Two Suns? Twin Stars Could Be Visible From Earth By 2012
By Dean Praetorius 01/20/11

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.

When that happens, for at least a few weeks, we'd see a second sun, Carter says. There may also be no night during that timeframe.

The Star Wars-esque scenario could happen by 2012, Carter says... or it could take longer. The explosion could also cause a neutron star or result in the formation of a black hole 1300 light years from Earth, reports news.com.au.

But doomsday sayers should be careful about speculation on this one. If the star does go super-nova, Earth will be showered with harmless particles, according to Carter. "They will flood through the Earth and bizarrely enough, even though the supernova we see visually will light up the night sky, 99 per cent of the energy in the supernova is released in these particles that will come through our bodies and through the Earth with absolutely no harm whatsoever," he told news.com.au.

In fact, a neutrino shower could be beneficial to Earth. According to Carter this "star stuff" makes up the universe. "It literally makes things like gold, silver - all the heavy elements - even things like uranium....a star like Betelgeuse is instantly forming for us all sorts of heavy elements and atoms that our own Earth and our own bodies have from long past supernovi," said Carter.

@failures art,
Unfortunately they can't predict the core collapse very accurately. Betelgeuse has been "ready to go" for as long as we've been observing it, and it could be this way for hundreds of years.

I would love to see it go though. It would be visible in the daylight sky for weeks, possibly months and would dominate the night sky for years.

@rosborne979,
could it become a focused gamma burst and shoot our way, thus cleaning all life off our planet by stripping the atmosphere qand water.
WOW 2012, coincidence? Many think not!

Thirteen hundred light years away? Whatever "will" happen has in fact already happened. We're just waiting for the news wire services to catch up with the news.

If it turns into a GRB and points our way I think it'll just irradiate the planet and kill every living thing. The water and atmosphere will probably fine (thank god).

Funny talking about something that might happen when it already has or hasn'nt happened. If Betelgeuse is 430 light years away, then if it went supernova, that happened 430 years ago, and the light will reach us next year. But that said, it would be quite an event to watch, though I would miss the star, one of my favorites.

A 20 second gamma burst of a star less than 100 light years would strip away 3/4 of our atmospheric Ozone.

I just want to make everybody happy .

So in this case, we needn't worry.

@farmerman,
so it already happened in 1581 ?
here is what wiki reports from that year :

@hamburgboy,
We wouldnt have seen anything on 1581 (or 1571) Because the speed of dark is still finite. Remember on July 4 1776 King George wrote in his diry
"Absolutely nothing happened today"

Actual GRB's are relatively rare and usually very far away. Supernovae by comparison are far more common and localized. I hate to rain on your disaster, but we'll probably get a good light show and nothing more.

@rosborne979,
Unless the gamma gun is pointing at us with a angle of dispersion of about 2 degrees. (Thats a lot so space in space.

Im gonna duck on the other side of the planet during the gamma birst(if , indeed it does go that way).

Try not to worry though. Chances are that if it comes, youll be sleeping and will never know what hit.

This is just as was predicted by the pattern of wooden deer moki that were found in the Andean Alto plana by Hiram Bingham . Theyve never ever displayed these moki because they were supposed to be arranged in a pattern that predicted the end of the world in 2012. This was a bit after the Maya of course but the aliens were giving everyone the information on the Ika stones.


Sorry, Ive been hanging around one of gungas threads and its rubbing off I think.
