Project Transit Search: Planet Hunting

Posted by Hemos on from the looking-for-our-new-home dept.

An anonymous reader writes "During the nights of Oct. 5 and Oct. 30, backyard sky-watchers will get their chance. Univ. California (St. Cruz) and NASA are enlisting the large amateur astronomy community to use CCD-equipped telescopes and computer-analyzed photographs to find dimming in the only star (HD 209458 b, HD is the Henry Draper star catalog) known to have a planet candidate correctly aligned for the 'transit method' of planet discovery."

  1. *BSD is dying (FP) by Anonymous Coward · · Score: -1, Offtopic
    It is official; Netcraft now confirms: *BSD is dying

    One more crippling bombshell hit the already beleaguered *BSD community when IDC confirmed that *BSD market share has dropped yet again, now down to less than a fraction of 1 percent of all servers. Coming on the heels of a recent Netcraft survey which plainly states that *BSD has lost more market share, this news serves to reinforce what we've known all along. *BSD is collapsing in complete disarray, as fittingly exemplified by failing dead last [samag.com] in the recent Sys Admin comprehensive networking test.

    You don't need to be a Kreskin [amazingkreskin.com] to predict *BSD's future. The hand writing is on the wall: *BSD faces a bleak future. In fact there won't be any future at all for *BSD because *BSD is dying. Things are looking very bad for *BSD. As many of us are already aware, *BSD continues to lose market share. Red ink flows like a river of blood.

    FreeBSD is the most endangered of them all, having lost 93% of its core developers. The sudden and unpleasant departures of long time FreeBSD developers Jordan Hubbard and Mike Smith only serve to underscore the point more clearly. There can no longer be any doubt: FreeBSD is dying.

    Let's keep to the facts and look at the numbers.

    OpenBSD leader Theo states that there are 7000 users of OpenBSD. How many users of NetBSD are there? Let's see. The number of OpenBSD versus NetBSD posts on Usenet is roughly in ratio of 5 to 1. Therefore there are about 7000/5 = 1400 NetBSD users. BSD/OS posts on Usenet are about half of the volume of NetBSD posts. Therefore there are about 700 users of BSD/OS. A recent article put FreeBSD at about 80 percent of the *BSD market. Therefore there are (7000+1400+700)*4 = 36400 FreeBSD users. This is consistent with the number of FreeBSD Usenet posts.

    Due to the troubles of Walnut Creek, abysmal sales and so on, FreeBSD went out of business and was taken over by BSDI who sell another troubled OS. Now BSDI is also dead, its corpse turned over to yet another charnel house.

    All major surveys show that *BSD has steadily declined in market share. *BSD is very sick and its long term survival prospects are very dim. If *BSD is to survive at all it will be among OS dilettante dabblers. *BSD continues to decay. Nothing short of a miracle could save it at this point in time. For all practical purposes, *BSD is dead.

    Fact: *BSD is dying

      Although it's true that the first date has already passed, the second night, October 30, is still a few weeks away.

      I am looking forward to what the results of this are, although I'm betting on a ton of false positives--after all, what sort of people do you expect to be looking in the sky for more planets? It's to be expected that some of them might be overeager to "see" planets that aren't there--the anal probes that aliens plant in abductees are known to make them delusional.

      This is probably not a big issue, because the discovery is not done at the whim of the amateur, but rather at the discration of a relatively complicated piece of software.

      And of course interesting results will be scrutinized by more sophisticated equipment.

    This is amazing! 10 years ago, the experts had no proof that planets existed outside of our solar system; today an amateur with an 8" telescope and a CCD camera can help study them. I love to see technology being put to good use like this.

    I remember when announced they discovered of the first extrasolar planet in 1995. I felt really jealous that some guy who got to work a massive telescope was the one who found it. I thought it was a shame that astronomy was "out of the hands" of the amateur. I'm glad I was wrong.

    Here is a link to a page that has a nice overview of the history and procedures used to find extrasolar planets.

      For the most part, the major discoveries (with the exception of asteriods) are made by large telescopes. It's just a simple equation that more money = better equipment, and amateurs generally don't have the money to keep up with the new technology that's available.

    NIGHT!

    At the risk of being all too philospychodelic, it's interesting to note that (as has often been said) you need new instruments to make new astronomic discoveries (eg telescope for the moons of Jupiter, radio telescopes for the Big Bang).

    This thing about discovering new planets based on thought processes only a computer are capable of suggests that our brains just aren't capable of comprehending the universe.

    I guess the SETI project won't bear fruit until the robots have liberated themselves from us... heh heh good luck guys, no sex drive no luck
