Astrophysicists at the University of Oklahoma, using a technique called microlensing, have confirmed the existence of exoplanets beyond our own Milky Way galaxy. The scientific team has discovered not just one or two, but an estimated multitude of planets which range in size form the Moon to Jupiter. OU professor Xinyu Dai said, "We are very excited about this discovery. This is the first time anyone has discovered planets outside our galaxy. These small planets are the best candidate for the signature we observed in this study using the microlensing technique.” OU researcher Eduardo Guerras said, "This is an example of how powerful the techniques of analysis of extragalactic microlensing can be."
