Instead of water, coronal rain is actually streams of charged solar plasma dropping back onto the Sun’s surface.

Sunspot AR3311 have been extremely active since its emergence in NASA Solar Dynamics views. Seven m-class flares can be seen ...

An M3-class solar flare that lasted about 3 hours created a massive coronal mass ejection. The Solar Dynamics Observatory (SDO) and the Solar and Heliospheric Observatory (SOHO) captured the fireworks ...

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 ...

It rains on the sun, and thanks to researchers at the University of Hawaiʻi Institute for Astronomy (IfA), we finally know ...

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

A high-powered solar flare erupted from the sun last week, causing a major radio blackout in Europe and Asia. The eruption happened at 3:25 a.m., meaning that the sun wasn't in the Texas sky at the ...
