------------------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.
Not only do they say it's "possible," but the claim in the video is binary stars may outnumber single ones, like our own sun.
I wonder if Copernicus' equivalent had to double his efforts amid idiots twice as convinced "the world" was the center of the universe, 1.6 ~ gigabillion light years from here.
