NASA: 'Star Wars'-Type Double Sunset Might Be Possible
The double sunset that Luke Skywalker gazed upon in the film "Star Wars" might not be a fantasy. Now playing at http://www.jpl.nasa.gov/videos/spitzer/spitzer20070329/ is a video comparing the double sunsets of the "Star Wars" planet, Tatooine, with recent findings by NASA's Spitzer Space Telescope. The telescope found signs that planetary systems around double stars are at least as common as they are in single-star systems like ours. This suggests the universe could be packed with planets that have two suns. Sunsets on some of those worlds would resemble the ones on Tatooine. -- Ronn! :) ___ http://www.mccmedia.com/mailman/listinfo/brin-l

The sunset which was pictured in the movie owes it's appearance to the athmosphere. To form auch an athmosphere some requirements concerning the planet's climate have to be met. This is quite unlikely for planets in multi start systems. However, if someone gets the UFOs from the Roswell incidents going, one might send a team of Industrial Light & Magic to such a planet. They'll can do it. Heck, they managed to get the double sunset even on earth!
