This image provided by NASA Thursday Oct. 2, 2008 shows the "Cantaloupe ridges" on the sun. The glowing white magnetic network is what gives the sun its extra oblateness (The ratio of a planet's polar to its equatorial diameter) during times of high solar activity. Amateur astronomer Gary Palmer took the picture in July 2005 using a violet calcium-K filter.
