Sunspots ebb and flow in a cycle of approximately 11 years. A new prediction suggests that the current Sunspot Cycle 25 could exhibit unusually strong activity, contrary to official forecasts that ...

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 ...

BOULDER — The next sunspot cycle will be 30-50% stronger than the last one and begin as much as a year late, according to a breakthrough forecast using a computer model of solar dynamics developed by ...

NASA scientists are warning that the sun may be "waking up" from a brief period of relative inactivity, contradicting past assumptions about our home star. If true, this could mean that decades of ...

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 ...

With several solar flares and coronal mass ejections soaring out into space, the sun has had an active few months as the current solar cycle gathers momentum. This solar cycle, Solar Cycle 25, is ...

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 ...

PORTLAND, Ore. (KOIN) – A sunspot that’s larger than Earth has the potential to produce solar flares, but a space science expert said this is normal activity for the sun’s current cycle. Active Region ...

Proof that the current sunspot cycle is percolating right along comes with the appearance a large, new sunspot group that's quadrupled in size over the past few days. Active region 2936 is now about ...

The strongest solar flare in half a decade just launched off the sun from the same sunspot group that triggered dazzling auroras last weekend. But don't expect northern lights this time around. When ...

Sunspot Cycle 24, which is just ending, was quite weak as well, but it was also quite short -- just shy of 10 years long - and that's the basis for the new study's bullish prediction that Sunspot ...
