The Sun

Aurora alert! The colossal solar storm could impact and trigger impressive northern lights.

NASA's Parker Solar Probe captured solar material looping back to the sun, revealing how it recycles magnetic energy and shapes future solar storms.

Scientists have created the first detailed maps of the sun's atmospheric boundary, where solar material breaks free and streams into space.

The powerful X1.1 solar flare from sunspot region 4298 sparked strong radio blackouts on the sunlit portion of Earth at the time of eruption.

What can today's scientists learn about astronomical phenomena from ancient texts?

Levels of potentially dangerous cosmic radiation in Earth's atmosphere rose to a two-decade high in November after a rare solar super-flare pummeled the planet with high-speed particles from the sun.

We don't often get a good look at X-class solar flares from ground-based observatories.

This year marks 30 years of SOHO observing our sun, an extraordinary milestone for a mission originally expected to last only about three years.

A powerful X1.9 solar flare from new sunspot AR4299 triggered strong radio blackouts, as giant sunspot AR4294 rotates into view with more activity likely.
