Well Microsoft had to go one better than Google's Earth and bring you the whole universe! I've just been watching an amazing video from the TED Talks website. It's about the new WorldWide Telescope that Microsoft will be launching in the Spring of this year. This will enable web users to explore the universe in close up detail by drawing on imagery from a whole range of the world's most powerful telescopes.
The images and capabilities being described on the video look really amazing. Well worth a watch!
Hope you enjoy it. Really looking forward to getting to use this.
