Near Earth's magnetic poles, some of Earth's magnetic field - shown as red in this diagram - loops out into space and connects back to Earth. But some of Earth's polar magnetic field connects directly ...

(Left) 3-D diagram of the magnetic wormhole shows how the magnetic field lines (in red) leaves a magnet on the right pass through the wormhole. (Right) In terms of magnetism the wormhole is ...

The poles of the sun’s magnetic field are fading away. But don’t panic: it’s all part of our host star’s usual 11-year cycle of activity. Over the past couple of years, solar activity—as measured by ...

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 ...

Indian astronomers have investigated an ultraluminous X-ray pulsar in the galaxy NGC 4631, designated X-8. The new study, described in a paper published Feb. 16 on the arXiv preprint server, provides ...
