    A planet where its distance from its star (sun) is such that water is liquid.... Do you know what that means?

    I tested myself before opening the topic. My first guess was a Food additive then i thought, wait...i think thats a planet, i read about that recently and YES i was right!

    I find things like this interesting, thanks for posting the video.

    It means that when mankind gets there he'll be able to load up on water.

    It means that planets can exist in habitable zones. This is trivial, we just did not have much observational evidence until recently.

    That is all that it means, at this point.

    Mars for example, exists in this zone. Venus, with the right sort of atmosphere, would be another.

    We have no indications of water on the planet. Maybe future instruments will be able to do some sort of spectroscopic analysis.

    We dont know there is water but we do know that its distance from its star is the distance needed for water to be liquid.

    Only under appropriate gas pressures and temperatures. The moon is the same distance from the Sun as the Earth, you know. But if you held a bucket of water on the surface, it would boil off, even at normal room temperature.

    good point, thanks

    It'd be pretty cool if it does have water, though!

    Thanks for bringing this up, CJ!

    As BTS correctly pointed out concerning the possibility of liquid water, "Only under appropriate gas pressures and temperatures. The moon is the same distance from the Sun as the Earth, you know..."

    Ah, but the moon is SMALL and has no atmosphere...

    The pressures and temps are functions of gravity and atmosphere. Gliese 581g is about 3.7 earth masses in size, so it should have some kind of atmosphere. If the planet also has a magnetic field (caused by a liquid iron core), the atmosphere might be protected from the solar wind of it's red-dwarf - err, I mean LITTLE PERSON - mother star. This could be quite promising.

    Maybe new light will show that King Jesus is going to relocate the JWs to Gliese 581g, where pet dinosaurs await their arival!

    (Note to the Faithful and Discrete Slave of the WTB&TS: these ideas are copyrighted by me and the owner of this board here and now. You'll have to come up with your own whack-job new light.)

    Here's a bit of what wikipedia says about it: "an unconfirmed extrasolar planet, orbiting the red dwarf star Gliese 581, 20.5 light-years from Earth... It is the sixth planet discovered in the Gliese 581 planetary system and the fourth in order of increasing distance from the star. The discovery was announced by the Lick-Carnegie Exoplanet Survey in late September 2010, after a decade of observation.

    Studies indicate the planet is situated near the middle of the habitable zone of its parent star, where temperatures are neither too hot nor too cold. If it is a rocky planet, favorable atmospheric conditions could permit the presence of liquid water, a necessity for all known life, on its surface. With a mass 3.1 to 4.3 times Earth's, Gliese 581 g is considered a super-Earth, and is the planet closest in size to Earth known in a habitable zone. This makes it the most Earth-like Goldilocks planet found outside the Solar System and the exoplanet with the greatest recognized potential for harboring life.
