You could get more opportunities to see supercharged auroras over the next few months, thanks to our very active sun. Solar activity waxes and wanes on an 11-year cycle. The current cycle, known as ...

The sun is on the verge of a significant event: a magnetic field reversal. This phenomenon happens roughly every 11 years and marks an important stage in the solar cycle. The shift in polarity ...

Solar activity is likely to be on the decline all the way to 2030, which will mark the end of Solar Cycle 25.

BOULDER–Challenging conventional wisdom, new research finds that the number of sunspots provides an incomplete measure of changes in the Sun’s impact on Earth over the course of the 11-year solar ...

The unexpected surge of solar activity during the ongoing solar maximum may be tied to a lesser-known, 100-year-long cycle that is just beginning to ramp up again, a new study suggests. If that's true ...

Like the number of sunspots, the occurrence of solar flares follows the approximately 11-year solar cycle. But as the current Solar Cycle 25 approaches its peak, how are the number of solar flares ...

Solar scientists have spotted indications that the next solar cycle is beginning. That is despite the fact that it isn't due for another six years, and the current solar cycle (Cycle 25) is still in ...

Our sun has officially hit its solar maximum, with increased rates of auroras and solar flares expected in the coming months, NASA has announced. The sun goes through 11-year cycles of activity, ...

This split image shows the difference between an active Sun during solar maximum (on the left, captured in April 2014) and a quiet Sun during solar minimum (on the right, captured in December 2019).

Every morning, astronomer Steve Padilla takes a short walk from his home to the base of a tower that soars 150 feet above the ground. Tucked in the San Gabriel Mountains, about an hour’s drive north ...
