View Sky from your browser through google sky

Google Earth is used, for the most part, for looking at the roof of your house and trying to work out when the photo was taken. However, there's no such killer app for Google Sky (with the exception perhaps for Mork, Marvin the Martian and ET) which means you're just going to have to use it for purely scientific purposes. It's that much easier now that you can access it direct from your browser, rather than the Google Earth app which you previously needed to have downloaded. It shows you a variety of views, including microwave and infrared as well as from different sources like the Hubble telescope. You can even view the stars that make up each constellation or view the planets in the solar system.
