Sunspot AR3089 erupted with a series of m-class flares that culminated with an M7-class flare on Aug. 26, 2022. NASA's Solar ...

Like the number of sunspots, the occurrence of solar flares follows the approximately 11-year solar cycle. But as the current Solar Cycle 25 approaches its peak, how are the number of solar flares ...

Solar flares heat ions much more strongly than electrons. The finding offers a new explanation for spectral line broadening. Recent work from the Andrews suggests that particles in solar flares can ...

Have you seen the Northern Lights? They're more than just pretty colors; when you see them in Pittsburgh, there's science ...

This is the conclusion of researchers from the University of St Andrews, Scotland, who found that the positively charged ions in solar flares—one of the two key components of solar plasma—can be ...

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.

The Sun emitted two solar flares on April 19, 2022, one moderate peaking at 9:35 p.m. EST and one strong peaking at 11:57 p.m. EST. NASA’s Solar Dynamics Observatory, which watches the Sun constantly, ...

The sun has a bone to pick with Earth — and it’s not done yet. A colossal solar storm just zapped the daylight side of the planet, causing global blackouts and knocking out radio signals across Europe ...
