Scientists, telescope hunt massive hidden object in space

You know how you sometimes can sense that something is present even though you can't see it? Well, astronomers are getting that feeling about a giant, hidden object in space.

And when we say giant, we mean GIANT.

Evidence is mounting that either a brown dwarf star or a gas giant planet is lurking at the outermost reaches of our solar system, far beyond Pluto. The theoretical object, dubbed Tyche, is estimated to be four times the size of Jupiter and 15,000 times farther from the sun than Earth, according to a story in the British paper The Independent.

Astrophysicists John Matese and Daniel Whitmire from the University of Louisiana at Lafayette think data from NASA's infrared space telescope WISE will confirm Tyche's existence and location within two years.

The presence of such a massive object in the solar system's far-flung Oort Cloud could explain a barrage of comets from an unexpected direction, according to a December article at

Its 27 million-year orbit could also explain a pattern of mass extinctions on Earth, scientists say.

Brown dwarfs are cold "failed" stars; their dimness and lack of heat radiation can make them hard to detect. Gas giants are huge planets - like Saturn, Jupiter and Neptune - that are made up of gases and may lack a solid surface like Earth's.

Whitmire told The Independent that Tyche will probably be composed of hydrogen and helium and have colorful spots, bands and clouds like Jupiter.

"You'd also expect it to have moons," he said. "All the outer planets have them."

Tyche was first hypothesized in 1984 as Nemesis, a dark companion star to the sun. It's been the subject of astronomical research and debate ever since. In July, another article said the celestial evidence suggests Tyche could not possibly exist.

To distinguish it from the Nemesis star theory, Matese and Whitmire are calling their object Tyche, after the good sister of the goddess Nemesis in Greek mythology.

Their research is published in Icarus, the International Journal of Solar System Studies.

    don't call it a brown dwarf. we prefer african-solarian little star.

    so does this mean that Tyche is going to fling a comet at us capable of extinction in 11 million years....

      Not at all. Tyche actually flung the comet at us half way through its previous orbit so it should be here....tomorrow.

    Great thing in life is WE the working sucker who is not related to the bildaburgs/rothchild/j.p morgan and a few several do not know anything in the system today,but welfare and losers. These ppl behind the scenes want you to be stupid and not learn so they can make there move(which will be soon)
    They will chip you and brainwash you just like hitler did by burning down his own whitehouse and blamed it terrorism. Now america has stole hitlers way to keep YOu the sheeple intact. Great job sheeple keep up the great work. I do feel for the war vets that lost lives from a government who pays other countries to go to war with them. I do hope the ppl of america finally realize and halt any votes just like egypt did. POwer is THE PPL NOT THE SHEEPLE(IF YOU DECIDE TO AGREE WITH A GOVERNMENT)

    good luck though, i will see you soon in this coming ww3 which starts in november of 2011.

      You believe you're "HUMAN"? that is what "THEY" want you to believe. Don't be a Shuman yourself! Wake up! That red stuff coursing through your "body" is spacefuel. If you pour it into a duck, you'll finally be broken of the chains our alien captors want you shackled to.

      See, it's easy to be a freakin' wierdo who makes no sense, so stop trying so hard!

      bildaburgs empire:

      I wish you luck in your 'obvious venture' of helping a nation. Your pessimistic view gets you no where. I suggest taking a more positive approach to directing the American citizens if you feel so passionate about them and their wrong doings... or maybe you don't offer positive suggestions because you're not smart enough to come up with any? You sound like a nagging house wife and your negative tone is just annoying to read.

    It's true. I've been there. And I brought back an unintelligent life form, more virus than anything. What a mistake THAT was, for it seems bent on destroying Earth.
    I called it "Non-sensicus brownturdicus"
    In the past 49 years it has morphed into a human form and has learned to procreate. I believe people on Earth have come to know it as "Obama"
    Sorry humanity, I guess I shoulda brought back the rock instead.

  11. Someone who learns

    Just so you guys know this planet has had cycles of extinctions...It wasnt just a couple of times with the dinosaurs...Just saying...Learn your facts and act accordingly. Of course they would start talking about this once its already too late. unless some one here has been building a spaceship to live in while it destroys

    A truthful scientist declares very VERY little as "impossible." Because most things can not be proven with 0% doubt as impossible. In fact, it is much easier to prove something as possible than impossible especially when talking about things that occur outside of our planet.

      True enough,but this type of speculation about a massive planet or very nearly dead Nemesis Star has been circling around for many years.In theory our sun has gravitational attraction to almost a thousand times Pluto's distance from the sun.It's just that a thorough search of the space out beyond Pluto has been inconclusive.When looking into scientific matters we should not be too positive of anything.Such a massive planetary body would be very difficult to find.
