[HD] NASA Reveals the Entire Sun for the 1st time

Launched in October 2006, STEREO traces the flow of energy and matter from the sun to Earth. It also provides unique and revolutionary views of the sun-Earth system. STEREO has given us the first view of the entire sun on February 6, 2011 and when coupled with SDO, will give us complete views of the sun's entire surface and atmosphere for the next 8 years.
