Solar System Look-Alike Found

SpuriousLogic writes "Astronomers have discovered a planetary system orbiting a distant star which looks much like our own. They found two planets that were close matches for Jupiter and Saturn orbiting a star about half the size of our Sun. Martin Dominik, from St Andrews University in the UK, said the finding suggested systems like our own could be much more common than we thought."

    I'm sorry, I have trouble whenever whenever an astronomer suggests that something they found "may be much more common than we thought." One observation does not mean way more common. It jumps the gap from "purely theoretical" to "proven possible", and in the data set of the known universe really isn't enough to make any type of assertion about commonality.

    Yes, I know, our solar system makes it two.

      It certainly eliminates the "uniqueness" we thought our solar system was. So yes, 2 is more common than we previously thought.

      Right; we don't really have any data to confirm how common earthlike planets are. I expect they're very common, using the common-sense reasoning thusly: As soon as we gained the technology to detect big planets we found them all over. As soon as we develop the technology to detect small planets, the same thing will probably happen. I'm 99% positive I'm right.

      But scientists can't really reason that way; they may hypothesize smaller planets, but can't really make any factual statement about what lies beyond their ability to detect. I guess that the statement would be better phrased as we now have concrete evidence our solar system isn't unique, so the hypothesis that our type of system is relatively common has passed a hurdle of proof.

  4. 5,000 light years by mr_mischief · · Score: 3, Insightful

    ... "At least planetary systems like ours might be more common than previously thought over that direction, 5,000 years ago, at around the distance from us that light would take 5,000 years to get here. Or maybe somebody's holding up a distorted mirror 2,500 light years away. We're not really sure. Some scientist said we're discovering more than we used to, now that we're confident that we can detect them and bother looking. That must mean the spike in data is representative."

    I'm looking hopefully forward to giving people directions by system name and planet number just as much as the next /. geek. I doubt, though, that thinking in general about the number of multi-planet systems has changed drastically because of this one system. Like most science reporting in the mainstream press, this is oversimplified and overhyped.

  5. Impressive work by hattig · · Score: 4, Interesting

    I read the article earlier, and then it had that the star was 5 light years away. I investigated, and it is actually 4900 light years away.

    I'm impressed that they could resolve two planets going around a star that far away, gravitational lensing or not.

    FTA:

    He said that the ultimate goal for exoplanet researchers was to find habitable Earth-like and Mars-like planets. (emphasis added)

    While we all crack wise about the bizarro planet of our science fiction dreams, it bears pointing out that the point of the program is ostensibly to find other inhabitable planets--that is, potential sites for future human expansion, rather than other inhabited planets. The difference between the two is not insignificant, and is a nod to the somewhat conservative view that while it may prove impossible to find another planet like the Earth where life has evolved concurrently with our own, it is nevertheless very realistic to search for another planet like the Earth where life could thrive.
