Visit http://science.nasa.gov/science-news/science-at-nasa/2011/02mar_spotlesssun/ for the full story. When solar activity recently plunged into a century-class minimum, many experts were puzzled. Now a group of researchers say they have cracked the mystery of the missing sunspots.
Visit http://science.nasa.gov/ for breaking science news. Something unexpected is happening on the sun. 2013 is supposed to be the year of Solar Max, but solar activity is much lower than expected. At least one leading forecaster expects the sun to rebound with a double-peaked maximum later this year.

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.
