WASHINGTON D.C. (CNN) – Jaw-dropping images from NASA.

It’s raining plasma on the sun’s surface.

NASA explains a solar flare can cause material to cascade down in big loops – called coronal rain.

That “rain” is made of plasma — a gas in which positively and negatively charged particles have separated.

They form a super-hot mix that rapidly cools as it falls.

The bright pixels in this video aren’t caused by the solar flare.

They occur when high-energy particles bombard the camera on iris — a NASA satellite used to observe the sun.

Interesting to note – the sun’s corona, or outer atmosphere, is much hotter than the sun’s surface.

And scientists don’t know why.
