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

In new research published in The Astrophysical Journal, scientists describe the massive object as one that's between a planet and a brown dwarf. The curious thing about this planet is not just its vast size but also the fact it doesn't appear to orbit any star.

Situated around 20 light-years from Earth, this object is likely a 200-million-year old planet that's very hot (1500 degrees Fahrenheit) and doesn't seem to follow any orbiting pattern.

According to experts, it is common for similar observations to be made on brown dwarfs, aborted stars with high mass to be considered as planets, but without enough to trigger nuclear fusion reactions and become stars.

"This. object is exciting because studying its magnetic dynamo mechanisms can give us new insights on how the same type of mechanisms can operate in planets beyond our solar system", Kao said. In terms of physical traits, it's slightly bigger than Jupiter, the largest planet of our stellar neighborhood, but weighs 12 times more than the gas-giant. For comparison, the Sun has a surface temperature of 5,500 degrees Celsius or nearly 10,000 degrees Fahrenheit.

Brown dwarfs were predicted to exist all the way in the 1960s, but the first one was only discovered in 1995, confirming the initial theories.

A rogue planet with 12 times the mass of Jupiter with dancing auroras has been discovered just outside our solar system, a new study says.

Located in New Mexico, at an altitude of 6,969 ft, Karl G. Jansky's Very Large Array (VLA) is a radio telescope that is part of the National Radio Astronomy Observatory network.

This finding could help to better understand the magnetic processes of stars and planets, Kao believes.

Discovered in 2016, the planet named SIMP J01365663+0933473, or SIMP for short, was originally thought to be a brown dwarf planet, or dying star.

The auroras on our planet are caused by its magnetic field interacting with the solar wind (the continuous flow of charged particles from the sun's upper atmosphere, known as the corona, that permeates the solar system).

Brown dwarf masses are notoriously hard to measure, and at the time, the object was thought to be an old and much more massive brown dwarf.

Researchers at the National Radio Astronomy Observatory have detected the first exoplanet using a radio-telescope, which is big, very hot, and has a powerful magnetic field.
