A Solar Tsunami

In 2006, a large solar flare from an Earth-sized sunspot produced this tsunami-like shock wave. The resulting shock wave, technically called a Moreton wave, compressed and heated up gasses including hydrogen in the photosphere of the Sun, causing it to glow more brightly. These images were taken by the Optical Solar Patrol Network (OSPAN) telescope in New Mexico. The tsunami moved at nearly a million kilometers per hour, circling Sun in a matter of minutes.
