Last night Google rolled out its latest mapping application, which allows you to browse the night sky and zoom in on nearby galaxies and stars. Called Google Sky, it’s just about the most fun I’ve had with a mapping application since . . . well, Google Earth. But unlike Earth, Sky doesn’t require you to download a bunch of software. You can browse the heavens as easily as you browse your neighborhood on Google Maps. And there are no annoying little pushpins — only helpful information boxes about what astronomical objects you’re gawking at. You won’t be able to look away. [Google Sky]
