    Hah and it happens just when I was thinking of wimps, dark matter, neutrinos and Neptune! Ok I digress ...

    Yeah that's it. They called it Kepler-19c. They found it by gravitational influence it has on Kepler-19b. They know it exists but not much else. They don't even know its brightness and I don't even talk about its mass and composition. We just can't see it. I wonder how it looks like.

    That reminds me of Neptune. People didn't know about Neptune (back in the day), they predicted its existence by irregularities in the orbit of neighboring Uranus. Very interesting method. I've read about this few days ago.

    Well deserved bump

    Another unseen planet has been revealed:

    Amazing discovery. Just like it happened before with Kepler-19c.

    The spacing and timing are crucial:

    Dr. David Nesvorny who led this research explains:

    Lol anyone remember what Yoda said? Go to the center of gravity's pull and find your planet, you will, Hmmm. Ok I digress ...


    I wish them luck :)

    how could they say they find it when the planet is invisible?
    planet is an object, so it should be seen, has size
    but if it aint seen, it could be anything, dark energy, big meteorit or UFO spaceship in cloak mode maybe
    they even aint see it at all
    but it still interesting

    invisible in this context means it doesnt pass in front of its star, so we can't see the star dim, so we can't see the planet.

    imagine a line from us to the star, we keep looking at the star to see its brightness change, if the "invisible" planet's orbit never takes it between us and the star we will never see it

    If someone knocks on your door and runs away what would you think of? Was it some alien, a bear, Elvis, a lolcat or maybe it was just some prankish kid?

    In many cases knowledge/experience and logics become more important than evidence.

    alien doesn't know the custom of knocking, the bear can't knock with his paws, elvis is dead or you would hear the people sing kumbaya outside, the lolcat can't escape teh internetz

    W1zz is probably from that planet and is working hard to keep it secret and invisible to us Earthlings.

    Immediately I'd say it was the lolcat.. For sure..
    But good stuff.. Maybe one day we'll find a planet, we actually go to..lol

    Cool! As observing/detecting tech improves/matures we will definately find more & more out "there" :)

    I'm curious as to the composistion?

    Maybe planet b is just going through a patch of space where time slows down.

    Newfound exoplanet may turn to dust

    Another object found:

    But they think it is a planet, not a comet.

    That's a long and most painful way to die ...

    Yup another two new planets: Kepler-36b and Kepler-36c. They are orbiting a star in the Cygnus constellation referred to as Kepler-36a.

    It's always great to know about the new worlds.

    They used photometer (to measure light from distant celestial objects) and applied an algorithm called quasi-periodic pulse detection.

    Researchers said that the transit time pattern for the large planet and the transit time pattern for the smaller planet are mirror images of one another. Interesting ....

    Ok now about composition and other properties:

    For everyone who still cares:

    This is really exciting. This newfound exoplanet Gliese 581g is the most Earth-like planet ever known.

    Amazing :eek:

    That's interesting.
    BUT, Gliese 581 is a red dwarf so the system is probably bathed in relatively high amounts of ionizing radiation. Red dwarf stars tend to be flare stars. If that is the case then it's probably not a very friendly place for biological life, as we know it.

    does it have a moon? if i remember correctly without a stabilizing moon its tidal behavior can be quite cataclysmic and its axial range will be larger creatign diverse climates
