Moreton Wave (A Tsunami On The Sun)

How cool is this!?

This imagery is shown on Astronomy Picture of the Day and titled, A Large Tsunami Shock Wave on the Sun.

According to the site,

"The rampaging tsunami took out some active filaments on the Sun, although many re-established themselves later. The solar tsunami spread at nearly one million kilometers per hour, and circled the entire Sun in a matter of minutes."
