SOLAR MINIMUM DEEPENS: The sun has been without sunspots for 32 of the past 33 days. To find a similar stretch of blank suns, you have to go back to 2009 when the sun was experiencing the deepest solar minimum in a century. Solar minimum has returned, bringing extra cosmic rays, long-lasting holes in the sun's atmosphere, and strangely pink auroras. Free: Aurora alerts*
A QUIET DAY ON THE SUN: Solar minimum has arrived, but even the "quiet sun" is an awesome thing. Powered by fusion, the sun is a 1027-ton nuclear explosion contained in one place only by the powerful force of its own gravity.*
