Bizarre Rogue 'Planet' with Incredible Auroras Puzzles Scientists

Astronomers find rogue planet dozen times more massive than Jupiter

Researchers are working to explain the presence of a mysterious large object floating outside the solar system that may be a rogue planet, RT reported.

Brown dwarfs are objects too massive to be considered planets, yet not massive enough to sustain nuclear fusion of hydrogen in their cores - the process that powers stars.

Another team looking at the brown dwarf data, discovered an object called SIMP J01365663+0933473, to be far younger than the others.

At 200 million years old and 20 light-years from Earth, the object has a surface temperature of about 825 degrees Celsius, or more than 1500 degrees Fahrenheit. The object is about 13 times heavier that Jupiter, and doesn't appear to orbit a parent star.

The monstrously large world is twelve times bigger than Jupiter and the first object of its kind to be spotted using a radio telescope, according to the National Radio Astronomy Observatory.

Kao led this study while a graduate student at California Institute of Technology (Caltech).

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

Originally detected in 2016, it was one of five brown dwarfs that astronomers studied using the VLA.

The observed magnetic field "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, of Caltech.

The unusual object sits in a grey area between a star and a planet, and was originally classed as a "brown dwarf" - a failed star.

The new planet is 12 times the size of Jupiter which has a radius of more than 69,000 kilometres.

She continued: "We think these mechanisms can work not only in brown dwarfs, but also in both gas giant and terrestrial planets". But since then, as our technology progressed, astronomers found that these stars also exhibit signs of magnetic activity, including the formation of powerful auroras - which on Earth are created by solar wind particles interacting with the planet's magnetic field. That's because spotting the dips in the star's brightness as the planet passes in front of it gives away its presence.

The team is particularly excited by the new research because it relies in part on radio observations of the object's auroras - which means that radio telescopes may be able to identify new planets by their auroras.
