By combining images taken almost simultaneously from the Ahead and Behind STEREO spacecraft, researchers have generated a 3-D sequence of four images that track an active solar region over about a one-week period (April 29 through May 5). The images were all taken in the 171 Angstrom wavelength of extreme ultraviolet light. Active regions, which are areas of intense magnetic activity, appear brighter in UV light. The region is seen moving from left to right as the Sun's rotation carries it along. Arcing loops above the active region reveal million-degree Celsius particles spinning along magnetic field lines.
These images can be viewed with red and cyan 3-D paper glasses.
