Massive glowing 'rogue' planet spotted 'drifting' in space

"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", Kao said.

A possible "rogue" planetary-mass over 12 times more massive than Jupiter has been found drifting alone through space around 20 light years away from Earth.

The planet is thought to be 200 million years old and is 20 light-years from Earth.

A brown dwarf is an object too large to be a planet, but isn't big enough to sustain the nuclear fusion of hydrogen in its core that is typical of stars. Researchers believe that SIMP, which has magnetic field 200 times more powerful than Jupiter's, may also have a moon or other planet as its particle source.

The astronomers mentioned that the planet's magnetic field is 200 times stronger than that of Jupiter and most probably this is the reason why it was detected by the National Science Foundation's Karl G. Jansky Very Large Array (VLA), a large radio telescope in New Mexico. Scientists aren't exactly sure how the auroras form in brown dwarfs, but they do have some theories.

Astronomers have discovered a rogue planet that's nearly too big to be considered a planet - and to top it off, the rogue object is a magnetic powerhouse. Its young age meant that it was in fact so much less massive that it could be a free-floating planet.

How the sunless planet has such strong auroras, similar to those seen in our own Solar System's giant planets, remains a mystery.

Astronomers have discovered a massive planet with a odd glow just outside the solar system, where it is just drifting without any kind of orbit. After being determined to be much younger and smaller than initially thought, SIMP may be classified as a planet, and not a brown dwarf.

This limit is around 13 Jupiter masses, so at 12.7 the newly identified planet was brushing right up against it.

"[This presents] huge challenges to our understanding of the dynamo mechanism that produces the magnetic fields in brown dwarfs and exoplanets and helps drive the auroras we see", said Gregg Hallinan, study co-author and assistant professor of astronomy at the California Institute of Astronomy, in a statement.

The so-called "rogue" planet does not revolve around a star, but instead rotates around the galactic center in interstellar space.

The first of such astronomical bodies was observed in 1995 and the scientists are still trying to understand more about the radio emissions and magnetic fields of five brown dwarves.
