Google Sky was formerly available only within the Google Earth software, but with the launch of the web version your browser can become a virtual telescope, zooming and panning across the cosmos.
- Powerful search that lets you browse tens of thousands of named objects.
- Three optical sky surveys that show you what your naked eye would see if it had a really good zoom lens. Try switching to infrared, microwave, ultraviolet, or x-ray to see the sky in a completely different light. Or blend between these views to create unique visualizations on the fly.
- Galleries highlighting the best images from Hubble and many other telescopes.
- Current planet positions and constellations.
- Overlays of custom KML content. (Simply paste a Sky KML URL into the search box, just like on Google Maps.)
- Last but not least, the Earth & Sky podcasts gallery is not to be missed, particularly for those who run a classroom.
