Rumor of Betelgeuse's Death Greatly Exaggerated 356

The Bad Astronomer writes "A rumor is spreading on the Net like wildfire that the red supergiant star Betelgeuse is about to explode in a supernova. This rumor is almost certainly not true. First, it's posted on a doomsday forum. Second, it's three times removed from the source, and is anonymous at each step. Third, the evidence is shaky at best. Plus, even if true, the supernova is too far away to hurt us. But other than that ..."

        What's new is that the doomsday tomorrow nuts have something else to latch on to, since 2012 has been thoroughly debunked.

        Of course it is possible that it already has gone supernova, and that the light and hard gamma front will reach us tomorrow morning.

        Fortunately it's far enough away that the only people who are going to notice anything other than a bright light in the sky are gamma ray astronomers, and astronomers who work on supernova theory.

        It'll be a great day for astronomers when it does go, however, a supernova that close and that thoroughly studied will give us a lot of hard information on supernova. For example, IIRC Betelgeuse was the one of the first stars to actually have it's angular diameter measured (1921) and surface imaged using interferometry.

        I'm old enough to remember when they imaged it's surface, at the time it was an incredible achievement.

        If Betelgeuse does go supernova, it will definitely be a naked eye object. For example, the Crab supernova was recorded by Chinese astronomers who noted a bright object in the sky during the day.
        •   Like I said, for most everyone it'll be a bright light in the sky... actually, given it's proximity and size, it'll probably be easily visible in daylight. That would be awesome, supernova that bright are extremely rare :-)

      Because if anyone (or anything) is around to notice itself existing, it is safe to say conditions appear to allow their existence. Ergo, only those who who live in those conditions will be around questioning why would everything work out so nice for life when the universe appears quite hostile towards existence.

    The blog writer complains that this rumor is "spreading like wildfire" but only cites to a single forum where the rumor apparently started. The blow writer then makes a snide comment about a "doomsday" forum, and then spends time with what appears to be an exasperated manner of speaking declaring that a supernova at that distance wouldn't cause any danger, only the original forum post never said it would--it basically saying how cool this would be to see. Why does it feel like a manufactured controversy? As best I can tell this anonymous forum poster may have been mistaken, but the reaction from the Discover blog is ridiculously out of proportion to that mistake.

      Probably because of statements like these:

      When it collapses, it will be at least as bright as the full moon, and maybe as bright as the sun. For six weeks. So the really lucky folks (for whom Betelgeuse is only visible at night) will get 24 hour days, everybody else will get at least some time with two suns in the sky. The extra hour of light from daylight savings time won't burn the crops, but this might.

      If this is really as bright as the sun (and no one is really sure; this is about the biggest star that's ever been recorded)...then all the other doom scenarios become small beer.....

      Hmm all this talk of 6 weeks of constant daylight and two suns in the sky from Betelgeuse which happens to be not far away at all from where google sky, wiki etc blacked out an area said to contain nibiru

      photons are photons and as bright as the sun would include as hot as the sun.

      Maybe it won't be as bad for people who are in the winter hemisphere. Or not. Geez. No part of the planet would be unaffected.

      Those were from page 1 of the forum thread. Not exactly a bastion of critical thinking.

        It's an astronomical mistake on a forum I've never heard of, unconnected to any sort of conspiracy or doomsday theory. Why does it even need to be publicly debunked to this extent? It kind of reminds me of that time James Randi went all ballistic over some obscure brands of speaker cables.
        • I see your point, but regardless of the source or relevance, it's never a bad practice to debunk faulty logic or unsubstantiated claims when you see them. It's good for people to view claims with a certain level of cynicism and requiring evidence.

    Can't remember the author, but it goes like this:

    Amateur astronomers are out watching the sky for the rumored light from a star that had gone supernova thousands of years before. The supernova was predicted by astronomers as early as the middle ages. It was supposedly going to be very bright. Well, the sun rises early...or at least some brightly shining object. But one of the people corrects the questioner, stating that it is the hour of the moon's rising and it must be reflecting the light from the new star. Someone suggests that it seemed to be getting rather warm.

    Short of it is, this exploding star's light was several times more intense than even our Sun. In the short term it created massive weather effects -- tornados, typhoons, etc. But the air temperature in the first day of its arrival soared to over 200 degrees F - the oceans began to boil, it was unbearable to be outside. The people who survived until the first night -- when the air temperature dropped to somewhere over 130 F -- began pondering what life forms would carry on after this, because it wouldn't be humans.

    There was a similar something in the news last year -- light from an ancient supernova finally reaching Earth and it made me think of this story then too. Not sure what happened to that one.

    The rumour was it will occur in the next few weeks, similar to SN 1054 http://en.wikipedia.org/wiki/SN_1054 [wikipedia.org]

    [quote]SN 1054 (Crab Supernova) was a supernova that was widely seen on Earth in the year 1054. It was recorded by Chinese, Japanese, Native Americans, and Persian/Arab astronomers as being bright enough to see in daylight for 23 days and was visible in the night sky for 653 days.[1][2][3] The progenitor star was located in the Milky Way galaxy at a distance of 6,300 light years and exploded as a core-collapse supernova.[/quote]

  • We've know for ages that Betelgeuse was about to go supernova. Of course, that astronomy talk meaning "probably within a few centuries or so". I didn't even see anything in the article that implied that this was unexpected. It's true that the author personally projected all sorts of disasters, but he didn't even claim to be an astronomer.

    So this is a "Yawn" story, not even worth a disclaimer.
