The massive sunspot that sparked an "extreme" geomagnetic storm in May 2024 unleashed hundreds of other dangerous solar ...

In direct contradiction to the official forecast, a team of scientists led by the National Center for Atmospheric Research (NCAR) is predicting that the Sunspot Cycle that started this fall could be ...

The solar cycle continues to ramp up with currently the largest number of sunspots in the last two decades and maybe even longer. NOAA’s Space Weather Prediction Center(SWPC) reports the estimated ...

Federal forecasters are warning of a severe solar storm through Tuesday that potentially threatens satellites, orbital communications and some infrastructure. The warning follows a volley of solar ...

A new 11-year cycle of heightened solar activity, bringing with it increased risks for power grids, critical military, civilian and airline communications, GPS signals and even cell phones and ATM ...

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 ...

One way to track the solar cycle is by counting the number of sunspots, which are dark, cooler patches on the Sun’s surface.

Using modern techniques, researchers have re-examined Johannes Kepler's half-forgotten sunspot drawings and revealed previously hidden information about the solar cycles before the grand solar minimum ...

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 ...

How can 400-year-old sunspot drawings help modern-day scientists with solar cycles? This is what a recent study published in The Astrophysical Journal Letters hopes to address as an international team ...

WASHINGTON - When the sun sneezes it's Earth that gets sick. It's time for the sun to move into a busier period for sunspots, and while forecasters expect a relatively mild outbreak by historical ...
