anthemaniac writes: Thirty years ago, Luke Skywalker saw what scientists are just now realizing, that double sunsets are likely common in the universe. Astronomers have long known that binary star systems are common. And models suggested that planets could form in these systems, even though there's a double-tug of gravity on the material that would have to form a planet. Observations from NASA's Spitzer telescope, show that binary systems are just as likely to be surrounded by planet-forming debris disks are are lone stars.
