Mysterious Rogue Planet Detected Outside Solar System

There Is an Absolutely Gigantic Rogue Planet Wandering Our Galactic Neighbourhood

Mysterious 'rogue' planet spotted outside solar system

And we know this because astronomers have detected it using the Very Large Array radio telescope. This first of its kind object is around 20 light years away from Earth.

Scientists have made the first radio-telescope detection of a huge free-floating planet beyond our solar system, a new study said. It's a massive 200 times the strength of Jupiter's magnetic field.

"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.

According to a working definition laid out by the IAU Working Group on Extrasolar Planets, a brown dwarf as an object that is too small to produce hydrogen fusion, the dominant process that generates energy in stars, but is still large enough for deuterium fusion, a lower temperature process vital to newly forming stars.

A rogue planet more than 12 times the size of Jupiter (artist's impression pictured) has been spotted hurling through space.

Initially believed to be a brown dwarf star, the peculiar celestial object, boasting a suite of unusual physical traits, turned out to be a planet after all.

NASCAR CEO and Chairman Brian France was arrested and charged with DUI early Monday in NY , according to a report from TMZ . NASCAR says it takes France's arrest "as a serious matter and will issue a statement after we have all of the facts".

Planets are normally attached to a host star which gives it energy and light. Since the mass of a Brown dwarf is hard to accurately calculate, at the time, the object found was thought to be an old, massive brown dwarf. They say the new world is 200 million years old and 20 light-years from Earth. Latest measurements have established that the exoplanet has a surface temperature of 825 degrees Celsius (around 1517 degrees Fahrenheit), shows the International Business Times.

"When it was announced that SIMP0136 had a mass near the deuterium-burning limit, I had just finished analyzing its newest VLA data", Dr. Kao said. Scientists theorise that one possibility is having a planet or moon interact with the dwarf's magnetic field.

Such a strong magnetic field could improve our understanding of dynamo mechanism.

A mysterious large object is floating around outside our solar system and researchers aren't sure exactly what it is - although it could be a rogue planet.

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

The first of such astronomical bodies was observed in 1995 and the scientists are still trying to understand more about the radio emissions and magnetic fields of five brown dwarves. They are reporting their findings in the Astrophysical Journal. It is a component of the National Radio Astronomy Observatory (NRAO).
