Earth’s magnetic field is often described as a steady shield, but the geological record tells a more restless story. Polarity flips, when magnetic north and south swap places, happen several times per ...

Astronomers have discovered powerful magnetic fields steering gas, dust, and star formation in a dramatic galaxy merger.

Invisible forces, capable of shaping entire galaxies and accelerating cosmic winds to dizzying speeds, have just been observed by astronomers in Arp 220. This merging galaxy system is located ...

Earth’s magnetic field is easy to forget. It doesn’t make noise, it doesn’t flash, and it doesn’t ask for attention. Yet it ...

Researchers using NASA’s SOFIA airborne telescope have found that magnetic fields are trapping the material that feeds the supermassive black hole in the galaxy Cygnus A. Collimated jets provide ...

For the first time, scientists have used satellite data to create a 3D map of the sun's interior magnetic field, the ...

Add Yahoo as a preferred source to see more of our stories on Google. Earth's magnetic field is like an invisible shield that protects our planet from solar and cosmic radiation. While it might not be ...

Scientists have found that extreme solar activity drastically compresses the magnetosphere and modifies the composition of ions in near-Earth space. They are now looking to model how these changes ...

Solar magnetic activity plays a pivotal role in driving a myriad of eruptive events in the corona, including flares, filament eruptions and coronal mass ejections. These phenomena arise from the ...

Compass readings that do not show the direction of true north and interference with the operations of satellites are a few of the problems caused by peculiarities of the Earth's magnetic field. The ...

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 ...
