back to article I've seen things you people wouldn't believe. Winking red supergiants sneezing hot gas 650 light years away

The light from the red supergiant Betelgeuse dimmed to a record low earlier this year, leading stargazers to speculate it was about to explode as a supernova. But now it appears the aging sun merely had a stellar sneeze. Last autumn, Betelgeuse started going dark, losing two thirds of its brightness by February. Yet by May, …

    Just brilliant

    > Dupree compared the behavior to a “sneeze”

    Just brilliant. Now even stars are sneezing in our direction without wearing a facemask.

      Re: Just brilliant

      No no no, Betelgeuse is a polite star, the dimming is because of wearing a mask!

    Scientifically speaking

    It appears that Betelgeuse had too much beer and curry, which may have caused a severe outgassing event.

    An "outgassing event" is not a sneeze

    It has another name I guess the scientists were too polite to say.

      Stellar Parp‽

      Stellar Fart‽

      Stellar Shart‽

        From the pictures the star clearly lit it so it would be scientifically classified as a Stellar Flaming Fart.

        For Dupree's information, US science shows typically refer to it as a burp. But that may be too risque for Haavaard.

        I'm still hoping for a supernova in my lifetime. Make it happen boffins.

          You don't have to wait all that long.. there's one..

          There's another, pause, and another.......

          On average, a supernova will occur about once every 50 years in a galaxy the size of the Milky Way. Put another way, a star explodes every second or so somewhere in the universe.

          Naked eye visible supernova is what I suspect you meant. Be careful of what you wish for.

      The outgassing is probably due to an upcoming election, all the politicians are talking at the same time.

      birthing pains for a baby planet?

      first thought: that gas and dust may someday coalesce into a stable orbit...

      also thought: Planet Pffffft

    Stelar Fart ?

    From the Southern End? Where I come from that would be refered to as a wet fart.

    "...the supergiant was undergoing a severe outgassing event..."

    I had one of those in college after eating Egg Foo Yung and drinking beer at a seriously dodgy Chinese restaurant. I thought I was going to get thrown out of the car on the way back to our rooming house, and no, I don't mean after the car was stopped. My roommate wouldn't speak to me for about a week.

    Headline for the win

    Kudos to El Reg for the headline, given that Betelgeuse is indeed the shoulder of Orion. Or possibly the armpit of Orion.

    A star does something 650 years ago and you call this news??

    Looks like your home planet may not be around much longer.

    Apologies for the Yahoo title as well.

      Re: Ford! Zaphod! Don't go home.

      Perhaps it's not an outgassing event, nor a sneeze, but a Hrung, collapsing.

    we get the fart jokes - enough allready !

    Seriously, though....

    This is interesting. We reckon that all elements heavier than Iron are the products of supernovae. Assuming that Bg is about to supernova, it is likely that the outgassing is more than just hydrogen/helium. If the content of the materiel could be tested, there might well be an oppertunity to calculate when it will go bang - by estimating the percentage of Iron and other elements in the outgas This might not be possible, but it would be interesting to find out. It spat out a massive amount of material (which will never fuse now that its left the caronasphere). If we know the ratios of material, we might also learn if this is common to pre-supernovae stars as we have an idea of the ratios of stardust elswhere....

    This is possibly a big deal! Well done spotting it.

      Just what I was thinking; but then I'm trying to formulate a joke about dark matter.

    The iron only gets formed in the impreeive heat and pressure of the an explosion.

    The current out flow is a bit of the surface layer which is almost all hydrogen

      The iron only gets formed in the impreeive heat and pressure of the an explosion.

      No, Iron is the end product of fusing progressively heavier elements until the star runs out of fuseable material.

      With no more fuel to burn it goes kaboom and releases the Iron from the core to space.

      Elements heavier than Iron come from a variety of stellar explosions, either collisions or death rattles.

    "Betelgeuse is once again growing fainter before our eyes, and has been fading away since June."

    I wouldn't know - I've not seen the night sky since May. Even on clear days it seems to cloud over at night. I've seen one Perseid - it literally fell out of Perseus's pocket like the old boy was dropping change on the floor. That's it.
