Solar flares heat ions much more strongly than electrons. The finding offers a new explanation for spectral line broadening.

New research shows that solar flares are six times hotter than thought and calls for updated sun models that could improve ...

The findings, recently published in the Astrophysical Journal Letters, indicate that ions within solar flares may reach temperatures more than 6.5 times higher than earlier estimates, according to ...

A high-resolution image of the flare from the Inouye Solar Telescope, taken on August 8, 2024, at 20:12 UT. The image is about 4 Earth-diameters on each side. “This is the first time the Inouye Solar ...

AP photographer Dmitri Lovetsky had been trying to photograph a plane flying across the disk of the sun for several days.

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 ...
