This image shows a gas giant planet circling the two red dwarf stars in the system OGLE-2007-BLG-349, located 8 000 light-years away. The planet - with a mass similar to Saturn - orbits the two stars at a distance of roughly 480 million kilometres. The two red dwarf stars are a mere 11 million kilometres apart
