Planet Declared As 100% Likely To Have Life... Now Can't Even Be Found

from the oops dept

You may recall a few weeks ago, we wrote about the discovery of the first "potentially life-sustaining planet" outside of our solar system, which got some astronomers so excited that one declared the chance of life on the planet to be 100%. Of course, he may want to adjust his optimism a bit downwards as Slashdot points us to the news that another group of astronomers are saying they can't find any trace of the planet:
But at this week's Astrophysics of Planetary Systems meeting, astronomer Francesco Pepe of the Geneva Observatory and the Swiss group reported that he and his colleagues could find no reliable sign of a fifth planet in Gliese 581's habitable zone. They used only their own observations, but they expanded their published data set from what the U.S. group included in its analysis to a length of 6.5 years and 180 measurements. "We do not see any evidence for a fifth planet ... as announced by Vogt et al.," Pepe wrote Science in an e-mail from the meeting. On the other hand, "we can't prove there is no fifth planet." No one yet has the required precision in their observations to prove the absence of such a small exoplanet, he notes.

Astronomer Paul Butler, a member of the U.S. team who is at the Carnegie Institution for Science in Washington, D.C., says he can't comment on the Swiss work because he wasn't at the meeting and the data are unpublished. He notes, however, that more observations will likely be needed to solidify the existence of Gliese 581g. "I would expect that on the time scale of a year or two this should be settled."
So, perhaps before we declare it 100% likely to have life, we should make sure it actually exists.

    Re: Re: Re:

    Now you're just trying to provoke me. And you're still thinking of God in human terms. Which is a common, understandable mistake, but one you should try to stop making. He isn't human, after all, so why should we think of him from that perspective? He's nothing like us. At all.

    If you have something constructive to say, fine, but otherwise lay off the venom. It doesn't make you look good, only afraid to see a perspective other than your own. And I haven't seen you back up anything you've said. Unlike me, which I have. The PDFs have hundreds of references in them, from Christian and secular scientists and their findings.
