Magnetic fields that stretch across thousands of light-years should take a very long time to organize. Standard dynamo theory ...

Astronomers have detected ordered magnetic fields in galaxies so young that conventional models struggle to explain how those ...

How fast can a galaxy build ordered magnetic fields spanning thousands of light-years? Existing theories say several billion ...

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 ...

Researchers have identified a potential mechanism that explains how turbulent plasma can produce the vast, ordered magnetic fields observed across the universe Cosmic magnetic fields are everywhere, ...

A team of scientists from the University of Liverpool have found two strange anomalies that have affected the Earth's ...

Scientists discover that the Earth's magnetic poles can take up to 70,000 years to reverse, much longer than previously thought.

More than a decade of satellite monitoring has mapped Earth’s magnetic field as it subtly altered between 2014 and 2025 — and what scientists have learned is remarkable. The South Atlantic Anomaly, a ...

New observations from the National Science Foundation National Radio Astronomy Observatory's (NSF NRAO) Karl G. Jansky Very Large Array (NSF VLA) provide compelling evidence supporting a universal ...

External sources, such as the early solar wind or Earth’s magnetic field, were too weak or faded too early. Internal sources like a magma ocean or mantle-core precession might have helped, but ...

New observations are helping scientists peer beneath the Sun’s surface, revealing where its magnetic activity may truly begin ...
