Newly Spotted Comet May Shine Among Brightest In History 100

Posted by timothy

Reader intellitech points to an article at National Geographic, from which he excerpts: "If astronomers' early predictions hold true, the holidays next year may hold a glowing gift for stargazers—a superbright comet, just discovered streaking near Saturn. Even with powerful telescopes, comet 2012 S1 (ISON) is now just a faint glow in the constellation Cancer. But the ball of ice and rocks might become visible to the naked eye for a few months in late 2013 and early 2014—perhaps outshining the moon, astronomers say. The comet is already remarkably bright, given how far it is from the sun, astronomer Raminder Singh Samra said. What's more, 2012 S1 seems to be following the path of the Great Comet of 1680, considered one of the most spectacular ever seen from Earth."

      That's fair enough, science hasn't changed since 1973. I believe that history will ultimately show that the decline of science started with the break-up of The Doors [wikipedia.org], though others contend that it was the rise of The Butts Band [wikipedia.org]. Still others mark 1973 as the beginning of the end of civilisation itself [woolwicharsenal.co.uk], implying that the impact of the break-up of The Doors created tear in the fabric of human social history that was not simply limited to the decline of scientific endeavour.

      I'm old enough to remember Comet Bennett, in the early winter of 1970. I walked to school every morning, keeping my eye fixed on it, much to the irritation of the drivers that I somewhat randomly shared the roads with.
          I had a 4.5" Newtonian back home; but telescopes are not the best means of looking at comets. A decent pair of 7x50 binoculars are much better.
          I'm looking forward to this one. I took some good pix of McNaught, just at sunset, just north of the Golden Gate Bridge. This time I might do better.

        I'm just old enough to remember seeing Halley's Comet in '86 and telling my parents I'd be too old to remember the first sighting when it came back in 2061.

        And I remember the next day at school when the teacher asked if everyone saw the comet, and one person proudly announced that he watched it on TV. That was the first time I said the word "dumbass" in public. I have a terrible feeling that the percentage of kids who tell the class they saw the comet on TV (or "YouTwitFace" -- the future conglomerate of YouTube, Twitter and Facebook) will be much higher the next time around.

    • So, what's the deal? Someone want to explain? My understanding of Kohoutek is limited to old "Snoopy" cartoons.
      • Kohoutek was hyped to be very spectacular . . . folks were even wishfully speculating that it might have been the Three Wise Men Jesus Birthday Star.

        But it fizzled out. The Snoopy comics were probably more interesting.

      • Kohoutek was supposed to be a brilliant comet once it emerged from behind the sun on the outward leg of the orbit. What came out was what in pyrotechnic terms was a damp squib.

        One theory I heard posted about was that the comet's trajectory came too close to the sun and the heat actually burned the surface and fused it into a organic mess, like tar, and it was unable to vent as it should have. Another was that it broke up behind the sun.

      "Because the orbits of the two comets are similar doesn’t necessarily mean that the 1680 comet is the same as C/2012 S1 (ISON). It’s more likely a fragment of that comet. The orbital period of the 1680 comet is somewhere around 9,000-10,000 years, so the last time it was near Earth was long before the birth of Christ."

      10 AD is outside the range of dates in which the birth of Jesus could have happened. At that time, Herod was already dead for over a decade.

      If you are interested in a good overview on the theories about the star of Bethlehem, I've found this page [astronomynotes.com] quite informative.

      • It's much easier to believe that the mythology was cribbed from other sources or made up out of whole cloth.

        That goes for the rest of the miraculous happenings too. It's almost as if someone wanted to hijack the moral teachings and substitute idol-worship. Even today the latter seems far more popular than the former.

      I saw Comet Hale Bopp quite clearly from beside a pool in a Las Vegas hotel, surely one of the most light polluted places in the world. I saw it much more clearly from my home in the English countryside, but a good comet can get through a lot of pollution.

      I can spot the full moon quite fine. Indeed, even when the moon is almost gone, I can see it quite well. And I'm living in a place with no lack of light pollution. I guess you know the sky only as seen from inside a big city, where there's not only lots of light pollution, but also enough of regular pollution which both dims the light from the sky and increases the effect of the light pollution by scattering back much more light than relatively clean air would.

      The descriptions so far are a bit vague to give precise directions. Because comets are shedding appreciable mass, which can have a rocket effect on the trajectory, and they're typically tumbling irregularly, and they're warming up (irregularly, under the influence of both previous effects) then this early in an apparition, it's not really worthwhile making close predictions of the comet's path through the solar system, and thus of it's track across the night sky.
