"We believe that the mechanism that 'turns on' these gigantic radio emissions is linked to the formation process of galaxy ...

To map the entire cluster for this novel survey, the team spent 224 hours collecting radio images.

A stream of charged particles known as the solar wind flows from the sun toward Earth. Here, it meets Earth's magnetic fields, which shield our planet like a giant umbrella. The Space Umbrella project ...

Primordial magnetic fields, billions of times weaker than a fridge magnet, may have left lasting imprints on the Universe. Researchers ran over 250,000 simulations to show how these fields shaped the ...

Geophysicists have modeled how Earth’s magnetic field could form even when its core was fully liquid. By removing the effects of viscosity in their simulation, they revealed a self-sustaining dynamo ...

A flower-shaped structure only a few micrometers in size made of a nickel-iron alloy can concentrate and locally enhance magnetic fields. The size of the effect can be controlled by varying the ...
