New research challenges the long-held idea of “geomagnetic saturation,” suggesting Earth’s response to powerful solar storms may continue increasing instead of reaching a natural upper limit.

New research led by NASA Goddard found persistent “erroneous measurements” skewing past estimates for how severe geomagnetic storms can get.

A gigantic solar eruption in November 2021 defied expectations. Two spacecraft—Solar Orbiter at 0.85 AU and Wind at 0.98 AU—watched the same coronal mass ejection (CME) as it zoomed through the solar ...

A solar storm is a sudden explosion of particles, energy, magnetic fields and material blasted into the solar system by the sun When directed towards earth they can create a disturbance in our ...

The solar cycle can be irregular, but some patterns might be trackable—enough to provide a heads-up before extreme weather events.

The United States' largest solar radiation storm in more than two decades could create a dazzling northern lights display, and it may be visible in areas that typically don't see such a stunning sight ...
