A team of Brazilian astronomers recently determined a giant exoplanet, over thirteen times more massive than Jupiter, is likely responsible for some funky orbital observations of a far away half-dead binary system. How it got there remains a mystery, but the scientists have some interesting theories.

KIC 10544976 – or ‘the place where a big ass planet got discovered’ as we like to call it – is a binary system (comprised of two stars) considered to be ‘evolved.’ Another way of putting it is that they’re old. They’re so old, in fact, that one of them is actually a white dwarf – a star that’s spent all of its nuclear energy. This means the massive planet is likely one of the more mature ones scientists have ever encountered.
