Scientists using a radio-telescope array have spotted a gigantic roaming cosmic body with an abnormally strong magnetic field.

The object is one of five supposed brown dwarfs located by the Very Large Array (VLA) radio telescope in New Mexico in 2016. Brown dwarfs are failed stars—objects much larger than most planets but too small to sustain fusion reactions.
