A young, free-floating world sits alone in space in this illustration. The object, called WISEA J114724.10−204021.3, is thought to be an exceptionally low-mass “brown dwarf,” which is a star that lacked enough mass to burn nuclear fuel and glow like a star.

They Finally admit the Caltech findings had truth to it, about the Ninth Planet.

NASA: Nibiru now named A.k.a WISEA 1147, floats freely throughout the galaxy, unattached to any star system or planetary structure.

In 2011, astronomers announced that our galaxy is likely teeming with free-floating planets. In fact, these lonely worlds, which sit quietly in the darkness of space without any companion planets or even a host sun, might outnumber stars in our Milky Way galaxy. The surprising discovery begged the question: Where did these objects come from? Are they planets that were ejected from solar systems, or are they actually light-weight stars called brown dwarfs that formed alone in space like stars?

A sky map taken by NASA's Wide-field Infrared Survey Explorer, or WISE, shows the location of the TW Hydrae family, or association, of stars, which lies about 175 light-years from Earth and is centered in the Hydra constellation. The stars are thought to have formed together around 10 million years ago. Recently, data from WISE and its predecessor, the Two Micron All Sky Survey, or 2MASS, found the lowest-mass free-floating object in this family -- a likely brown dwarf called WISEA J114724.10−204021.3.

A new study using data from NASA’s Wide-field Infrared Survey Explorer, WISE, and the Two Micron All Sky Survey, or 2MASS, provides new clues in this mystery of galactic proportions. Scientists have identified a free-floating, planetary-mass object within a young star family, called the TW Hydrae association. The newfound object, termed WISEA J114724.10−204021.3, or just WISEA 1147 for short, is estimated to be between roughly five to 10 times the mass of Jupiter.

WISEA 1147 is one of the few free-floating worlds where astronomers can begin to point to its likely origins as a brown dwarf and not a planet. Because the object was found to be a member of the TW Hydrae family of very young stars, astronomers know that it is also very young — only 10 million years old. And because planets require at least 10 million years to form, and probably longer to get themselves kicked out of a star system, WISEA 1147 is likely a brown dwarf. Brown dwarfs form like stars but lack the mass to fuse atoms at their cores and shine with starlight.

“With continued monitoring, it may be possible to trace the history of WISEA 1147 to confirm whether or not it formed in isolation,” said Adam Schneider of the University of Toledo in Ohio, lead author of a new study accepted for publication in The Astrophysical Journal.

Of the billions of possible free-floating worlds thought to populate our galaxy, some may be very low-mass brown dwarfs, while others may in fact be bona fide planets, kicked out of nascent solar systems. At this point, the fraction of each population remains unknown. Tracing the origins of free-floating worlds, and determining whether they are planets or brown dwarfs, is a difficult task, precisely because they are so isolated.

“We are at the beginning of what will become a hot field – trying to determine the nature of the free-floating population and how many are planets versus brown dwarfs,” said co-author Davy Kirkpatrick of NASA’s Infrared Processing and Analysis Center, or IPAC, at the California Institute of Technology in Pasadena.

Astronomers found WISEA 1147 by sifting through images taken of the entire sky by WISE, in 2010, and 2MASS, about a decade earlier. They were looking for nearby, young brown dwarfs. One way to tell if something lies nearby is to check to see if it’s moved significantly relative to other stars over time. The closer an object, the more it will appear to move against a backdrop of more distant stars. By analyzing data from both sky surveys taken about 10 years apart, the close objects jump out.

Finding low-mass objects and brown dwarfs is also well suited to WISE and 2MASS, both of which detect infrared light. Brown dwarfs aren’t bright enough to be seen with visible-light telescopes, but their heat signatures light up when viewed in infrared images.

The brown dwarf WISEA 1147 was brilliantly “red” in the 2MASS images (where the color red had been assigned to longer infrared wavelengths), which means that it’s dusty and young.

“The features on this one screamed out, ‘I’m a young brown dwarf,'” said Schneider.

After more analysis, the astronomers realized that this object belongs to the TW Hydrae association, which is about 150 light-years from Earth and only about 10 million years old. That makes WISEA 1147, with a mass between about five and 10 times that of Jupiter, one of the youngest and lowest-mass brown dwarfs ever found.

Interestingly, a second, very similar low-mass member of the TW Hydrae association was announced just days later (2MASS 1119-11) by a separate group led by Kendra Kellogg of Western University in Ontario, Canada.

Another reason that astronomers want to study these isolated worlds is that they resemble planets but are easier to study. Planets around other stars, called exoplanets, are barely perceptible next to their brilliant stars. By studying objects like WISEA 1147, which has no host star, astronomers can learn more about their compositions and weather patterns.

“We can understand exoplanets better by studying young and glowing low-mass brown dwarfs,” said Schneider. “Right now, we are in the exoplanet regime.”

Other authors of the study include: James Windsor and Michael Cushing of the University of Toledo; and Ned Wright of UCLA, who was also the principal investigator of the WISE mission.

NASA’s Jet Propulsion Laboratory in Pasadena, California, managed and operated WISE for NASA’s Science Mission Directorate in Washington. The spacecraft was put into hibernation mode in 2011, after it scanned the entire sky twice, completing its main objectives. In September 2013, WISE was reactivated, renamed NEOWISE and assigned a new mission to assist NASA’s efforts to identify potentially hazardous near-Earth objects.

The 2MASS mission was a joint effort between the California Institute of Technology, Pasadena; the University of Massachusetts, Amherst; and JPL. Caltech manages JPL for NASA.

WISE, NEOWISE and 2MASS data are archived at IPAC.

Hy🌟 thank you 😊 for that.No say he does bad things.they not.ok.That is God House.Ours Ancesters.and beutys the stars 🌃 and Angeles.i can see there souls🌟 Ancesters.want to now.what happened to then.its time for us to show the World the true💥 about then.they done so much for us.all they built for us.they want see all.the beutys from Stars.i want be with then.i now how they are.well.i really not care how they are.i love then so much.such dazeling love I need be with then.why I feel so much love for then.they my family.i feel they part of me.im.still surching for answers.and God always play 🎭 with me.they are all creations of god.massive beutys.want contact.with all of then.want to now how many different species.they are.i have same idea but I not now if I’m right .same I now I see.dame I not see but I feel there presence invisible.all so beutys

  2. Why is the label “ninth planet” being used when the planet in question isn’t even in our solar system? This reference specifies it as a part of our solar system. Did I miss something? The title of this article looks nonsensical since a “planet nine” by definition must be orbiting our sun in our solar system, and only by virtue of that, be “orbiting” our galaxy. Any planet that we would reasonably refer to as “planet nine” in the traditional sense (earth is the third planet) must be a part of our solar system.

    If the planet in question is not part of our solar system then it is misnamed and should be renamed to save confusion.

  3. Purely to follow up on tthe update off this
    matter oon our web pge and would really want to let you know
    simply how much I liked the time you took to publiush ths beneficial post.
    In the post, you actually spoke oof how to really handle this problem with all ease.
    It would be my pleasure to accumulate some more tips from your
    web site and coime up to offer some others whhat I have learned from you.
    Thank you for you usual good effort.
