Where Your Shadow Has Company

Explanation: Want to take a relaxing interstellar vacation ? Consider visiting Kepler-16b , a world in a binary star system. In fact Kepler-16b is the first discovered circumbinary planet . It was detected in a wide 229 day orbit around a close pair of cool, low-mass stars some 200 light-years away. The parent stars eclipse one another in their orbits, observed as a periodic dimming of starlight. But Kepler-16b itself was discovered by following the additional very slight dimming produced during its transits. Like sci-fi planet Tatooine of Star Wars fame, two suns would set over its horizon. Still, Kepler-16b is probably not a Tatooine-like terrestrial desert world. Instead, Kepler-16b is thought to be a cold, uninhabitable planet with about the mass of Saturn and a gaseous surface ... so plan to dress accordingly.
