A new NASA study suggests that solar activity will remain high or rise further in the coming decades, contradicting previous assumptions that the sun was quieting down — and scientists "don't ...

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 ...

In a surprising turn of events, the Sun is entering a phase of heightened activity years ahead of schedule, defying official predictions and leaving scientists scrambling to understand what’s behind ...

The sun is powered by the nuclear fusion of hydrogen to helium, deep within its core. Above the sun's surface, however, a different force dominates: electromagnetism. This force is responsible for ...

The first rumblings of the sun's next 11-year solar cycle have been detected in sound waves inside our home star—even though it is only halfway through its current one. This existing cycle is now at ...

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 ...

The present sunspot cycle began in 2019, and experts initially forecast a mild peak in 2025. But solar maximum arrived ...

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 ...

An X7.1 (R3) solar flare erupted from Region 3842 this evening - as seen in this animation (courtesy of jhelioviewer). This was the second strongest flare of Solar ...

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 ...

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 ...

A new, rapidly growing sunspot is slowly rotating towards Earth, and it could become a hotspot for solar activity in the coming days. On Friday, solar astronomy website Spaceweather.com reported that ...
