Solar Eruption Today!



The Solar & Heliospheric Observatory (SOHO) project satellite captured this dazzling, hypnotic footage of a solar eruption yesterday.

SOHO is a joint effort between the European Space Agency (ESA) and NASA; its purpose, besides capturing incredible images like the one above, is "to study the internal structure of the Sun, its extensive outer atmosphere and the origin of the solar wind, the stream of highly ionized gas that blows continuously outward through the Solar System."

There was a super solar filament a week or so ago. I wonder if that collapsed to trigger this explosion. There's some chatter about it being a Cavendish event, but I cannot find any information regarding the energies involved in this event.

It looks big, though.

The speed is still, of course, very fast by human standards, but not so fast as you might think seeing an animation which is compressing about eight hours into around four seconds.
