By tracing solar flare gamma rays, scientists gain new insight into particle behavior that shapes space weather forecasts.

A New Mexico State University (NMSU) astronomy Ph.D. student, who was leading a data cataloging project, findings link ...

The massive sunspot that sparked an "extreme" geomagnetic storm in May 2024 unleashed hundreds of other dangerous solar ...

The chromosphere is a dynamic layer of the sun that is home to flares and other types of solar activity. Astronomers make observations of this layer using a specialized filter, tuned to the wavelength ...

It's been a busy year on the sun, as it officially entered the peak of its roughly 11-year cycle of activity, known as solar maximum. In 2024, the sun launched over 50 X-class solar flares — the most ...

The Sun’s most violent flares are turning out to be even more extreme than I, or many solar physicists, had imagined. By ...

Solar physicists say they have found a key source of intense gamma rays unleashed when Earth's nearest star produces its most ...

The sun is not quite done with 2024. Early Sunday (Dec. 29), the sun fired off a class X1.1 solar flare, one of the most powerful types of solar explosions possible, in what may be its last major ...

Researchers have identified a newly recognized type of extremely energetic particles located in the Sun’s upper atmosphere, revealing a phenomenon that had not been detected before. Solar scientists r ...

A new solar storm is approaching. In 2025 there were several, but they did not have serious consequences. Now, the US ...
