Video of the Day: A Big Blast

This giant coronal mass ejection took place on April 16, 2012. an M1 class (medium-sized) flare occurred at the same time, peaking at 1:45 PM EDT.

Today’s video of the day appeals to the astronomy wonk in all of us:  a huge blast of plasma exploding off the surface of the sun yesterday, April 16.  In this video, the blast is shown in profile as it erupts from the area of a large sun spot, blowing particles hundreds of thousands of miles into space in the blink of an eye.  Don’t worry, the thing wasn’t aimed at us.

NASA’s video shows the same ejection in various spectral frequencies.


From the notes on NASA’s YouTube page where we found this gem:

A beautiful prominence eruption producing a coronal mass ejection (CME) shot off the east limb (left side) of the sun on April 16, 2012. Such eruptions are often associated with solar flares, and in this case an M1 class (medium-sized) flare occurred at the same time, peaking at 1:45 PM EDT. The CME was not aimed toward Earth.
