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

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

It's very large, and has an extremely strong magnetic field, and it's a "rogue", not attached to any other object. As a result, they wander alone through space.

Rogue planets are hard to identify because these objects travel through space without any parent star and do not emit any kind of light. A light year is equal to about 6 trillion miles.

She said that SIMP "is giving us some surprises that can potentially help us understand magnetic processes on both stars and planets". Nicknamed "failed stars", brown dwarfs are larger than planets, but not quite large enough to fuse hydrogen, the way stars do.

The odd object, called SIMP J01365663+0933473, has a magnetic field which is more than 200 times stronger than the magnetic field field of Jupiter, according to the study published in The Astrophysical Journal Supplement Series.

The object is one of five supposed brown dwarfs located by the Very Large Array (VLA) radio telescope in New Mexico in 2016. 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. Further observations revealed that brown dwarfs can generate strong auroras.

At 12.7 times more massive than Jupiter, it's right on the upper limit for planets - verging into brown dwarf territory.

An unaccompanied brown dwarf like SIMP JO1365663+0933473, the object detected by the VLA, does not have a companion star and thus is not flying through a solar wind. By comparison, the Sun's surface temperature is about 5,500 degrees Celsius.

"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". It is a component of the National Radio Astronomy Observatory (NRAO).

"When it was announced that SIMP J01365663+0933473 had a mass near the deuterium-burning limit, I had just finished analyzing its newest VLA data", said Kao.

Studies that followed it demonstrated that certain brown dwarfs display strong auroras, similar to the ones seen in the Solar System's giant planets.

Zeroing in on this new find could lead to new techniques being developed to help search for alien worlds.
