In long exposures made with great telescopes, the edge-on spiral galaxy NGC 891 looks like a flying saucer pitching sharply through a city of suns. The galaxy's supernatural appearance was naturally befitting for the television series The Outer Limits, which fathered the vast science-fiction genre we enjoy today. In size and mass NGC 891 is comparable to our own Milky Way. Its rotational velocities - the orbital speeds of stars, gas, and dust around the galaxy's core - are also very similar to those in our galaxy.
