After a calm week, the sun erupted again. A powerful M5.1 solar flare burst from an emerging sunspot region, shaking the ...

The Sun has just unleashed an M5-class solar flare, a powerful burst of radiation that signals a clear uptick in solar activity as the current cycle heads toward its peak. While this event is not the ...

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.

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

What processes are responsible for heating solar flares and what dangers do they pose to Earth? This is what a recent study published in The Astrophysical Journal Letters hopes to address as an ...

OVRO-LWA radio data contrasts a quiet day (Sept. 29, 2025) with the hours after the X1.7-class flare recorded at 2:35 ET on Nov. 9. The type III radio bursts, shown in the radio dynamic spectrum ...

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

The National Solar Observatory on Mt. Haleakala recorded this high-resolution image of a solar flare on the sun. According to the observatory, the image is about four Earth-diameters on each side.

Solar flares can be many times the size of Earth and can damage things like satellites. A new study suggests that eruptions from the sun can be even hotter than researchers thought. Solar flares are ...

Beautiful yet dangerous solar flares that erupt from the sun could be as hot as 180 million degrees Fahrenheit, researchers say. That's more than six times hotter than solar physicists previously ...
