Exoplanet orbits two stars

A newly-discovered exoplanet, BEBOP-1c, orbits twin suns–another example of a phenomenon once considered impossible. Binary stars are common, but "Tatooine" worlds, named for the well-sunned homeworld of Luke Skywalker in Star Wars, were only recently discovered.

"Circumbinary planets were originally thought not to exist, since the binary stars stir up the planet-forming disks, creating a harsh environment for planets to form," study lead author Matthew Standing, an astrophysicist at the Open University in England, told Space.com.
