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

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

Add Yahoo as a preferred source to see more of our stories on Google. Deep layers of molten rock inside some super-earths could generate powerful magnetic fields—potentially stronger than Earth’s—and ...

Researchers studying a distant spiral galaxy have found that large-scale, ordered magnetic fields existed far earlier in cosmic history than standard theories predicted, forcing a fresh look at how ...

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, ...

It's well established that the universe is expanding, but there's serious disagreement among scientists over how fast it's happening. Two of our best ways of measuring the cosmic expansion rate, the ...

Forbes contributors publish independent expert analyses and insights. An award-winning reporter writing about stargazing and the night sky. Using 11 years of magnetic field measurements from the ...

Magnetic fields play an important—if sometimes underappreciated—part in planetary systems. Without a strong magnetic field, planets can end up as a barren wasteland like Mars, or they could indirectly ...

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 ...
