That red star that marks Orion the hunters shoulder may explode in a type II supernova at any time.

Betelgeuse would become an intense white dot as bright as the full moon. It would not be safe to look at and it would turn the night sky blue.

It would not destroy our world but it could influence mutations and change the course of evolution.

You mean any time in the last 600 years -- or next thousand or so.

Beetlejuice is a super red giant star already. It is in the later stages of it life. Because of its size it will probably go nova or better. As to when? I haven't seen any articles saying when. Technically it may have already and the event hasn't reached us yet. It is about 520 million light years away.

It has been rumored for years as the next star likely to pop.

In astronomical terms anytime can mean sometime in the next 100,000 years!

The next star WE KNOW OF likely to pop. The universe is a pretty big place, so even as we speak...

It'd be kewl if it popped soon. I waited decades to see Hailey's Comet, and, well, this time around its performance was less than spectacular. (One of my life's greatest disappointments, in fact.)

Not sure there'd be any danger of retina burn from looking at a Super-nova from Earth. That doesn't sound right... but I can get a welder's glass. :)

Edit: It'd be kewl if it popped 520 million years ago. (We Earthlings can be so parochial.)

this gives a good visual of the size of Betelgeuse.

its so massive it would take 8 quadrillion earths to fill up.

i wonder how many days it took God to create Betelgeuse?

Do the math. If it's 520 million light years away. It'll take 520 million years for the light and gamma radation from it to reach us. It will take 5 billion 200 million years for any debris to reach us. Unless of course it implodes instead. Then it'll become a black hole.

Exactly what I was thinking. Soon is a relative term in astronomy. Could mean it happened already or not for millenia after our time.

It may be massive in terms of size, but not density. A red giant star is only a stage in the star's life cycle and is not the star's original size. Our own sun will one day become a red giant engulfing the earth.

Red stars can not super nova in the same way a blue star does since they do not have enough mass. They will shead their outter surface, but they can not implode like a blue giant star does.

The most massive stars are blue giants, and they are very unstable. They rotate so fast because they are so massive that they are on the verge of flying apart. When the star's core becomes full of iron and runs out of fuel, and since iron can not be fused, it's core collapses under its own gravity and it implodes becoming a super nova very likely leaving behind a stellar black hole in its place.

It is true that it is less dense but it is still much more massive than our own sun will ever be even a red giant.

Also I misspoke earlier, it is about 520 light years away not millions. Yes I know that was a rather large error :)

Still Beetlejuice is likely too far away to have serious effects on earth cause by its demise. It would still be an amazing this to see the results of though.

And Wiz, if it happen 500 years ago I might still get to see it.
