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 ...

Earlier this week, the number of visible sunspots on our home star fell to zero for the first time in 1,335 days. This ...

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 ...

The Sun experienced its first spotless days in four years, from February 22-24, 2026, indicating a shift towards a calmer ...

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 ...

Like you and I the sun has cycles. None of us escapes the day-night rhythm of sleep and wakefulness. The most visible of the sun's rhythms is the 11 year solar cycle also called the sunspot cycle.

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 ...
