Sun Lets Off Huge Burp

Technically, this massive eruption on the surface of the sun—which might have kicked up as much as a billion tons of "material"—is a flare. But it looks more like an enormous solar burp, doesn't it? And, wow, it's big, huh? Dr. C. Alex Young of the Goddard Spaceflight Center, who narrates the video above, says he's never seen a flare as "spectacular" as this one before.
