Solar tsunamis are real, says NASA

Up until now the powerful waves of plasma observed on the surface of the sun known as "solar tsunamis" were thought to be the result of an optical illusion but NASA scientists have since been able to confirm that they are in fact real.
Incredibly powerful waves of plasma rippling across the surface of the sun and dubbed "solar tsunamis" were first observed years ago, but were thought to be an optical illusion. Scientists have now confirmed, though, that they are really real.When scientists first saw the phenomenon, it was hard to believe that a towering wave of hot plasma was actually racing along the sun's surface.One of the waves rose up higher than the diameter of Earth and rippled out from a central point in a circular pattern millions of miles wide, like a gargantuan pattern of waves created by a pebble dropped in a pond.Skeptical observers suggested it might be a shadow of some kind – a trick of the eye. But new observations from NASA's STEREO (Solar Terrestrial Relations Observatory) spacecraft are telling researchers that this controversial phenomenon isn't an illusion.

I was glad a video was posted along with the article. Although amazing, I wouldn't call it a solar tsunami per say. It appeared more like an explosive burst than anything else, but I concur since I'm not part of the research team.

I saw a documentary where they talked about these tsunamis but they never mentioned these waves were illutions. I guess they were right, I dont feel surprised about that.
