NASA discovers 6 brown dwarf stars 9 to 40 light-years from our Sun

August 24, 2011SPACE – Scientists using data from NASA’s Wide-field Infrared Survey Explorer (WISE) have discovered six “Y dwarfs”– star-like bodies with temperatures as cool as the human body. This artist’s conception illustrates what a “Y dwarf” might look like. Y dwarfs are the coldest star-like bodies known, with temperatures that can be even cooler than the human body. Astronomers hunted these dark orbs for more than a decade without success. When viewed with a visible-light telescope, they are nearly impossible to see. WISE’s infrared vision allowed the telescope to finally spot the faint glow of a half dozen Y dwarfs relatively close to our sun, within a distance of about 40 light-years. “WISE scanned the entire sky for these and other objects, and was able to spot their feeble light with its highly sensitive infrared vision,” says Jon Morse, Astrophysics Division director at NASA Headquarters in Washington. The Y’s are the coldest members of the brown dwarf family. Brown dwarfs are sometimes referred to as “failed” stars. They are too low in mass to fuse atoms at their cores and thus don’t burn with the fires that keep stars like our sun shining steadily for billions of years. Instead, these objects cool and fade with time, until what little light they do emit is at infrared wavelengths. The atmospheres of brown dwarfs are similar to those of gas giant planets like Jupiter, but they are easier to observe because they are alone in space, away from the blinding light of a parent star. So far, WISE data have revealed 100 new brown dwarfs.  Of these, six are classified as cool Y’s. One of the Y dwarfs, called WISE 1828+2650, is the record holder for the coldest brown dwarf with an estimated atmospheric temperature cooler than room temperature, or less than 80 degrees Fahrenheit (25 degrees Celsius). The Y dwarfs are in our sun’s neighborhood, from approximately nine to 40 light-years away. The Y dwarf approximately nine light-years away, WISE 1541-2250, may become the seventh closest star system, bumping Ross 154 back to eighth. By comparison, the star closest to our solar system, Proxima Centauri, is about four light-years away. “Finding brown dwarfs near our Sun is like discovering there’s a hidden house on your block that you didn’t know about,” says Michael Cushing, a WISE team member at JPL. “It’s thrilling to me to know we’ve got neighbors out there yet to be discovered. With WISE, we may even find a brown dwarf closer to us than our closest known star.” –NASA

    Maybe I am being cynical, but I find it suspect that amateur you tubers have been using WISE to track Ele (planet x, the destroyer, Nemesis, Nibiru, wormwood–whatever a person calls it) yet NASA has just discovered using WISE to see a “brown dwarf”?

    I also find this comet suspect as well…”With WISE, we may even find a brown dwarf closer to us than our closest known star.” Almost sounds as though this is a doorway to use explaining what may (or may not be), headed toward earth this fall.

    So hard to tell with all the disinformation!

      ‘Officially’, there is no ‘Nemisis’.

      However, there is an object called ‘Tyche’ by astronomers.

      It’s like two opposite sides, of the same coin.
      Wasn’t Nemesis, the twin of Tyche, in mythology ??

      Yeh this to me sounds like a failed attempt at softening the blow of what were all thinking.
      Oh guess what… We’ve found one headed right for us they’ll be telling us the next discoverer of a brown dwarf will be called Elle Nin.


    • i agree about the disinfo its freakin ridiculous! There is something coming and it seems like this is their way to set the stage for disclosure about an incoming dwarf star. A lot of people think its haarp or scalar, but if that is the case, then we are equally in trouble.

    Since I was a teen-ager…in other words…many years ago…I have read from many sources there was life beyond the stars. When I was a child, I would look up to speak with God, and I could almost feel the breathing of the clouds as each made their way throughout the space above! I re-call questioning….Is there someone there looling dowm at me, other than the angels, that are dear love-ones now gone to the heavens. Maybe someday when I leave this earth, I will go to another world with human habitation and then on to be with my Lord and love-ones. Now … look at this…,,,NASA DISCOVERS 6 BROWN DRAWF STARS 9 TO 40 LIGHT-YEARS FROM OUR SUN!!! How magnificent! Read all and carefully go over the last two sentences. “IT’S THRILLING TO ME TO KNOW WE’VE GOT NEIGHBORS OUT THERE YET TO BE DISCOVERED. WITH WISE, WE MAY EVEN FIND A BROWN DWARF CLOSER TO US THAN OUR CLOSEST KNOWN STAR.” See….how many more years will it be before life is actually discovered? MAYBE WITHIN MY LIFETIME….if not…IT IS COMING! Hats off to Nasa & associates for their endless endeavors to shake hands with our outer space….IT WILL COME! Just my thoughts and how I feel about this majestic comprehensive detection within our heavens! Enjoy the read….Peggy Inez, Author & Storyteller

    There was a quake up North on the rift of 5.3 about an hour ago, just followed by a 4.4 aftershock. The North Atlantic plate is ticklish these days…

    Ohh look, its a bird ,its a plane ,its a …dwarf? …..A bunch of liars trying to cover their as#* when the disinformation they have been spreading is proven to be utter crap, keep up the lies NASA the truth you have been hiding for the last 50 years is about to make it’s apperance.


  6. Pia Amato says:

    I personally believe like many other EP followers, that NASA is hiding something from the public. Their actions this year alone prove that. They have shut down several deep space telescopes, including WISE, which is linked on this news story to finding these new dwarf stars. WISE was shut down without any explanation on 2-17-11. Interestingly enough, The Guardian in the UK posted on 2-14-11 about a new planet that was discovered by WISE. Why would NASA shut down a brand new telescope that can see behind all of the space dust with new infared technology?


  7. Mis Tery says:

    I think people fail to think about the fact that we are in a solar system rotating around a central galactic sun. As we rotate, we move into other areas of the galaxy that contains other stars and planets and that has an effect on our sun as well as us. Of course there’s other life. The agenda has always been to prepare the people for it. Just look at all the movies this year and last. When they make themselves visible when it’s time, the people will be too scared because of all the propaganda to accept their help.

    “With WISE, we may even find a brown dwarf closer to us than our closest known star”

    Erm…isn’t our closest known star the Sun?!


    • The article was referring to the nearest star to our Sun not Earth which is Proxima Centauri which is a little over 4 light-years from Earth. Brown Dwarf stars for the most part are in fixed orbits, unless that have been ejected out of a star system upon its formation. But let’s put this in perspective, the closest Brown Dwarfs discovered were 9 light years from Earth. Light travels at speeds of 300,000 km per second or 186,000 miles an hour. That means an object has to travel at the speed of light to reach Earth in 9 years, which is first, impossible by the laws of relativity which governs the operation of energy, mass and velocity. Most objects move through space at the speed of a snail in comparison to light – at a speed of between 30 and 50 km per second, including planets and comets. It takes comets an average of about 7.4 months to move the distance from Jupiter to Earth.


      • idiotbox says:

        The word “discovered” needs to be redefined as “admitted”. The thing that gets me is certain individuals among us don’t seem to have a problem accepting information from a government that has been caught lying to it’s people and the world, those that perpetrate those lies are no less guilty than those who created them.


      • Levi S. says:

        Fascinating indeed and light travels very fast and there are things in outer space that do travel very very fast. A quasar for example. Quasars emit nearly the entire EM spectrum, so, the speed of light. The most powerful ones operate at energies measured in TeV. They also emit charged particles that have been accelerated by supermassive black holes to near the speed of light. It’s called a “Gamma-Ray” burst and it is discharged by a quasar and travels through space at the speed of light. But as far as comets, asteroids and things like that go, then yes, they travel pretty slow in the cosmic levels of speed.

    Interesting choice of words. I just watched a video on YT the other day with a NASA (Never a Straight Answer) physicist swearing up and down that there is no brown dwarfs in our midst. Now all this talk about new brown dwarfs being discovered? Quote “It’s thrilling to me to know we’ve got neighbors out there yet to be discovered. With WISE, we may even find a brown dwarf closer to us than our closest known star.” Sounds like they are preparing us for a surprise discovery of one of these bad boys in our solar system. Quote “Y dwarfs are the coldest star-like bodies known, with temperatures that can be even cooler than the human body”. Sound pretty hospitable for life to me! Quote ““Finding brown dwarfs near our Sun is like discovering there’s a hidden house on your block that you didn’t know about,”. A house? Does someone live there? I might have chosen tumble weed as an analogy. Small and pretty unnoticeable unless your looking. And whats all this mention of “Near our Sun”. Can anyone even comprehend what 1 light year is let alone 40 of them? I think not. Most people can’t even fathom the distance between earth and the sun. 1 AU or 93 000 000 miles. So to say that a brown dwarf could be near our sun is a misuse of words and implying that its actually NEAR OUR SUN or close enough that the gravitational fields are interacting with one another. Just my first impression of this article. Nasa bores me with their lame discoveries. Cheers.

    Thanks for the post on brown dwarfs and Y dwarfs! This site collects an amazing list of interesting phenomena and altho it attracts its fair share of conspiracy theorists, people with religiosity problems, and some who are challenged in a variety of ways, I do appeciate what you have done.


  11. Personally, I think this was a pretty interesting article. Now, this is not saying that I believe it, but it is interesting. (Yes, I have my doubts.)

    Thank you Alvin for the wide variety of topics you cover on this site. I love reading the comment section also, with the varying opinions and arguments. I always enjoy reading intelligent blogs and comments that are respectful and keep me thinking.

    Be blessed everyone and Maranatha
