A minor geomagnetic storm can still produce a memorable sky. For northern-tier states, that matters on nights when the aurora sits just close enough to the horizon to reward careful timing, dark skies ...

Several studies have predicted that not all geomagnetic reversals have been discovered, but it was unknown in which periods they might be hidden. Researchers led by the National Institute of Polar ...

Earth is nearing the peak of its current solar cycle, and scientists have identified a potential health risk that extends far beyond auroras and satellite disruptions. A newly published peer-reviewed ...

Geomagnetic storms, instigated by disturbances in the solar wind and coronal mass ejections, impart significant energy into Earth’s upper atmosphere. This dynamic input alters the thermospheric ...
