Rain on the Sun

This video was forwarded to me by a friend of mine. There are more details beneath the video on the original web site APOD.

In short, if you ever wondered if it rains on the sun, the answer is yes. Just not rain, i.e., water. It’s actually extremely hot plasma. The example in this video happened in mid-July 2012 after an eruption on the Sun that produced both a Coronal Mass Ejection and a moderate solar flare.

“What was more unusual, however, was what happened next. Plasma in the nearby solar corona was imaged cooling and falling back, a phenomenon known as coronal rain. Because they are electrically charged, electrons, protons, and ions in the rain were gracefully channeled along existing magnetic loops near the Sun’s surface, making the scene appear as a surreal three-dimensional sourceless waterfall. The resulting surprisingly-serene spectacle is shown in ultraviolet light and highlights matter glowing at a temperature of about 50,000 Kelvin. Each second in the above time lapse video takes about 6 minutes in real time, so that the entire coronal rain sequence lasted about 10 hours.”

I’m not a scientist, but this is very “cool” to watch.
