Good lord, wow. Talk about your birther bat-boy journalism. We`ve known for years, decades, Betelgeuse is entering nova stage and that it could go anytime in the next million years or so.

what i don`t get is that even if it goes supernova tomorrow, isn`t it many light years away? so it "would take as many years for the light of this event to reach us, right? Wikipedia: "~650 light years away" so wouldn`t we not actually SEE anything for at least 650 years? Some smart guy help me out with this."



while it is correct that it takes that long for the light to reach our Earth, look at it from the stars point- if the star were to supernova next year, it would have happened 649 years ago time wise. this is why scientist are looking at the stars farthest from the Earth, cause they show what the universe was back then. for all we know most of the stars in the sky are already burned out but we are receiving their light just now.

"In fact, a neutrino shower could be beneficial to Earth"

"UPDATE: To clarify, the news.com.au article does not say a neutrino shower could be beneficial to Earth"

There are more things wrong with this article other than the fact it`s not really a story.

The last supernova was 140 years ago. The last one in our galaxy was in 1680. Nobody alive today has seen one. Historical text of supernovae have ranged from the "brightest light in the night sky" to "daylight at night". It would be an honor to witness one first hand. One can only hope it happens in their life.

morbay- any information we have about the star has already taken 640 years to get here. this means the star has already exploded and the light we would expect to see is already on its way.

The star is roughly 640 light years away, IF the star explodes in 2012 the light won`t reach the earth until 2652. Sounds like we are safe....for now. ;-)

Given the time frame they set on this I would say the entire article is pretty irrelevant to any of us. They are basically just saying if this star went supernova we could see 2 suns with a huge IF in there.

The headline makes it sound like some apocalypse scenario is going to happen. Betelgeuse is expected to explode in the next million years. To put that in perspective, all of human civilization has been around for a scant ~10,000 years. Yes, it is possible that Betelgeuse might even explode within the next millennium but the possibility if it exploding next year are almost nil.

"Oh lordy me, not this bull again.

It`s far too far away. If it went supernova long enough ago for the light to reach us next year, it would (a) not be anything like a second sun and (b) would not be anywhere near as bright as a second sun.

It`s all bull, and added to it is the bull that if Betelguese went nova next year we`d see it next year.

Besides, there`s no way to get even a vaguely accurate prediction of when it went or will go nova. Might have been 400 years ago. Might not be for another couple of hundred thousand years.

There`s so much bullpoo being tossed around that the huge steaming pile of bullpoo might reach enough mass to become that second star."

Pretty much. The scientists behind this version of the story are on the same page as you are. You can`t predict when it will happen (and by that, they mean when we will observe it happening, which will be approximately 600 years after it happening). So, we might see it nex

"i thought sun was just the name of our star...or am i mistaken?"

You are mistaken. The name of our sun is Sol. It`s called The Sun, with capital letters, as a common name. Like dogs are called dogs, but their scientific name is Canis familiaris.

I think generally when people say it might go nova next year they mean we might see it next year. The fact the light takes thousands of years to get to us is interesting but irrelevant.

In case anyone is wondering, I am including the sun in that. Sol couldn`t go nova unless you pulled stars from somewhere else and rammed them into Sol - if you added at least a dozen times as much mass, the combination might possibly go nova eventually.

As for the sci-fi idea of a weapon that makes a star go nova...it`s a plot device. You can`t possibly add enough energy to do that. Our own star, which is pretty small as stars go, is a nuclear fusion reactor nearly a million miles wide that converts about 5,000 tonnes of matter to energy per second, or about 5,000,000,000 times the energy of the nuclear bomb dropped on Hiroshima. Every second. Firing any weapon at that would be like adding a drop of water to an ocean.

[quote]If the supernova is that close, isn`t that when gamma rays burn the poo out of the Earth?[/quote]

No, that`s a gamma ray burst.

A supernova isn`t dangerous unless it`s within about 25 light years and even then it wouldn`t burn the poo out of the Earth. It would need to be right next door for that. Since the nearest star that could just about possibly go nova is Spica and that`s about 265 light years away, we don`t have to care.

As for gamma ray bursts, they could be dangerous within about 6000 light years but they`re highly directional and rare. Current estimates are that it`s unlikely that one has ever occured that close to Earth, probably won`t for a few billion more years, would almost certainly miss Earth if it did and wouldn`t cause massive devastation if it did hit Earth - it might blind people looking directly at it and it might stop plants photosynthesising for maybe as long as a minute.

So for a period of two weeks sometime in the next couple hundred millenniums, a bright event will happen in the sky....

And this warranted a topic title indicating that we might have a second sun this year...

Yeah, the 2012 part is just the reporter hyping up the story for the crazies who believe in the 2012 doomsday scenario. We can`t predict events of that scale to such a precise degree that we can pinpoint a year. The best we can do is estimating any time now, with a range of a few hundred thousand or a few million years.

"If the supernova is that close, isn`t that when gamma rays burn the poo out of the Earth?"

Nah.. it would have to be much closer.. something like 25 lightyears away before it do any real damage..

"So it could`ve happened already and become visible by next year? "

Yup.. Betegeuse is approx 600 lightyears from earth, so what we see is BG from 600 years ago..

"Really, all I care about in this article is that a supernova could be visible from Earth in the next 1 - 100,000 years. I know it`s a wide margin, but I still think it`s pretty cool... "

Absolutely.. It would be a once in several lifetimes event and indeed very very cool! :-)

With it being close enough to be visible and quite close to going supernova (at least we think so) BG is the best chance we have of ever seing such an event.. I really hope it happens in my lifetime..

It could have already blown up and we wouldn`t know about it because of the distance.."

Really, all I care about in this article is that a supernova could be visible from Earth in the next 1 - 100,000 years. I know it`s a wide margin, but I still think it`s pretty cool... maybe I should be more cynical.

"If Betelgeuse were to blow up, it could be close enough to Earth that we`d experience a mass extinction, yay! Something to look foreward too!"

Betelgeuse being "close" to nova is nothing new. It`s been close for ages and most likely it`ll be close for a long while yet. Still I really want it to nova in my lifetime, it`d be so cool. It wouldn`t be a second Sun like the article says, but it could still be visible in the day and will probably make shadows at night.

Won`t happen in our lifetimes. They`re just trying secondary scaremongering tactics, by naming something with extraordinary power that `could` happen by 2012. When people read this as `apocalypse` and start panicking, then they`ll have another story to write about.

They said it themselves in the article. It could happen tomorrow. So them mentioning 2012 is just to incite fear.

Also it contradicts itself.

1: "In fact, a neutrino shower could be beneficial to Earth."
2: "UPDATE: To clarify, the news.com.au article does not say a neutrino shower could be beneficial to Earth"

Err.. well yes it did.
