Galactic Map

Nasa has posted the most accurate face-on map of our galaxy yet, including new discoveries such as the "Far 3 Kiloparsec Arm". The galaxy was previously thought to have four arms, but the latest survey from the orbiting Spitzer telescope reveals that the galaxy is two armed bar spiral. Darth Mojo has an entertaining piece on the Spitzer data including a picture of how big an iPhone would have to be to display all the data at once!

I guess the old Karl Sims Panspermia video must show the genesis of life in a different galaxy, I always thought it was ours.
