Betelgeuse is getting active
Hey, Derek (and anybody else interested int hsi stuff), look at this:
SkyandTelescope.com - News from Sky & Telescope - Betelgeuse: A Hotheaded Superstar
What do you think about this? The part that really gets my attention is the second-to-last paragraph where they say Betelgeuse's diameter has decreased by 15% since 1993.
I kind of hope I get to see it, and I kind of hope I don't, you know?

interesting.. and since it's 640 light years away, what were seeing happened in the year 1396.....member #3143

That's true. A light year is the distance light travels in one year. So if something is 50 light years away, what you see is actually what happened 50 years ago. Our sun is actually about 8 light minutes away...so if it were to go out at noon one day, we wouldn't know until 12:08.

If it goes supernova, it will likely emit polar jets. If the jets hit us, it'll be bad news. Since there is 640 light years of (4/3)*pi*r^3 between us and the Big B, it's a small chance, but not a non-zero chance.
But it will also toss out a hell of a lot of radiation omnidirectionally, and since the Big B is 900 times the size of the sun ... it will be interesting.

Depending on where you read, it'll be as bright a cresent moon. Bright enough to cast a shadow at night. And you'll be able to see it during the day. However bright it ends up being, it should be bright enough to notice.
I personally hope it happens while I'm still kicking.

is it really possible for it to blow in a few years time?
ive always known that shit like this happens on a thousand year timeframe, in which our existence on this planet are a mere blink of the eye.

They happen daily in other galaxies, and about every 50 years or so in the Milky Way galaxy. They say when this one happens (if it already hasnt) that it will be clearly visible during the day. Imagine how bright that would be at night time if it can compete with our Sun during the daytime. Also i was reading up last night and ironically it was also featured on last nights new epsiode of the Universe, that there is a Binary star system WR-104 that is 8k light years away from earth that they think could potentially be a threat for a Gamma Ray burst. The reason it is such a credible threat is that the poles of that particular star are pointed directly at the earth. When a Gamma Ray burst happens the fastest way for that energy to be released is through the solar poles of the star. http://blogs.discovermagazine.com/ba...mma-ray-burst/
Maybe JS can throw some more input on that topic

Anytime between now and the next thousand years. We may live to see Betegeuse put on a show.
Right now, in Houston, anyway, Betelgeuse is up at 05:15, so we would see it during the daytime and early morning. As winter comes on, it will be visible at night.

Whichever outcome happens, it will explode first. Depending on how much mass it retains will decide its fate after the explosion. But it looks like the remnant will be either a neutron star or a black hole, due to it's mass.
In order of increasing mass, the options are: dwarf, neutron star, black hole.
