Earth As A Binary Planet?

In the Star Wars saga, George Lucas imagined a world where twin suns rose and fell in the horizon. Looks like his vision may not be so far-fetched.

 

Astrophysicists say that Betelgeuse, the red super-giant that is the ninth brightest star in the sky, is losing mass—an indication of gravitational collapse. Brad Carter, a senior lecturer of physics at the University of Southern Queensland, explained to news.com.au that the star is essentially running out of the fuel at its core. “This fuel keeps Betelgeuse shining and supported. When this fuel runs out the star will literally collapse in upon itself and it will do so very quickly,” he said. The subsequent explosion will appear tens of millions of times brighter than the sun, meaning 24-hours of light on Earth.

 

“It goes bang, it explodes, it lights up," Carter said. "We'll have incredible brightness for a brief period of time for a couple of weeks and then over the coming months it begins to fade and then eventually it will be very hard to see at all.”

 

The period of time where we have no night will be a pain, but if this actually works(I'm already reading a few articles from credible-yet-forum'd sites saying it won't), suffice to say it'll be very awesome as far as I'm concerned. Seriously, two suns, that's just cool if it works. Can you imagine what the explosion will look like, even from way out here on earth?

Any projected collapse time frame they can predict yet?

My thoughts exactly. =P

 

As soon as I have one, I'll post it here - A star exploding is a once in a lifetime thing, I'm happy to stay up all night to see it.

 

I'm more worried about the "it'll become hard to see" thing.

 

Confused face. Elaborate?

It sounds like the sudden prolonged increase in brightness is going to mess up humanity's eyesight.

Eh, we'll adjust as it gradually goes back to normal. Day and night sunglasses for a few months is worth it for a binary planet.

Earth wouldn't be a binary planet; we'd be a binary planet if the moon was bigger, and the two revolved around each other. We would have two 'suns' for a little bit. :P

 

Which would be insanely awesome -- especially the initial explosion. It'd flash, and suddenly it'd become daytime. You'd need UV glasses to look at it though, but that'd be fine, really.

I read another source that said it won't be that bad... also that we've probably got a few million years. So I guess your ghost will have a pretty cool light show. :)

I think that he means Betelgeuse itself will be very hard to see, since it would have in fact exploded and there wouldn't be a star there anymore. I read an article on this and they stated that such an event would not actually have any bad consiquences besides some extra sunlight. Of course, if you stare directly at it for too long... that would be another story.

 

As for weeks of endless sunlight... hello Alaskan summer. You see, when you get far enough north (above the arctic circle, i believe) the sun doesn't actually set during the summer. (Similarly, it doesn't rise in the winter, which is like a total bummer)

 

:music:

I'll bet that when it happens, you'll have fools running around screaming "APOCALYPSE!"

We'll already have that next year

 

And there will likely be more between next year and when we get the light from Betelgeuse's supernova.

... ahaha wow am I the derpiest or what

 

CARRY ON THEN

Assuming this doesn't take place millions of years from now, I'm guessing this star is opposite of Sol? Because if it weren't then there'd be night-time during the period which neither Sol nor the star's light reaches the blind side of the planet.

 

Either way, I'd be less worried about losing sleep and more worried about the gamma rays, x-rays, and all the particularly nasty rays and radiation that happens when things like this happen. I like my skin; having it cooked or becoming cancerous all over isn't something I'm looking forward to.

I've heard that it's just going to give off harmless (if not beneficial) neutrinos.

I suppose the more dangerous radiation would be near-unnoticable by the time they arrive, what with exponential decay and all.

 

I foresee a boom in production of those weird eye mask things you see people sleeping in in movies.
