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 ...

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 ...

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 ...

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 ...

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 ...

"Their magnetic fields—which arise from minuscule details of the planet's makeup—can tell us a lot about their formation and evolution, and the evolution of our universe." The team will incorporate ...

Twenty bonnethead sharks were given an unusual test at a Florida State University laboratory in 2021: could they tell where ...

More often than not, anything “quantum” makes you think of stuff on the tiniest of scales. But in reality, quantum phenomena ...

Pigeons can sense Earth’s magnetic field by detecting tiny electric currents in their inner ears, a team of researchers suggests. Such an inner compass could help to explain how certain animals can ...

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 ...
