We take as a given that GPS is ubiquitous and available, but that’s a suspect assumption. The U.S.-based Global Positioning System as well as other embodiments of Global Navigation Satellite Systems ...

How fast can a galaxy build ordered magnetic fields spanning thousands of light-years? Existing theories say several billion years, but observations of galaxies in our universe imply shorter ...

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 ...

The Danish physicist Hans Christian Oersted was discussing in the year 1820 about the possibility of electricity and magnetism being associated to one another, and in the process presenting it finally ...

High magnetic fields are a vital tool in many areas of science and technology that impact our everyday lives, from medical diagnostics through magnetic resonance imaging (MRI) to drug discovery ...

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, ...

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