Amateur Astronomers May Have Found Ninth Planet

Scientists may have uncovered a new planet at the edge of our solar system thanks to the help of some amateur astronomers.
Astronomers suspect there's a ninth planet orbiting our sun beyond Neptune. Yes, ninth. (Sorry, Pluto lovers.) Now they're trying to pinpoint it.
The search started last year when astronomers at Caltech noticed some peculiar orbits from some outer space objects beyond Pluto. "We realized the only way we could get them to all swing in one direction is if there's a massive planet also very distant in the solar system keeping them in place," Caltech astronomy professor Mike Brown said.

Thanks to some very committed volunteers, researchers may have found it — or at least a few different celestial bodies that could be the mysterious Planet Nine.
21,000 Volunteers looked at over 100,000 images to try to find tiny objects moving against a backdrop of motionless stars.
