Earth could have two suns for a short time

If nearby star Betelgeuse goes supernova we could end up with two suns in the sky.
Dr. Brad Carter of the University of Southern Queensland detailed a scenario in which if Betelgeuse went supernova it would create what would appear to be a second sun in the sky for several weeks, despite it being 1300 light years away.
Earth could be getting a second sun, at least temporarily. Dr. Brad Carter, Senior Lecturer of Physics at the University of Southern Queensland, outlined the scenario to news. com. au. Betelgeuse, one of the night sky's brightest stars, is losing mass, indicating it is collapsing. It could run out of fuel and go super-nova at any time.

Like an Indian Summer day in Winter?

Like an Indian Summer day in Winter? No, the star is to far away to heat the Earth. You'd have a particularly bright star, but that's about it.

up until someone puts some space stations in orbit around a star with no planets. Don't think it will qualify it as a sun in that case, think it will just be "a star with space stations in orbit around it" Zam And those space stations would be a fully functional battle stations.........? Sorry in light of the earlier star wars quips I couldn't help myself

Great! Now i can pull off a Luke and stare off into the twin sunsets! lol Um the crab nebula was created when a star went supanova in 1054ish I think... I read or saw on tv somewhere that the light was so bright that you could read by it. Well I guess you can read by the moons light too. But what distance is the crab nebula and I guess distance affects brightness or are these things so bright it doesnt matter where you are in relation to it

But what distance is the crab nebula and I guess distance affects brightness or are these things so bright it doesnt matter where you are in relation to it The Crab nebula is about 6500 light years away, betelgeuse is about 650 light years away. So my guess is that when betelgeuse goes supernova it will be much brighter. Zam

I hope it happens during our lifetime, that would be an awesome sight.

I saw something on MSN today about China having a second sunset recently. I couldn't click the link, due to being at work and news sites are blocked (yet this site isn't lol). Anybody have more info on this? Does it have to do with a supernova or is it just an illusion?

Haha I have an answer to my own question after reading a catched MSNBC article. Two Suns "Weeks after a story shot across the Web claiming that the imminent explosion of a nearby star would result in the appearance of a second sun in the sky — a story that was later debunked — two suns were caught on camera yesterday in China. The suns — one fuzzy and orange, the other a crisp yellow orb — appeared side-by-side, one slightly higher than the other. What's going on? Life's Little Mysteries, a sister site to Space.com, asked Jim Kaler, the University of Illinois astronomer who squelched the excit... [More]

2 suns, that star is what 640LY from earth. how bright is this thing going to be. I once read from some nasa page if you where to look at our sun from pluto, it would be just like a bright star. "Since Pluto is so far away from the sun, the sun would look much dimmer and smaller that it does from here on Earth. From Pluto, the sun would look like a very bright star and would light up Pluto during the day about as much as the full moon lights up Earth at night. " The distance from pluto to our sun is 0.00045LY(5.914 billion km), this star is what 640Ly(6,050,723,171,512,320 km aprox) i doubt it... [More]
