Just Released - WorldWide Telescope

Microsoft Corp. has launched its answer to Google Sky: a free, web-based program for zooming around the universe from any internet-connected computer. Developed by Microsoft’s research arm, the WorldWide Telescope—which debuted in May—knits together images from the Hubble Space Telescope, the Chandra X-Ray Observatory Center, the Sloan Digital Sky Survey, and other labs. Computer users can browse through the galaxy on their own or take guided tours of different outer-space destinations developed by astronomers and academics. The site lets users choose from a number of different telescopes and switch between different light wavelengths.
