"This object is right at the boundary between a planet and a brown dwarf, or 'failed star, ' and is giving us some surprises", said Melodie Kao, who led a recent study while a graduate student at Caltech.
The object was originally detected in 2016 as one of five brown dwarfs the scientists studied with the VLA to gain new knowledge about magnetic fields and the mechanisms by which some of the coolest such objects can produce strong radio emission.
Astronomers discovered a planet just beyond our solar system with many mysterious characteristics. This massive rogue planet does not seem to be attached to any star and it is the first such object to be discovered so far using a radio telescope.More news: First round of United States tariffs on Chinese goods to hit $50B - USTR
Artist's conception of SIMP J01365663 0933473, an object with 12.7 times the mass of Jupiter, but a magnetic field 200 times more powerful than Jupiter's. It was initially thought to be much larger and much older, but the new study has found that the object (called SIMP J01365663+0933473) is "only" 200 million years old. Brown dwarf planets are sometimes called "failed stars" because they're almost large enough for fusion to begin taking place in their core, but that's not even the most unique thing about this particular planet.
The temperature on its surface is more than 1,500 degrees Fahrenheit. The first ever sighting of a Brown Dwarf happened as late as 1995. They have detected a possible "rogue" planetary-mass object.
Simultaneously, Dr. Kao's team observed SIMP0136 in a new study at even higher radio frequencies and confirmed that its magnetic field was even stronger than first measured - more than 200 times stronger than Jupiter's.
Auroras on Earth are created when charged particles from the Sun interact with Earth's magnetic field. Scientists theorise that one possibility is having a planet or moon interact with the dwarf's magnetic field.More news: Texas student includes 14-foot long gator in graduation photos
Kao added, "We think these mechanisms can work not only in brown dwarfs, but also in both gas giant and terrestrial planets".
The rogue planet along with some brown dwarves are known to have their own auroras, similar to the aurora borealis or the northern lights seen on Earth.
The so-called "rogue" planet does not revolve around a star, but instead rotates around the galactic center in interstellar space.More news: OH race too close to call but Trump claims victory
