What is Google Sky?
Google Sky is a part of the Google Earth application and allows users to omnisciently explore the universe with a computer connected to the internet. It’s like a personal planetarium. Google Sky, which was announced on 22 Aug 2007, now contains several images of the radio sky made using NRAO instruments. We invite you to Download NRAO Radio Skymarks to your own desktop, and explore the invisible Universe interactively!
