HuskyCaucasian Posted January 21, 2011 Share Posted January 21, 2011 Two Suns? Twin Stars Could Be Visible From Earth By 2012 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.

chw42 Posted January 21, 2011 Share Posted January 21, 2011 Wait a minute... Betalgeuse is 640 light years away. Correct me if I'm wrong, but doesn't that mean that the light we observe from the star is light from 640ish years ago? Because I have a hard time believing that light from a super nova can eclipse the speed of...well...light. Quote Link to comment Share on other sites More sharing options...

Swingandalongonetoleft Posted January 21, 2011 Share Posted January 21, 2011 Awesome stuff. Astronomy has been my favorite thing to learn and read about since I can remember. I actually re-read Hawking's A Brief History of Time this past fall. Amazing things happen out there, probably more than the mind can comprehend at this point.

So, if the star is only 640 light years away, why would it form a black hole 1300 light years away? Someone suggested that Stephen Hawking book to me a while ago. Has anyone else read it? Is it that good? I might swing by Borders tonight and pick it up. I need more things to do while waiting on spring training. Quote Link to comment Share on other sites More sharing options...

The distance to this star is actually quite poorly known. Calculating distances in space is a difficult process sometimes. You sorta do it by measuring the angle to the star from 2 different points in Earth's orbit and doing some geometry. But, this star is troublesome because it has an odd shape (possibly due to a very large and persistent sunspot), because it appears to have a very large velocity in an odd direction, and because its size actually appears to be varying with time. The difference between 640 light years and 1300 light years is who's estimate for the distance is being used. Quote Link to comment Share on other sites More sharing options...

Balta1701 Posted January 21, 2011 Share Posted January 21, 2011 Hoping no one here took too much from the SMH article, but just in case they did. The article kicks off by equating Betelgeuse's impending explosion with the "twin suns" on Tatooine, the world where Star Wars' Luke Skywaker lived. In Star Wars: A New Hope, Luke watches the setting binary stars of Tatoo. When Betelgeuse goes supernova, will it really shine as bright as our sun, perhaps giving us that famous double-sun scene from Star Wars? That's a nice thought, but 640 light-years is still quite a distance, and although when it does blow astronomers think we'll be able to see the explosion for some weeks during the day -- still a very impressive and historic event -- that's a far cry from thinking a sun-supernova combo could resemble any binary star system. But the biggest issue to come out of this article is the ominous and completely erroneous mention of... wait for it... 2012. "The infamous red super-giant star in Orion’s nebula -- Betelgeuse -- is predicted to go gangbusters and the impending super-nova may reach Earth before 2012, and when it does, all of our wildest Star Wars dreams will come true," the article says. .... But what's all this fuss about the star exploding by 2012? That's complete garbage. There is absolutely no indication that the star will explode in the next year or so. Even the most advanced telescopes and sophisticated computer models cannot predict an exploding star with that precision! By the article's own admission, the supernova might not happen for a million years -- begging the question as to why a half-baked 2012 Betelgeuse doomsday theory is even being mentioned. Betelgeuse is a fascinating star, but don't be concerned about its planet-killing ability. It's too far away and it might not go "gangbusters" for another million years.
