Google Sky: Traveling to the stars has never been easier

 Google Sky ! To help you explore the far reaches of our universe, we have teamed up with astronomers at some of the largest observatories in the world to bring you a new view of the sky. Using Google Maps this tool provides an exciting way to browse and explore the universe. You can find the positions of the planets and constellations on the sky and even watching the birth of distant galaxies as seen by the Hubble Space Telescope.
We are particularly excited about the ability to view the universe at different wavelengths, to see how it would look if our eyes worked in the x-rays or infrared. As you explore these new layers, play with the transparency to blend between the different wavelengths and see how different parts of the universe light up at different wavelengths" About Google Sky & FAQs 

If you are interested in what's happening on the sky tonight or over the next few months then check out the podcasts from Earth and Sky or search for the position of your favorite planet.

"Google Sky can be used in a multitude of ways. Users can download Sky in Google Earth, use the program from their web browser, or download the app for an Android phone, which enables them to point their mobile phone toward the sky to identify objects. In terms of functionality, the program has an able search function (of course) and uses some (but not all) of the features of Google Earth. For example, this program does not allow for tilting of the view. But Google Sky can make use of some of the add-on features from the Google Earth Gallery. A fascinating (and addicting) tool that will serve serious scientists as well as students at all levels. Summing Up: Highly recommended. All levels/libraries. -- P. J.
