All celestial bodies—planets, suns, even entire galaxies—produce magnetic fields, affecting such cosmic processes as the ...

The sun’s surface is a brilliant display of sunspots and flares driven by the solar magnetic field, which is internally generated through a process called dynamo action. Astrophysicists have assumed ...

Stephen has degrees in science (Physics major) and arts (English Literature and the History and Philosophy of Science), as well as a Graduate Diploma in Science Communication. Stephen has degrees in ...

Earth’s magnetic field nearly collapsed long ago. What saved it explains why life survived and why the planet remains ...

However, our understanding of planetary magnetic fields is limited to the eight planets in our solar system, as we haven't yet accrued much data on the magnetic fields of exoplanets. That could be ...

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 ...

Our Sun is far from a smooth, white ball in the sky. Twisting and looping magnetic field lines rise from its surface like hair, causing dark, transient patches on the surface called sunspots wherever ...

Surprise findings suggest sunspots and solar flares could be generated by a magnetic field within the Sun's outermost layers. If confirmed, the findings could help scientists better predict space ...
