Last month astronomers announced the first ever discovery of extrasolar planets… in another galaxy! We’ve already confirmed almost 4000 planets beyond our solar system, but these have all been in a single galaxy, the Milky Way. But then last month a serendipitous discovery opened the door to a galaxy 3.8 billion light years away and it turns out it’s home to thousands upon thousands of planets.
