A star in Orion may go supernova and provide extra light. |

I had heard of this as well. But the story I heard was that it would be fatally dangerous to life on earth. But then I can't remember where or on what type of media I had heard about it.  |

Since it is 1,300 light years away or more, it would have had to happen a long time ago for us to see it in our life time!

I read through 4 articles about this and slowly felt my intelligence slipping away. First, we are observing a mass loss, the star has shrunk in on itself about 15% in 20 years and could nova or supernova....next year or in a million or never.This may be a cycle that giant stars go through. Second, since Betelgeuse is 640 light years away the image we see happened 640 years ago. It could have nova'ed since then. We will have to wait for the light to get here from that point in time. Finally, if it did supernova'ed it would appear as a very bright daytime star with the size of a dime held 6 feet away. At night it would be bright as the full moon and cast shadows. Kind of like the 1054 AD Super Nova. As for the neutrinos that will gift us with gold and silver...etc.....neutrinos are massless and pass through everything without interacting. At least we are far enough away that the gamma rays from the supernova wont cook us. Two suns in the sky ??? hardly.....days with no night ???? plu..leezzz.

This reminds me of the article about Mars closest approach to Earth last August and being as big as a full moon to the unaided eye and the brightest 'star' in the night sky, |

I just love it when non-scientific journalists try to report on stuff like this. It was funny that all the reports on this were written by hacks overseas. I found out that I was dead on with all the points I made except I said bright as a full moon but the correct brightness will be like a crescent moon. And the truth will set you free ....... http://www.space.com/10662-betelgeuse-sun.html |

Part of this is to feed on the 2012 paranoia. Many want to believe the Mayan calendar and are looking for answers to explain it. As if they want it to come true. Betelgeuse is too far away to have a Supernova effect the Earth.

No maybe about it; it certainly will. The only question is when. The most accurate answer available is "soon". How soon is "soon"? To an astronomer, 1000 years would be really, really soon, so don't hold your breath waiting for it. |

People send me that email EVERY August. It started with an article that mentioned that with binoculars, mars would appear as large as the full moon to the unaided eye during it's closest approach. But of course, excited folks eventually left that part out, then left out the year (2002 if I remember) and most people haven't ever tried to look at a planet (or the moon) with binoculars or a telescope not on a tripod or motor-guided to follow through the sky at such high power. It's hard to even locate a planet in a telescope without an attached spotting-scope or motorized/computerized guide, let alone binoculars. |

Betelgeuse is too far away to have a Supernova effect the Earth. Is Betelgeuse the name of our current sun? What is a Supernova? That thing about the world ending in 2012 is a bunch a bull. The Aztecs (very smart people a log time ago that are proved by fact to be real) created a calendar that only goes to our time 2012. Some people that like to cause conspiracy think that when that calendar runs out that the world is going to end. It's not going to happen. |

Betelguese is the name of the red star in the constellation Orion. Is is best seen in the SW sky during the winter months. Look for Orions belt-three stars close together. BG is his right shoulder.
Very far away. When it does Supernova- it will give off light, but not enough to create another sun. Could happen in the next 100,000 years-that is still soon.
The sun will not supernova. Its mass is not big enough to do that. It will expand and wipe out the earth.... in 5 to 10 MILLION years.
