Discover the cosmos. Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. If Google Talk is installed on your system, you can share the sheer beauty of our universe with your friends. If neither Google Talk is available nor any friends are online, the service and its button are unavailable. With eye candy, transparency, and smooth animations for your viewing pleasure. This version is the first release on CNET Download.com.
