Rock and Roll Sun

This video is a must see- from NASA's Solar Dynamics Observatory.  You can watch it over and over and each time you will see more and more activity on the Sun...simply amazing!

According to the SDO group:

"Over the past 24 hours we have seen some beautiful solar events. None of them have a direct impact on Earth, but they are astonishing to watch. It just shows how an active Star our Sun really is. Far from boring. 

On December 8, 2011 a twisting prominence eruption occurred on the lower eastern limb. The view through the AIA 304 angstrom filter shows us this beautiful eruption.

In the early hours of December 9, 2011 SDO observed a little bit of a different eclipse. An erupting cloud of plasma was eclipsed by a dark magnetic filament. The eruption is still on the far side of the Sun, behind the eastern limb and is slowly moving forward and over the limb sometime next week.

In front you can observe the filament of relatively cool dark material floating across the Sun's surface in the foreground. That filament partially blocks the view of the hot plasma eruption behind it."

Make sure your speakers are on for the full rock concerto....
