| | | Orion Explosion?
I was reading in the local news that the red star (on Orion's shoulder) is imminently going to explode. However, all it says is that when it happens it will be spectacular. What is didn't say was whether you would be able to see it through binoculars or not? They also didn't say what to expect visually? We've got some cold, clear nights ahead and can see Orion well from here, so was just wondering?! |

Hiya tufftie,
I'm not really up to speed on these things but these stars, aren't they seen by us well after things have happened due to the speed of light?
Will the predicted time/date take into consideration the time lag?
Despite the great views of the constellation at this time, we wouldn't want you catching cold down in the dell waiting for the big event.  |

It is very cold here was really hoping the explosion might warm it up a bit !!
The long and short answer to your questions is...no idea - my foundation year at Uni covered basic astronomy but it was a while ago now... |

'Imminent' in astrological terms is within the next 10 million years, so I wouldn't hold your breath waiting!
The reddish star on Orion's L.H. shoulder is Betelgeuse. Here's a site showing the relative sizes of the planets and stars: Relative Sun sizes

Apparently when it goes bang I think I heard it would fill the sky like a second sun. Dunno how true this is. |

More like in 3 Million tears time.Star is 600 light years away.Would have exploded Centuries ago may be as a supernovae, bright as a second sun for 3 months then fade away.It may be possible to see some light from Earth if we are still around when it happens.

That's a shame - the news article made it sound like it was going to happen any day now! Would be good to see it - potentially spectacular. thanks |

As far as I know it could expode tomorrow or in 10 million years we might get lucky. In 1054 there was a supernova visable from earth, I think it was the Crab Nebula. However Betelgeuse is much closer and could be spectacular if it goes supernova in our lifetime. |

fingers crossed eh?! I was reading it will be a class 2 supernova (assuming it hasn't already taken place) which means the star would have to be at least 9 times the mass of the sun! |

Luckily most such news items are totally overhyped and screwed in translation from scientific papers - clearly it has the desired effect
