Solar wind speeds remain elevated as an incoming coronal mass ejection approaches Earth, with forecasts indicating increased ...

The sun is not only our closest stellar neighbor, it's also the star we understand the most. As we've observed it over the ...

Three strong Class M flares were recorded on the Sun. This was reported on December 29 on the website of the Laboratory of ...

While the Sun’s solar flares strongly correlate with sunspots, observations of more than 14,000 other stars show this is not generally the case.

An international team of researchers tracked the active solar region using the Solar Orbiter spacecraft, a joint NASA and ...

On November 1, 2025, sunspot activity on the Sun has increased as new regions rotate into view, according to EarthSky. Currently, only one numbered sunspot region, AR4267, is visible on the ...

A G2 storm, rated “moderate” on the five‑tier NOAA scale, can induce voltage irregu­larities in power systems and affect high ...

Particles within solar flares may reach temperatures more than six times higher than scientists previously believed—offering an explanation to a long-standing astrophysical puzzle about the Sun. This ...

A massive sunspot, over 10 times the size of Earth, has appeared on the sun. It is likely to produce multiple solar flares over the coming weeks, which could lead to bright auroras, the famous ...

Scientists have captured an exceptionally rare, high-resolution view of an active region that produced two powerful X-class solar flares—an achievement rarely possible from Earth. Using the GREGOR ...

With the Sun still in an active phase there could be more spectacular Northern light displays in the year ahead.

Solar activity, manifested primarily through sunspots, solar flares and coronal mass ejections, has long influenced both the near-space environment and terrestrial systems. Over millennia, variations ...
