Earth's magnetic field

The South Atlantic Anomaly makes a section of the southern aurora weaker and likely dimmer.

On Nov. 3, a solar storm caused a temporary crack in Earth's magnetic field. The resulting hole enabled energetic particles to penetrate deep into the planet's atmosphere and set off extremely rare pink auroras.

It's all thanks to a cliff by a river in Japan.

Strandings of healthy gray whales increase with the prevalence of solar storms.

The Earth's magnetic field might be influencing the brain.

The magnetic field is likely to recover without major disruption, new research finds.

Whales, dolphins and porpoises end up stranded on beaches and no one knows why.

Strange stripelike features in Earth's magnetic field are caused by the planet's spin, and not by the constant bombardment of solar particles as previously thought, scientists say.
