A breakthrough in solar imaging: the new Cona adaptive optics system enables high-resolution observations of the Sun’s corona ...

A team of solar physicists has released a new study shedding light on the fine-scale structure of the sun's surface. Using ...

A year ago this weekend, the sun’s activity created some of the most spectacular auroras on record, with displays visible as far south as Florida. The incredible spectacles last May (and another ...

The recent CME and solar flare events occurred while the Sun was on a general downward trajectory in terms of activity after reaching the peak of Solar Cycle 25 in late 2024. NASA says that during ...

A recent study from the University of Tsukuba and the National Institute of Advanced Industrial Science and Technology in Japan, published in Chaos, examined the sun’s impact on seismic activity. The ...

The sun’s activity is set to remain intense throughout 2025, marking the solar maximum of Solar Cycle 25. This period will see an uptick in solar flares, coronal mass ejections (CMEs), and ...

New images of the sun captured by the Solar Orbiter mission showcase the highest-resolution views of our star’s visible surface ever seen, revealing sunspots and continuously moving charged gas ...

Recent high solar activity has been causing an unexpected headache for satellite operators in the last few years, and it’s only increasing. Solar activity includes phenomena such as sunspots ...

"During solar maximum, the number of sunspots, and therefore, the amount of solar activity, increases,” said Jamie Favors, director of NASA's Space Weather Program. “This increase in activity ...

The sun's magnetic activity—the origin of the solar wind and the resulting bright aurora displays—is calculated daily by counting sunspots on its surface. Sunspots are magnetic disturbances on ...

"We found that the recovery of solar activity after the Maunder minimum ... numbering and listing the sunspots he observed, as well as diagrams that indicated their positions on the sun's disk.
