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

Magnetic fields that stretch across thousands of light-years should take a very long time to organize. Standard dynamo theory puts that timeline at roughly 5 to 10 billion years in galaxies. Yet ...

Scientists tracing small molecular clouds located near the Milky Way disc have “seen” the skeleton of the magnetic field surrounding them for the first time to better understand its ...

Tiny highly uniform magnetic fields are known to pervade the universe, influencing various cosmological processes. To date, however, the physical mechanisms underpinning the generation of these fields ...

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 ...

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 ...

Physicists weren’t sure why Moon rocks brought back during the Apollo missions are more strongly magnetized than models predict ...
