I really really hope so. Except I think the estimated number is 640. So let's hope it went to hell 639 years ago. =D
Sure, it won't be a second sun, but it'll be a pretty bright dot in the sky.
Alright so let's assume that Beatleajfdlsa is exactly 640 lighyears away, and it blew up exactly 640 years ago minus one day.
So if someone happened to be looking at Beatlasdfoasdfj tomorrow night, they would theoretically be able to see the explosion in action, right?
I mean obviously since the distances are so far it wouldn't be a very dramatic explosion, but it's still something.
That'd be pretty baller.

Woah. What do you think a few weeks of no darkness will do to the environment? That's got to screw with your circadian rhythm...
I wonder if any animals or plants would get screwed up by that? Like nocturnal hunters/scavengers might be in trouble, o.o;
LOL! You might wanna check up on midnight sun on wikipedia.

Um, thanks?
I'm sure the creatures living in parts of the world which never experience this phenomenon are used to it.

its daylight nonstop there because the sun never sets it rotates or earth does i dont care to know which one turns it wont make me a smarter person, but i know one spins, and since its so up north it does not set too ften. only a couple months of night time or something? then a bunch of day? i donno, anywho! i hope technology fails and all of earths money is lost, because money is a disease just like drug addiction. only difference is government gives us this drug(money) and weeee elooooooove it. :D haha were so screwed either way. yes this has barely anything to do with the topic, but i let my mind roam where it wants while typing on internet.

Neat.
I'm sure there will be thousands of doomsayers (just look at the LHC rabblerousing, the birds and fish dying, or even the oil spill). I'm also positive there will be riots and crazy people everywhere. Animals will probably be negatively affected, first one that comes to mind is bees who use the sun to navigate.
But goddamn would that be sick to watch.

Super deja vu right there haha...
I doubt the light intensity from a supernova will be anything near "a second sun." Most likely, it'll just look like a glowing blob in the night sky.

It won't look like a supernova in a movie. A supernova lasts a very long time.
The most recent supernova that was visible in the milky way in the 1600's was visible during the day for three weeks, and visible at night with the naked eye at night for 18 months. When it explodes you'll have to try pretty hard to not notice it.

Neat to imagine, but the chances of it happening in our lifetime I would say are very low.
Edit- btw Wishbone your post was very disappointing. I thought you were smarter than that. =]

EDIT: I'm not going to bother responding to any of this 2012 business either. Those of you who think something might actually happen are profoundly deluded. Not to derail the thread too much, but if too many people honestly believe something will happen then they may cause something to happen. Thankfully I believe that most people aren't that retarded. Edit: obviously people here can't cause a supernova there... should go without saying that when I say "cause something" I mean something a little more down to earth.
if this was the case we would have seen god by now....

Technically, since betelgeuse is estimated to be (650?) light years away, this would all be past tense. It would have had to already go supernova in 1362 for us to see it in 2012. I like this way of thinking. It's intriguing to think that we are looking into the past whenever we look into space. When you think about it, everything you see and hear occured in the past. When you look at someone, you see them the way they were a teensy amount of time ago, not the way they are right now. Time becomes such a cool concept when you start to learn more about physics and relativity. It becomes so hard to pin down a true "now", because your "now" is different from mine.
Even more interesting once you get into the metaphysics of what time is. Unless your a presentist ofc, but that has its own problems outside of identifying the present

Well, Empyrean is just saying that all this is total bullshit; some kind of science-tabloid crap.
So can we just close the thread then? If its entirely not true I don't really want to read about it.

Good thing I just bought new Versace sunglasses.

The title seems fairly misleading but the topic of the possibility of witnessing a supernova in the night (and possibly day) sky is still interesting. This thread has also cleared up a lot of misconceptions about the issue. You are of course free to not continue reading the thread.

Betelgeuse Betelgeuse Betelgeuse!

Misleading title
I'd like to witness a supernova.

Reading this thread makes me want to go watch Sunshine for the 615616384th time ^^

"Soon"
But this is a term relative to space time. Ergo- within the next million years or so. Incredibly good chance we won't live to see it, but I sure hope we do!
Also, there are a few recordings of this happening in recent history(the past 1500 years)
Google it up,sonnn
