Rogue planet with mystical aurora discovered drifting beyond our solar system

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.

Dr Melodie Kao, an astronomer at Arizona State University said as per a report by Independent, "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".

Nevertheless, we still can't figure out how brown dwarf stars get auroras, considering they're nowhere near any type of stellar winds. Similar to the Northern Lights, this planet and some brown dwarves are known to have auroras of their own - despite lacking the solar winds that are known to drive them.

Auroras on Earth are created when charged particles from the Sun interact with Earth's magnetic field.

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.

However, recent VLA observations have uncovered that SIMP J01365663+0933473 is too lightweight to be a brown dwarf.

A massive glowing "rogue" planetary-mass object has been discovered, surprising scientists with not only its size, but also the fact it's not orbiting a star. Astronomers say the rogue planet is located 20 light-years from Earth and is about 200 million years old - which, in the grand scheme of things, is considered young for a planet.

It also boasts scorching surface temperatures of around 1,500 degrees Fahrenheit.

One measure used by astronomers is the mass of an object when deuterium - an isotope of hydrogen - stops fusing in the object's core.

Simultaneously, the Caltech team that originally detected its radio emission in 2016 had observed it again in a new study at even higher radio frequencies and confirmed that its magnetic field was even stronger than first measured.

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

SIMP0136 was originally discovered in 2006 by another team of researchers, led by University of Montréal astronomer Dr. Étienne Artigau. This meant that the object was a free-floating planet.
