Wicked Coronal Mass Ejection

So there was a gigantic explosion on the Sun the other day:

First of all: good gravy that is beautiful.

These cooled filaments (this one half a million miles long) are masses of charged particles held in place by the Sun's magnetic field.  The Coronal Mass Ejection you see takes about an hour, and is traveling at 900 meters per second (about 2000 miles per hour).

Here's pictures at four different wavelengths (all in the X-Ray spectrum):

The variety of wavelengths helps scientists watch the change and distribution of temperature.

Even though it was directed away from us, the blast expands spherically, so we did catch some of the ejection about four days later, resulting in even more beauty, as charged particles smash into the Earth's atmosphere and emit Bremsstrahlung ('braking') radiation:

It's enough to make you think there might be something slightly dangerous about a slow, fiery nuclear explosion the size of 100,000 Earths.
