An Amazing CME Erupts from the Sun Captured August 31, 2012 by NASA's Solar Dynamics Observatory NASA Goddard Space Flight Center via Flickr
We’ve covered some pretty amazing coronal mass ejections (CMEs) here on PopSci, but we might have to crown this one the best yet. Blasting forth from the solar surface at 900 miles per second on August 31, it was captured in all of its tendril-esque glory by NASA’s Solar Dynamics Observatory (SDO). If the image doesn’t look real, rest assured that it is. But the SDO clearly doesn’t capture imagery of the sun in the same way the human eye does. This image is a blended version of the 304 and 171 angstrom wavelengths. I couldn’t begin to tell you why those are the proper wavelengths to capture this sort of thing, but I will endorse the choice. This is one magnificent image of our local star. Oh, and though you would’ve heard about it by now if this particular CME posed any threat to the home planet, you can also rest assure it does not. It was not directed toward Earth, though it was close; it interfered with our magnetosphere enough to cause auroras to appear on the night of September 3. Which is as close as you want a solar eruption like this to get.

Holy crap that's real?

Looks like the sun is ready to go 'boom' and supernovae ha.

Thank goodness our sun is ten times too small to perform that feat. But you never know maybe someday it will college with a bigger start and merge and then go boom?

What is the noise seen in the blue and green part of the vid?

@gizmowiz, if another star, or body large enough, was to collide, or even come close to our sun, the damage it would do to our orbits alone would kill us all before the star could ever go super nova. if for some reason the sun gained significantly more mass our orbit would be pulled tighter to the sun effectively roasting us.
