Betelgeuse could beon the verge of going nova
- Thread starter Marc
- Start date
While it might outshine the sun momentarily, it will fade rather quickly below that level in an exponential curve. Most reports I've read state it will probably have the luminance of the moon for few weeks, so I wouldn't worry. Either it won't be bright enough, or it will fade below the critical level quickly.
Well, if Betelgeuse goes the way of SN 1054, I think we should start placing bets on what the resulting nebula will look like and what it should be named. 
Dibbs on the Iguana Nebula.

How long does that kind of stuff take, anyway? What would the nova look like after a few weeks? A year? 100 years? How long do novas take to turn into recognizable nebulas?

And of course, the always required Orion 2: Electric Boogaloo.

"How long does it take, ADMIRAL?!"
I guess it would take several decades if not centuries before the literal dust settles, if the observations of the recent and famous SN 1987A are anything to go by. (From what we can see, barely 20 years after its observed Boomsday, SN 1987A's remnant is still expanding through the cosmos)
I remember the early hours of the day in July 1999 the world had been predicted to end, because there were very unusual weather conditions that night where we lived back then. Sheet (silent) Lightning.
I don't think we get that a lot in the UK, that was only the first of two times I've ever seen it for myself. Mores the pity.
I love a bit of Thunder and Lightning, so it was very odd to have no Thunder, but truly breathtaking seeing these dozens if not hundreds of flashes. I couldn't get enough of all that.
My sister on the other hand... well she dislikes storms at the best of times. She was rather scared.... to put it mildly.
Hell of a day for it to happen though. Bizarrest of coincidences it happened on that day!
Incidentally I've dreamt of a star going nova, and watching it from my living room. But I don't live in that house no more!

Orion Nebula?
Oh, that's what they meant when they said "December 21, 2012, humanity will be enlightened".

Orion Nebula?
Mutara Nebula????
No effect really. The light show will still be there, it will just only be visible to the side of the Earth facing it.

And what if that side is the side opposite the sun? Will the whole planet be surrounded by daylight at the same time? Or will night just be a little less dark?
How far is this Orion nebula away. Becuase depending on the location, it actaully might have already happened, remember in order for us to see it, the light had to have traveled many thousands of years for us to see. So we are not seeing day to day or even year to year activity. There is no way we can accurately say that it is going to hit us or that it hasn't already happened.
Speed of light being the absolute top velocity meaning anything to you?
We are seeing day to day activity. We see everything in "real-time" (not live, but in real time). There's no slow motion, no fast forward. Yes, it might have already happened, but that doesn't matter.
