WorldWide Telescope is a new project from Microsoft Research that combines imagery of space and celestial objects into one easy-to-use interface. From the site's overview page: "The WorldWide Telescope (WWT) is a environment that enables your computer to function as a virtual telescope--bringing together imagery from the world's best ground- and space-based telescopes for the exploration of the universe."
This image is a high-resolution image of Abell 1689, a galaxy cluster in the constellation Virgo, as taken by the Chandra X-Ray Observatory. The image is embedded on the digitized sky that is the basis of WorldWide Telescope.
