It’s basically a virtual telescope that allows you to explore the deep sky, and some of the most interesting spots in the universe. You can opt for guided tours, conducted by astronomers or teachers, or check things out on your own. The imagery is compiled from a range of top space- and ground-based observatories, and the tools allow you to switch spectrum mid-stream, so you can see what certain regions or objects look like in different wavelengths. Check it out, and let us know how you think it stacks up to Google Sky. Via Yahoo News
