Hey, amateur astronomers: good news! A vast array of astronomical data is now just a mouse click away, thanks to a new online interactive astronomy visualization software program from Microsoft Research called the Worldwide Telescope (WWT).

Per the company's Website, the WWT "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."

It really is an impressive collection of astronomical data amassed by the Hubble Space Telescope, the Chandra X-Ray Observatory, the Sloan Digital Sky Survey, and other powerful instruments.
