Giant Planet Imaged Around Massive Star

Giant Planet Imaged Around Massive StarThis image shows the massive binary system known as b Centauri and its giant planet, b Centauri (AB)b. This is the first time astronomers have directly observed a planet orbiting a star pair this massive. The duo, which have a total mass of at least six Suns, is the bright object in the top left corner of the image. The bright and dark rings around it are imaging artifacts. The planet, visible as a bright dot in the lower right of the frame, is a super-Jupiter that orbits the pair at 560 a.u. The other bright dot in the image (top right) is a background star.ESO / Janson et al. Astronomers have imaged a giant planet around a massive pair of stars known as b Centauri. While Jupiter’s orbit around the Sun is five times wider than Earth’s, this plan...
