Belelgeuse turning into a supernovae

In summary, astronomers still don't know when or how Betelgeuse will explode, but they don't believe it will hit us any time soon.

With so much hype going around as to Betelgeuse turning into a supernovae in 2012, wonder whether it is possible to predict such an occurrence correct to at least a decade...

Short answer: No.
Long answer: Still no. Details at http://blogs.discovermagazine.com/badastronomy/2010/06/01/is-betelgeuse-about-to-blow/"

With a bit of luck, we'll see it blowing a really big, juicy, complex planetary nebula before it goes...

Thanks for the update

The triggering mechanism for core collapse supernova events is still very uncertain. The predictability appears to be on the order of millions of years.

aww way to spoil the hype. I would die to see a crab nebula type explosion in my lifetime.

So, a mere 500 years ago was not enough? Humans ... so demanding.

I want it now! waaaaaaa!

For all we know it already blew up, after all when we look up at the night sky we are looking into the past... And yes Chronos is correct, the time taken for it to actually blow up is very long (for us). Just because it started the first stages of a supernova doesn't mean it's blowing up any time sooner :S

As the rotational axis is not directed to Earth it shouldn't be that bad. But it would be an impressive sight.

At over 600 light years away, it isn't that close. We'll be fine.
 

1. What is Belelgeuse?

Belelgeuse, also known as Alpha Orionis, is a red supergiant star located in the constellation Orion. It is one of the largest and brightest stars in the night sky, and has a diameter about 1000 times that of our Sun.

2. What does it mean for Belelgeuse to turn into a supernova?

A supernova is a powerful and extremely bright explosion that occurs when a massive star reaches the end of its life. In the case of Belelgeuse, it will eventually run out of fuel and collapse in on itself, triggering a supernova event.

3. When will Belelgeuse turn into a supernova?

It is difficult to predict exactly when Belelgeuse will turn into a supernova, as it is a complex process influenced by various factors. However, scientists estimate that it could happen within the next 100,000 years.

4. What will happen when Belelgeuse explodes as a supernova?

When Belelgeuse explodes as a supernova, it will release an enormous amount of energy and emit intense radiation. The star will also produce heavy elements through nuclear fusion, which will be scattered into space and eventually contribute to the formation of new stars and planets.

5. Will Belelgeuse's supernova affect Earth?

Belelgeuse is located about 642 light years away from Earth, which is far enough that the supernova explosion itself will not have a direct impact on our planet. However, the sudden increase in brightness and energy from the explosion may be visible from Earth and could potentially affect our planet's atmosphere.
