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.

    The use of the mass extinction link should not be thrown about so carelessly. Our youth are convinced that the end of the world will be in their lifetime and that is have a greatly negative impact on society as a whole.The very idea of a possible mass extinction induces panic. Research, theorize, discover...but do it responsibly!

    Every few years this pops up, regardless of a lack of perturbation of any observed planetary orbits or observed cloud of displaced objects.
    Every few years, it gets shelved, as not fitting observed facts.
    And it rears its ugly head again, typically with a new name.
    That all said, it IS good to keep looking. If the cyclic hypothetical planet still isn't found, they always DO find something ELSE new.

      Finally, a comment based on logic and historical facts. Thank you, Wzrd1. I do remember reading about "Nemesis" years ago. Nothing was proven, but they did make other discoveries as a result of that search for answers, so it wasn't a total waste of time. We'll wait and see what comes of this study of "Tyche." Meanwhile, the comments here from the lunatic fringe provide much entertainment.

    Hey everyone could this be the infamous large bodied object that is causing the major storms around the world.
    and headed toward us in 2012 passing between the sun and earth better known as planet X. The possibility
    of the crossing is very interesting to me. As you know NASA with the help of IRAS in 1984 found a large object
    that appeared to be on cycle and seems to be approaching us. Also the Vatican church has also employed a 6 million plus dollar scope on Mt. Graham in the desert of Arizona to track large objects in the sky. Things are getting more interesting as race toward 2012 and beyond.

      No. This couldn't be that. This is out in the Oort Cloud, and would have to achieve a significant fraction of the speed of light (the inner shell of the Oort Cloud is hypothesized to be about a light-year away from the Sun) to get here by then. Since it's a planet or a star, not an alien spacecraft, that's not likely. Also, anything that massive passing that close to the inner solar system would do a LOT more than mess with weather. It'd throw planets into the Sun or out of the solar system. Thus it's orbit can't take it anywhere near us, or we wouldn't be here today to study it.

  11. the dude

    To believe or disbelieve in a god or gods doesn't preclude a belief in science. If we take it that a god exists then there's no reason to automatically trash science. For me at least. I don't understand why people need to be so closed minded about it all. If I can explain something 2 ways it doesn't necessarily mean that one of them is wrong. If I say that God created the universe then why can't I say that it works a certain way also?

    If we use the analogy of a computer programmer: The programmer writes the source code and executes that code within a system. That program written within it will behave using the rules and processes defined. If that program is 'sentient' then that program will begin to search out the ways and means within itself and learn about the system it is running in. Simply because it does so doesn't disprove the existence of the programmer. It just means that the program understands pieces of its own coding.

    I'm not arguing for or against a god or 'programmer' I'm just saying that to me at least there's no reason to deny a god simply because we can explain a bit of how our universe works. I never understood the distinction there. Seems like a narrow view of it just for the sake of argument.

      The essential "problem" here is that it's scientifically impossible to disprove the existence of god. Or anything, for that matter. It's called a negative proof. Not possible. It's also generally impossible to "prove" anything scientifically, "proof" is a term that only applies to pure mathematics. Science is about evidence, and when enough evidence is gathered to support a "theory" then it is considered to be "true". Further evidence is always sought, and it is possible for a single piece of evidence to overturn what is considered "truth". This seldom happens any more as we acquire more data about the world, but scientists have very "open minds", as long as you provide them with evidence.

      Dr. Who,
      Cause and effect is a fundamental principle of our universe, however theorists talking about multiverse possibilities (i.e. alternate universes) note that nothing fundamental to our universe is necessarily similarly fundamental outside it, and that includes cause and effect. Thus if God created the universe, and thus exists outside of the universe, He doesn't necessarily follow cause and effect. Or time, for that matter. Or space.

      You are correct that science can't prove anything, but you're wrong that it can't disprove anything. The problem is that ideas like God and the invisible pink unicorns aren't scientific theories, because they aren't testable. A scientific theory can be tested, and thus disproven. God can't.

      Dr. Who, there's so much we don't understand. We don't understand infinitey, or quantum mechanics, or wave particle duality. We can do the math, we know it exists but we don't understand it. So just pointing out a paradox does not make the paradox a fallacy. I'm an Agnostic and I find Atheists to be just as close minded and illogical as religious zealots.

      By the same token you dont dismiss science just because it doesnt tally with what a book tells you.
      And you certainly don't start claiming magical forces must have done it just because science cannot explain something at this time.

      C Smith: But you're using the "P" word, "Proof". How could you prove that there are no invisible pink unicorns? I'm not sure how you'd demonstrate that they DO exist either, being invisible and all. But the burden is on the shoulders of the beleivers of IPU's to present their evidence.
      Seems to me that being untestable doesn't remove a "theory" from the realm of science. The concept that there are multiple universes is being given serious consideration, but it is at the present time untestable. It may remain that way forever, or somebody may come up with something someday. We'll just have to wait and see.
      Oh, and thanks for above kudos. Maybe I'll chime in here more often. You may not like it. Don't get me going on oil and energy...

    There is as yet no firm evidence that this object, or anything like it, even exists. This data is very prelimary. Much more research and measurement-taking needs to be done before we know anything "for sure". These two "researchers" are jumping the gun, as is the media. Shocking!!
