SPACE PHOTOS THIS WEEK: Star Birth, Active Sun, More

December 25, 2009--Five regions of magnetic activity create bright blemishes on the sun on December 22 as seen in an ultraviolet image from the Solar and Heliospheric Observatory (SOHO). Two of the regions correspond to dark sunspots when the sun is seen in visible light.

This is the first time in 2009 that the orbiting probe has captured so much concurrent action on the sun. It's possible that the upswing will signal an end to the sun's unusually long quiet period, SOHO scientists say.
