantle, creating a significant temperature gradient in the rocky ...

From galaxies to the Sun, new research explains how turbulent motion can produce large-scale magnetic fields that remain ...

A groundbreaking study,published in Nature Geoscience, has revealed the existence of two massive blobs of superheated rock ...

All celestial bodies—planets, suns, even entire galaxies—produce magnetic fields, affecting such cosmic processes as the ...

Scientists suggest superionic “hot black ice” deep inside Neptune may explain its tilted, offset and chaotic magnetic field, ...

Scientists are mapping the Milky Way galaxy’s invisible magnetic field, revealing how it holds the galaxy together and ...

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

Ancient magnetic fossils reveal that animal navigation using Earth’s magnetic field may have evolved far earlier than ...

Like Earth, Mars once had a strong magnetic field that shielded its thick atmosphere from the solar wind. But now only the magnetic imprint remains. What's long baffled scientists, though, is why this ...

A new model contradicts previous theories that the sun's magnetic field originates deep inside its interior. Deep origin theories could not explain rotation patterns of the sun's gas near its surface ...

Computer simulation of a one-sided magnetic field on early Mars based on data from a study led by the University of Texas Institute for Geophysics. The study could explain the unusual magnetic imprint ...
