Betelgeuse Blows (see the link in my post) new
      #5823359 - 04/25/13 11:19 PM

Interesting article on Bad Astronomy. Betelgeuse blew out a huge amount of gas materials that extends out to Neptune's orbit. The mass is about 2/3 the mass of the earth. As stated, Betel is spewing out its outer layers as it continues to evolve. Here is the link.

I hope that is a typo or we're in deep trouble now!

The title had me nervous there for a second...while I'd love a Milky Way supernova, I'd hate to see a unsymmetrical "Betelgeuse-less" Orion!

I think I could live with a supernova remnant quite visible to the naked eye in Betelgeuse's old position in Orion. With the Crab some 6300 light years away and Betelgeuse about 700 LY, one imagines that the "new crab" would be quite spectacular for many centuries. Instead of a shoulder Orion would have a very visible corsage!

You raise a valid point!

I had a dream that Betelgeuse produced a Gamma Ray Burst that annhilated every living thing on earth. The good news is that my dream took place in the year 48,540 AD, a time when most humans have relocated to a new star system 6.8 light years away. A K2 spectral classed dwarf system in the constellation of Cygnus.

The ISS passed just above Betelgeuse at 8:51 p.m. EDT on Friday evening. Both exhibited a ruddy glow through the 15x70 binocular I was using to track the space station.

If a supernova 700 light years away produces enough gamma rays to sterilize earth, moving just 6.8 light years away won't do much good.

In the poster's dream, the future version of himself 48,540 years from now also finds that the future version of the girl he had a mad crush on in high school who wouldn't have anything to do with him back then...instead is the one with a mad crush on him. You know what? It's a dream, so that won't do him much good either!

I give the OP huge credit for dreaming about living on a spectral-class dwarf in Cygnus and watching a supernova destroy Earth rather than the more mundane dreams most of us have about being spectral-class idiots who find ourselves lost on the way to some final exam we're totally unprepared for...naked, about to have our GPA go supernova.

Speaking of dreams, if all goes as planned that's the same year I will have saved enough money to buy a 10" AP Mak.

Actually, it might make a difference if that 6.8 light years is out of the line-of-fire. Gamma ray bursts being highly directional after all.

I don't think supernovae produce directional gamma ray bursts, but a broad shower of them, spreading equally in all directions. I read something about this once, but that was a decade ago, so I can't recall any details. There was an article in S&T about this.

Hypernovae are believed to create directional gamma-ray bursts.

Dang it! I was planning my retirement for exactly the year 50553. I could finally afford it by then.

That thing needs to blow soon! I'm hoping that this might be the early signs of the boom!
