I'll believe it's true when I'm holding a copy in my hand. Not a second sooner.

I want to rip off your superstitions and make passionate sense to you

RE: 2 Suns in the sky
Second sun (or moon ) would be amazing for the first day, fun for the second, and fuckin' annoying for the rest, if it would last for that long Smile but I want to live that, yeah

RE: 2 Suns in the sky
An extra sun would mean twice the brightness and heat? Might be good for solar plants, but I don't want the sweat to boil on my skin in summer time.

Correct me when I'm wrong.
Accept me or go to hell.

No. It was a metaphoric statement enhanced by art.
The star in question is Betelgeuse.

Please look for my earlier reply in this thread for Explanation.

A Beautiful Photo of the Constellation Orion, and other surrounding stars. The Pleiades is also visible Above Orion. Betelgeuse is the Bright yellow/orange star top left in Orion. (His Shoulder). Also known as "Alpha Orionis" and lies about 430 light years away.
ok, I can't seem to attach the photo. let's try this...http://apod.nasa.gov//apod/image/1101/winterhexagon_westlake_big.jpg
Thank you all for bringing back my enthusiasm for astronomyCool

Well there seems to be a problem with attaching the photo I mentioned... I'll try a third method,,, here goes...

RE: 2 Suns in the sky
So I assume they have evidence that the supernova has already occurred?

Like a particle that travels faster than light that has warned us that we'll get to see the ancient explosion soon?

If we saw it tomorrow, then it means it happened 600-1200 years ago in actuality (however far it is away), but for all practical purposes, it is as if it is happening in real time. It's kind of like talking to someone on Mars. They will send you a message, and it will take 2 minutes or so to get to you, but once that initial 2 minutes has passed, as long as they talk continuously, you will hear them continuously. That's the beauty of the size of the universe. Any particles/shockwaves from the supernova that may hit earth could take much longer to get here, possibly millions of years.

EDIT: Sorry, I didn't mean shockwave, there is no air in space lol. I'll just leave it at particles.

No; What they do have is evidence that the star is in the last stages of it's life. Betelgeuse is somewhere between 300 and700 light years away, so for the sake of simplification, lets say its 500. If it exploded 500 years ago, we would see it this year. Anyway, As I've explained before, when speaking of stars life cycles; + or - 100,000 years is like a sneeze. So it could happen today, or it might not be for another 'X' thousand years. But the "EVIDENCE" is that it is showing (And Teaching) us, how a star's life begins to end.
(It's actually shrinking and expanding in some non stable way!)

RE: 2 Suns in the sky
It is always fascinating to look at the stars knowing that they might not exist by now. :O
