A massive "rogue" planet with an unexplained "glow" has been seen drifting alone through space, scientists claim.
The planet, which is 12 times as large as Jupiter, sits around 20 light years away from Earth.
The rogue planet is the first object of its kind to be spotted using a radio telescope, according to the National Radio Astronomy Observatory.

Both its mass and the enormous strength of its magnetic field, which is more than 200 times stronger than Jupiter's, challenge what scientists know about the variety of astronomical objects found in the depths of space.
