This amazing video from NASA (via EarthSky) shows an incredibly gigantic eruption on the Sun's surface that produced three different types of events: a solar flare, a coronal mass ejection (CME), and a really interesting and rare phenomenon known as coronal rain.
Coronal rain occurs when hot plasma in the eruption cools and condenses then follows the outline of the normally invisible magnetic fields as it rains back to the Sun's chromosphere. I found that particularly amazing to see.
The images were gathered on July 19, 2012 by the Solar Dynamics Observatory’s AIA instrument. One frame was shot every 12 seconds over a span of 21.5 hours from 12:30 a.m. EDT to 10:00 p.m. EDT. The video plays at a rate of 30 frames per second, so each second equals 6 minutes of real time.
What's extra cool is when the scale of this thing is compared to the size of Earth. If you were feeling small earlier today, you should be feeling microscopic after watching this.
