Coronal Mass Ejection

New research suggests that the unexpected intensity of the ongoing solar maximum may be partly tied to a lesser-known, 100-year solar cycle. If true, solar activity could spike further in the coming decades. But some experts are skeptical.

There's a chance for G4 (severe) geomagnetic storm tonight, NOAA space weather forecaster Shawn Dahl tells CNET.

Colorful northern lights have decorated night skies in unexpected places, and space weather experts say there are more auroras still to come.
