The web-based Google Sky is now open to the public, very cool!

Google Sky includes a number of different ways to explore the universe. The initial view shows the visible universe and is a mosaic of images from the Sloan Digital Sky Survey, the Digitized Sky Survey and the Hubble Space Telescope. Select the thumbnail images at the bottom of the display to bring up the planets, the constellations, highlights from the Hubble Space Telescope, famous stars, galaxies and nebulae, views of the universe in the x-ray, ultraviolet and infrared and podcasts about upcoming astronomical events from Earth and Sky  Podcasts. Other items available through Google Sky:

  • Infrared – An infrared view of the sky from the Infrared Astronomical Satellite (IRAS). Change the transparency of this layer by moving the slide bar to blend the optical and infrared.
  • Microwave – A view of the microwave sky from NASA’s Wilkinson Microwave Anisotropy Probe (WMAP), which shows the universe as it was 380,000 years after the big bang.
  • Historical – The sky as drawn by Giovanni Maria Cassini (printed in 1792) showing the constellations in their classical form from the collections of David Rumsey
