this is our sun, our star.

this is our sun, our star.   this is what it does.

over 5 days last week, our sun spun and spewed out coronal mass ejections (no, this is not a dirty space news post!), sending waves of solar particles out into space, through our solar system.  the video was produced by NASA Goddard and shows solar flares and coronal mass ejections from Oct 23-28th.  the images were taken by NASA's solar dynamics observatory and the ESA/NASA solar and heliospheric observatory.

i particularly like how at 1:45 they show just how far out the solar particles are flung - notice the tiny little sun in the centre for scale!
