Nearby star may have gone supernova

June 12, 2009 | Comment icon 44 comments

Nearby star Betelgeuse has been noticably shrinking over the past decade indicating that it may by now have gone supernova, at 600 light years distant the explosion would pose no threat but would provide a spectacular fireworks display.
Pinned prominently on Orion's shoulder, the bright red star Betelgeuse hardly seems like a wallflower. But a new study suggests the giant star has been shrinking for more than a decade. Betelgeuse is nearing the end of its life as a red supergiant."

A species wipe out event? You've got to be kidding me, you dont even know how a star behaves, I just can't take you seriously. With the distance from Sol and Betelgeuse, there will be no such thing as a " species wipe out event". Sorry if I'm being rude, but ignorance just works my nerve. I'm not gonna take the time to correct you, you should do that yourself ( I advise you to do it), but I am going to tell you something: If you're going to make an opinion, please base it on actual facts, otherwise everything you say will be bogus and terribly wrong. And that's what's happening here. And pleas... [More]

you understand it could have eploded 599 years 11 months and 30 days ago. oh well that's better. you say it "could have" is there any definite way to find out?

oh well that's better. you say it "could have" is there any definite way to find out? Nope. We have to wait and see. Fortunately, as I understand it, the explosion would be so massive it would be visible for a few weeks - so there isn't much chance of missing it.

It's against the law for them to disclose that information. They tried to do that with the return of Jesus Christ and they were way off. Anyway, this Jesus told us to just watch. Because only the Father knows. Besides, something that far away could explode and we'll never know it because it could be the other side exploded. What other side exploded? Please elaborate your theory.

The coma is caused by heating from the sun. Thus if it is bigger this time then it is getting more heat from the sun. That's great! Another global warming thing!

I don't know that you can call that any more than just a personal hypothesis available for all to trample, but I can try to climb out of the hole I'm in. Unless, there's more yo... [More]

That's great! Another global warming thing! it could just be closer this time

That's great! Another global warming thing! Nothing to do with global warming. The orbit of a Comet usually takes them to the cold and dark outermost reaches of the solar system to close passesof the Sun. When comets venture into the more intense sunlight of the inner solar system, the ices on the comet nucleus begin to melt and fall away. The wake of particles forms the comet's tail, which can be hundreds of miles long and can often be seen from Earth. Some originate from the Edgeworth-Kuiper Belt, beyond Neptune, and some from the Oort cloud, a spherical shell comprised of millions of bodies... [More]
