Multiple Coronal Mass Ejections are heading toward Earth. Northern lights are possible when the energy strikes our upper ...

Last spring, the strongest geomagnetic storm in two decades slammed Earth, producing light displays across the Northern ...

A strong geomagnetic storm unleashed by multiple magnetic eruptions on the Sun means many Americans in the Lower 48 could be treated to quite a spectacle late Tuesday night and early Wednesday morning ...

The planet's once-strong magnetic field appears to have been limited to its southern hemisphere, the apparent result of a fully liquid inner core that differs from that of Earth ...
