Learn how some of Earth’s magnetic field flips last longer than others, weakening our defenses against cosmic radiation.

A new radio survey reveals that the Milky Way’s magnetic field is intricate, widespread, and deeply connected to how the galaxy is organized.

Probing the depths beneath our feet is a daunting task. Scientists rely on indirect clues to understand the phenomena at work nearly 1,864 miles (3000 km) deep. It is precisely at this ...

Deep beneath the ocean floor, ancient sediments hint that Earth’s magnetic field sometimes changed far more slowly than expected.

Astronomers have discovered powerful magnetic fields steering gas, dust, and star formation in a dramatic galaxy merger.

A research team from the High Magnetic Field Laboratory of the Hefei Institutes of Physical Science of the Chinese Academy of ...

Enceladus’s geysers power vast electromagnetic wave systems that redistribute energy throughout Saturn’s magnetosphere.

“Enceladus, Saturn’s small icy moon, is famous for its water geysers, but its actual impact and interaction with the giant planet has remained partly unknown. This result from Cassini transforms our ...

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

Geologists have mapped a strange magnetic anomaly in Australia – and in a stunning coincidence, it happens to look remarkably like the continent it lurks beneath. The anomaly seems to feature its own ...

Earth’s magnetic field is often described as a steady shield, but the geological record tells a more restless story. Polarity flips, when magnetic north and south swap places, happen several times per ...
