Visit for more! With a burst of solar flares and Northern Lights, the sun is waking up from a three-year slumber.
Sunspots have fascinated mankind right from their first detection. Their mere existence challenged science and philosophy when it was recognized that the sun, once believed to be pure and unchanging, was indeed not. Now, state-of-the art telescopes, combined with the muscle of a supercomputer called "Bluefire," are allowing scientists to come to a physics understanding of sunspots and to accurately model their structure and dynamics.
