A Large Tsunami Shock Wave on the Sun

NASA APOD
COSMIC MESSAGE

The Sun can generate tsunamis, but they are waves of superheated gas, not water. This image captures a Moreton wave, a type of shock wave, spreading across the Sun's surface after a solar flare. It compresses and heats hydrogen gas in the photosphere as it travels.
