Astronomers discover weird rogue planet glowing with auroras

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.

The so-called "rogue" planet does not revolve around a star, but instead rotates around the galactic center in interstellar space.

The planet is only around 20 light years from Earth, but it's not really doing much besides relaxing in the vastness of space.

The planet, which is 12 times as large as Jupiter, sits around 20 light years away from Earth.

Brown dwarfs, objects that are two massive be considered planets but not massive enough to sustain nuclear fusion in their cores, were first predicted in the 1960s and detected for the first time in 1995.

Team president Jerome Stoll added: " Renault made a decision to come back to Formula One to fight for world championships". So too was staying put at Red Bull , however, with the former champions switching from Renault to Honda power next season.

What's really special about that planet with the big long name is that it has a magnetic field 200 times stronger than even the mighty Jupiter.

Researchers have discovered a "rogue" planet outside of our solar system using the Very Large Array (VLA), the first time such a discovery has been made using a radio telescope. This finding is the first radio telescope finding of an object the mass of a planet found outside the Solar System.

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

"They [the surprises] can potentially help us understand magnetic processes on both stars and planets".

"Such a strong 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 Caltech astronomer Gregg Hallinan.

Urban Meyer says he failed on media day dealing with Zach Smith
At that point, Ohio State knew of at least two accusations of domestic violence against Smith. "In 2015, I came forward with it". However, Urban Meyer claims that he did not know about Zach Smith's abusive behavior until now, and fired him when he found out.

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

This limit is around 13 Jupiter masses, so at 12.7 the newly identified planet was brushing right up against it. Latest measurements have established that the exoplanet has a surface temperature of 825 degrees Celsius (around 1517 degrees Fahrenheit), shows the International Business Times.

She continued: "We think these mechanisms can work not only in brown dwarfs, but also in both gas giant and terrestrial planets".

In fact, Kao's team says the exoplanet even has auroras, which give off radio emissions that the VLA has managed to pick up.

The National Radio Astronomy Observatory is a facility of the National Science Foundation, operated under cooperative agreement by Associated Universities, Inc.
