For desert ants, Earth’s magnetic field isn’t just a compass: It may also sculpt their brains. Stepping outside their nest for the first time, young ants need to learn how to forage. The ants train ...

This persnickety number determines the strength of magnetic fields. It figures in everything from motors and generators to audio speakers. Oh, and without it we’d live in eternal darkness.

March 2024 may be the best month in the best year to see the Northern Lights, aka aurora borealis. That's because the sun is hyperactive, and the equinox can create holes in Earth's magnetic field.

How the universe got its large magnetic fields has remained one of the stickiest outstanding problems in astrophysics. Now, researchers have proposed a novel solution: a giant "dust battery" operating ...

Such magnetic fields are "comparable to magnetism generated by [the electrical ... of the cosmic web with the James Webb Space Telescope (JWST) could allow them to create more powerful simulations to ...

Primordial magnetic fields, billions of times weaker than a fridge magnet, may have left lasting imprints on the Universe.

Delving into the realm of geomagnetism and volcanology, scientists have unearthed a fascinating link between volcanic ash and ...

Magnetic fields play an important—if sometimes underappreciated—part in planetary systems. Without a strong magnetic field, planets can end up as a barren wasteland like Mars, or they could indirectly ...
