A vast, volatile blemish has opened on the face of the Sun, and it is already rewriting the current solar cycle’s record book. The decade’s largest sunspot, a complex tangle of magnetism more than ten ...

North Central and Northwestern states have the best chance of viewing. The peak of the current solar cycle is ongoing, bringing spectacular views of the northern lights to several U.S. states. A ...

The Sun has just unleashed an M5-class solar flare, a powerful burst of radiation that signals a clear uptick in solar activity as the current cycle heads toward its peak. While this event is not the ...

Activity on the sun is not constant; it varies along a cycle of about 11 years. The peak of this solar cycle — called solar maximum — is when sunspots, solar flares and coronal mass ejections (CMEs) ...

With the Sun still in an active phase there could be more spectacular Northern light displays in the year ahead.

People in the U.S. were treated to stunning auroras last week when a powerful geomagnetic storm pushed the celestial displays as far south as Florida and Mexico. The spectacle was particularly ...

Scientists charged with predicting the sun's activity for the next 11-year solar cycle say that it's likely to be weak, much like the current one. The current solar cycle, Cycle 24, is declining and ...

A year ago this weekend, the sun’s activity created some of the most spectacular auroras on record, with displays visible as far south as Florida. The incredible spectacles last May (and another ...

Forbes contributors publish independent expert analyses and insights. An award-winning reporter writing about stargazing and the night sky. A forecast for potentially “severe” Northern Lights ...

People in the U.S. were treated to stunning auroras last week when a powerful geomagnetic storm pushed the celestial displays as far south as Florida and Mexico. The spectacle was particularly ...

Solar cycles, characterized by fluctuating sunspot activity, occur approximately every 11 years, although their duration varies between 8 and 14 years. The study of solar cycles dates back to the ...
