It looks like its possible Earth might have a Tatooine-esque twin sun thing going on for a few weeks. Betelgeuse (the star not the ghost played by Michael Keaton) is has been losing mass rapidly lately causing Astronomers to believe its close to a supernova anytime between now and early 2012 (or in a million years as per the article). Don't worry, scientists believe the impending explosion will only shower the Earth with mostly light (possibly bright enough to not have a proper nighttime for a few weeks) and harmless neutrinos.
