solar flares

Four spacecraft and one ground-based observatory recorded the eruption of a powerful X-class solar flare on March 29, making it the best-observed such event in history, NASA officials said.

The sun erupted with a major solar flare on Tuesday (Feb. 25), an X4.9 solar flare that is the biggest sun storms of the year. See how a familiar sunspot triggered the massive solar storm here.

The sun is our nearest star and the source of all our light and heat on Earth but recent reports have highlighted an ongoing steep decline in solar activity.

A massive solar flare erupted from the sun on Tuesday (Jan. 7), rising up from what appears to be one of the largest sunspot groups seen on the star's surface in a decade, NASA officials say.

Colossal spiral-shaped flows of super-hot plasma have been found on the sun, completing a nearly half-century-long quest to confirm their existence, scientists say.

Astronomers have detected exotic antimatter particles flying from the sun during solar flares — a discovery that could help scientists understand this mysterious sibling to matter.

The sun fired off an M1.5-class solar flare on July 3 as an early preview to the Fourth of July fireworks, NASA officials say.
