Betelgeuse might go up tonight, or it might not be for 100,000 years.


Nope, we're not getting a second sun...

"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."
