NASA's Solar Terrestrial Relations Observatory (STEREO) satellites have provided the first three-dimensional images of the sun.
VIDEO DESCRIPTION:
STEREO was able to capture bright loops in exquisite detail as they were arcing above an active region (May 26, 2007) over an 18 hour period. What you are actually seeing are charged particles spinning along magnetic field lines that extend above the Sun's surface. Active regions are areas of intense magnetic activity and often the source of solar storms. The video ends with a flourish in which a small coronal massection (CME) blows out into space.
PHOTO DESCRIPTION:
Below are additional images which show a mosaic of the extreme ultraviolet images from STEREO's Telescope taken March 17-27, 2007 and their 3-D counterpart.

false color images show the sun's atmospheres at a range of different temperatures. Blue image: 1 million degrees C, green, 1.5 million C, red 60,000-80,000, and yellow image 2.5 million C.
Each temperature allows scientists to focus on different features of the sun
