Deep inside Earth, two massive hot rock structures have been quietly shaping the planet’s magnetic field for millions of years. Using ancient magnetic records and advanced simulations, scientists ...

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 ...

Who knew that magnetic fields could be so useful? Astronomers are able to use magnetic fields to map our environment within the Milky Way using a technique called Faraday rotation. It works like this.

Learn why the Sun’s magnetic field is just as important as Earth’s and its impact on our planet. The Sun’s magnetic field impacts the movement of plasma on the sun’s surface, but it does not actually ...

Astronomers at the Center for Astrophysics | Harvard & Smithsonian (CfA) have unveiled a first-of-its-kind map that could help answer decades-old questions about the origins of stars and the ...

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 ...

This activity is part of the Science Friday Sun Camp collection! The Sun generates an incredible amount of energy, energy that you can see and feel as light and heat. Other forms of energy from the ...

A controversial technique has produced detailed maps of the magnetic fields in colossal galaxy clusters. If confirmed, the approach could be used to reveal where cosmic magnetic fields come from. By ...
