Jupiter-Size Alien World Is Biggest 'Tatooine' Planet with 2 Suns Ever Found

A newfound alien world is the biggest ever discovered that has two suns in its sky, like Luke Skywalker's home planet of Tatooine in the "Star Wars" universe. Whereas the fictional Tatooine is a small and rocky world, however, the real-life Kepler-1647b is a gas giant about the size and mass of Jupiter. Kepler-1647b is a gas giant, so it doesn't have a surface — but any moons circling the huge planet could conceivably be capable of supporting life as we know it, study team members said.
