Here Comes the Sun

If you don’t like cool stuff, then you can stop reading. But if you’re a fan of astronomical awesomeness, you need to watch the following video from NASA’s Solar Dynamics Observatory. NASA released the video in celebration of the SDO’s first five years of operation.

Andy Stout helps to explain what you’re about to see:

The SDO observes the sun in different wavelengths – and therefore different temperatures – to examine how material courses through the corona, all of which it is hoped will provide further clues as to what causes eruptions on the sun and why its magnetic fields are in constant, violent flux. Whatever the underlying causes though, the resulting titanic destruction and mayhem is balletically beautiful.
