Around a star that is still forming, astronomers have observed a magnetic field coiling around a powerful stream of gas. This ...

"Clearly the sun is not a good standard star for the discussion of stellar activity," Böhm-Vitense wrote. But she wondered if ...

Like Earth, Mars once had a strong magnetic field that shielded its thick atmosphere from the solar wind. But now only the magnetic imprint remains. What's long baffled scientists, though, is why this ...

Image of the Sun taken from the Solar Dynamics Observatory satellite, showing the quiet corona and magnetic structures like coronal loops, which trace the intricate patterns of magnetic field lines ...

What can an exoplanet’s magnetic field teach astronomers about an exoplanet’s atmosphere? This is what a recent study published in Nature Astronomy hopes to address as an international team of ...

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 ...

A new study suggests Ganymede—our neighborhood's biggest moon—still has a hot, churning core cranking out its unique magnetic field. Reading time 3 minutes Jupiter, the biggest planet in our solar ...

Bonnethead sharks have shown remarkable skills in using Earth's magnetic field for navigation. In controlled laboratory ...

First ever supercomputer simulations of Mars with a fully molten core could explain the Red Planet's unusual magnetic field. Billions of years ago, Mars had an active magnetic field. Mysteriously, its ...

Computer simulation of a one-sided magnetic field on early Mars based on data from a study led by the University of Texas Institute for Geophysics. The study could explain the unusual magnetic imprint ...
