Only a few short years after Pluto lost its planet status, schoolchildren may have to learn a whole new planet. Scientists said Thursday that, indeed, one had been discovered just outside the Milky Way—and that it’s the first of its kind. The planet, called HIP 13044b, and its parent star, HIP 13044, formed outside our galaxy and were “captured” by the Milky Way some six billion years ago, according to Space.com. HIP 13044b’s composition may be radically different from the other planets discovered in the Milky Way, according to National Geographic, and some scientists even said that the lack of heavy metals proved the planet should never have been born at all.
