    Incredibly powerful waves of plasma are rippling across the Sun's surface. These "solar tsunamis" were once thought to be an optical illusion. The first witnessed wave, taller than the Earth and creating a rippling pattern millions of kilometers around, was so amazing researchers thought they might be seeing some kind of flaw or trick in the satellite's vision instead of a real wave. The Solar Terrestrial Relations Observatory (STEREO) spacecraft were able to confirm the tsunamis existence.
