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

Earth’s magnetic field works a bit like a dynamo. It is generated by the movement of molten iron and nickel in the outer core ...

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

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

Magnetic signatures hidden inside rocks tell us a lot about Earth's magnetic field and the way continents and tectonic plates have shifted across millennia – but for some periods, the geological ...

All celestial bodies—planets, suns, even entire galaxies—produce magnetic fields, affecting such cosmic processes as the solar wind, high-energy particle transport, and galaxy formation. Small-scale ...

The magnetic north pole has been wandering through the Arctic for decades, but lately, its changing path has grabbed the ...

For years, scientists noticed that magnetic fields could improve steel, but no one knew exactly why. New simulations reveal that magnetism changes how iron atoms behave, making it harder for carbon ...

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

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

With an advanced technology known as angle-resolved photoemission spectroscopy (ARPES), scientists are able to map out a material's electron energy-momentum relationship, which encodes the material's ...
