Most of the time, the Earth and Sun’s magnetic fields are misaligned, leaving our planet’s field less open to the aurora-causing effects of the solar wind. However, towards the equinox, the two fields ...

High-speed winds from a spot on the sun’s surface may affect Earth’s magnetic field, pulling the phenomenon further south.

During solar minimum, the sun's magnetic field is close to a dipole, with one north pole and one south pole, similar to Earth's magnetic field. But as we shift toward solar maximum, "the sun's ...

Thus, if we can date the rocks, we can tell north from south in that era. Reversals don’t happen instantly, but over a period of thousands of years as the magnetic field gradually weakens. Though its ...

Aurora chasers are on high alert for possible geomagnetic storm conditions from March 4 to March 5. Northern lights possible ...

Fluid-rock interactions on ancient Mars may have produced abundant magnetic minerals that preserved unusually intense records ...
