Tatooine World’s Moon Could Potentially Host Alien Life
Link: Tatooine World’s Moon Could Potentially Host Alien Life
Life probably doesn’t exist on one of the most famous exoplanets, the gas giant Kepler-16b, which like Star Wars’ Tatooine orbits two stars. But a potential moon orbiting this planet might be a good place to search for ET.
Kepler-16b is a Saturn-sized planet 200 light-years away that orbits a pair of stars with about two-thirds and one-fifth the mass of the sun, respectively. Yet with no solid surface to stand on, the planet seems unlikely to have any creatures on it watching the spectacular view of a double sunset.
