A team of astrophysicists from the University of Oklahoma say they've discovered planets in a galaxy 3.8 billion light-years away. It's the first time any extragalactic planets have been found.

The scientists used a technique called microlensing — literally using the light-warping ability of an object's gravity to magnify even more distant objects. The planets are too far away to actually see but can be found using computer modeling.

Many of the planets the scientists found appear to be orphans, not bound to any star, and range in mass from that of our moon to that of Jupiter.
