I chose the APOD blog "The extreme ultraviolet sun", because it's just so darn pretty! The photo, which appears strangely green and blue, was taken March 30th by the Solar Dynamics Observatory. The view traces the hot plasma at temperature approaching one million kelvins. The Solar Dynamics Observatory is able to send 1.5 terabytes of data back every day, which is apparently equivalent to half a million songs on an MP3. The photo is also in falls color. Preeeetty!
