Supernova about to give Earth a second sun.

Can we appoint you as our night watchman for all of us at ATS?And let us know when it starts happening??.

No need----sign up for SNEWS alerts and you will get probably a few hours' advanced notice of it! It's a really cool program, looking for the advance neutrino waves that come faster than the photon wave because the light gets slowed down while the neutrinos do not! We got advanced warning of SN1987A, about 3 hours, and got to watch it "real time" (as in while it happened, and not from video afterwards).

I'm getting really tired of the patronizing tone of your replies.

1. It was you who mentioned BRIGHTNESS, when i stated BG was 9th largest star, as if correcting me.!! lol.
2. I notice you are no longer arguing the point of BG being the 9th/10th LARGEST star.
3.You speak as though the critical mass for Hypernova is known..it is not.!!

As you were wrong on points 1 and 2 and have not corrected your errors, it would seem your knowledge and expertise is clearly dubious.

If you want a debate about it write a thread stating exactly what the mass threshold is.

1)No, you stated it was the "9th biggest star in our galaxy" which is wrong.
2)"Large" and "Massive" are, again, two different things. BG is indeed one of the BIGGEST stars we can see, but indeed not anywhere NEAR the most MASSIVE, which are the hypergiants. I have never contradicted myself on this.
3)You speak as if the mass of a hypernova is a big guess, which it's not! There's a bare minimum required for the calculations to work out, and BG does not anywhere near qualify for these calculations.

If you want to debate about it, just get a few facts straight first, that's all I'm asking.

Let's keep it friendly, guys.

Please address the topic and not each other.

Thanks.

You're right. Let me extend an olive branch and expound upon this size/mass issue:

One of the really interesting and cool things about BG is that it is SOOOO huge, but is really only about 18-19 times the *mass* of our sun. It's rather "airy" as they go, and even has some very weird and partially-explained gas plumes and dust shells around it, which may help us understand the nature of red giants altogether. We *believe* the poles are positioned at a safe axis for Earth, because of a "hot spot" that has been observed and is theorized to be caused by its axial rotation. True, though----this is just a good educated guess based on observations of other stars. Furthermore, we have been surprised by the size of other supernova explosions that don't seem to fit with our current calculations (I linked about one a page or two back). We could always be surprised by old Betelgeuse.

ETA: oh, and something really cool----one of those outer shells beyond the photosphere actually contains water molecules!

There is a theory out there that this star, Beetlejuice, is the Wormwood star. Wormwood is associated with constellation Orion.

Thankyou so much for those links. The one from MIT seems to confirm that neutrinos do mutate which makes the 2012 movie seem more plausible and the Stanford link you posted only backs that up. I'll go look at the IAS link but I suspect that it's going to agree with the other two

So right at the time we're supposed to start seeing two suns by way of Niburu, low and behold, how convienient,
we have betelgeuse. Wad-up? The only thing we need fear is fear itself !

That one (the IAS one) is really out of date, but gives the whole history for the concept behind the SuperK project, which has within the last year made its first groundbreaking discovery on mutating neutrinos (read the latest news item on that page, it's the homepage for the project)

I was really excited about this but buried in the article it says this could happen a million years from now. I wonder what it would do for the earth to not have night for a while. Would species of fungi and the like die off?

Oh yeah sweet because the new son gets to replace the old dying one. Maybe winter would disappear.

I don't understand how they can say it could happen within weeks or a few millions years... can they not measure the distance from the star to earth to know when the light will arrive? Or is it that they don't know how long the star will take to use up all its hydrogen?

It's already gone super nova. They are trying to calculate the time the light from the star will reach us. Its 600 light years away.
