Google Sky

Google Earth has just released an update, and it’s of galactic proportions.

They’ve added the ability to look from the centre of the earth toward the heavens – now you can check out start, nebulae, constellations and more. Very cool, especially if you don’t own a whacking great big telescope (or you want to check the northern hemisphere’s stars).

There's information (and screenshots) of it at Ogle Earth.
