This is fucking marvelous. An entire hemisphere of the sun explodes which then ignites another region. According to io9, this was an event previously thought impossible:
In this ultraviolet light video taken by NASA, you can watch a phenomenon that scientists didn’t believe could exist until a few months ago. An entire hemisphere of the sun explodes, one region igniting another. What does this discovery mean?
It turns out that the sun doesn’t just spurt out gouts of gas in isolated spots. In fact, our star’s magnetic field brings many regions of Sol’s surface into direct relationships with each other, so areas separated by millions of miles can literally spark each other up. The results are called “sympathetic flares.”
G’damn amazing. Hit the jump to watch the explosion in action.
