World Wide Telescope

WorldWide Telescope, launched late Monday, was developed by Microsoft's research arm.

It knits together images from the Hubble Space Telescope, the Chandra X-Ray Observatory Center, the Sloan Digital Sky Survey and others.

Computer users can browse through the galaxy on their own or take guided tours of different outer-space destinations developed by astronomers and academics.
