The Los Angeles Times has this cool story. Excerpts:
Astronomers have put the known universe in a box on your computer screen — the 120 million light-years of it within our grasp, at least.
With a mellifluous French-accented narration, some light piano music and sweeping computer animation, the video could become a stoner classic. It also happens to be the most detailed modern cosmography of all that is visible in the sky — and a great deal of what is not.
