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.

These images help to unravel the magnetic mechanisms driving the sun's behavior and shaping the space environment throughout the solar system.

When last year's solar superstorm Gannon slammed into Earth, it not only painted the sky with beautiful auroras, but also shrunk one of the planet's protective layers to just one-fifth its usual size.
