astroengine writes: Astronomers have spotted a Jupiter-mass exoplanet happily orbiting the primary star of a binary system 49 light-years from Earth. "Inrakluk" is a rarity as only a few exoplanets have ever been found inside binary systems. It is theorized that the planet-building material would normally be flung out of the young binary star system, hindering the development of planets. But as the existence of Inrakluk proves, stable exoplanets are possible in binary star systems, throwing the leading planetary formation theory into doubt. The researchers have yet to find Tatooine (although, according to the comments at the bottom of the article, they are currently looking for a candidate that may resemble the fictional Star Wars world).
