What are magnets? How does a magnet work? Fundamentally, magnets can be explained through quantum mechanics. This video will ...

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 ...

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 ...

At the right point of the orbit and stellar cycle, the star’s chromosphere brightens.

Astronomers have made a series of landmark observations of one of the universe's most violent events. Using the U.S. National Science Foundation Very Large Array (NSF VLA) radio telescope, which is ...

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 ...
