Massive rogue planet with mystical aurora found drifting outside solar system

A rogue planet, over 12 times bigger than that the largest planet in the solar system, Jupiter, and not attached to any star, was discovered to be drifting alone through space not very far away from Earth.The planet is the first object of its kind to be found using a radio telescope. But more than its unnatural path across the universe, its mass and powerful magnetic strength (which is 200 times that of Jupiter) are baffling scientists."This object is right at the boundary between a planet and a brown dwarf, or ‘failed star', and is giving us some surprises that can potentially help us understand magnetic processes on both stars and planets," The Sun quoted Melodie Kao, the lead author of the study at Arizona State University, as saying.[caption id="attachment_4571131" align="alignnone" width="1280"]

The cause for auroras are yet to be explained, but their strong magnetic fields might hold clues."This particular object is exciting because studying its magnetic dynamo mechanisms can give us new insights on how the same type of mechanisms can operate in extrasolar planets – planets beyond our solar system," the report quoted Kao as saying. “We think these mechanisms can work not only in brown dwarfs, but also in both gas giant and terrestrial planets,” she said.Their research was published in The Astrophysical Journal.
