Two suns to shine on Earth? Maybe
Earth could be getting a second sun, at least temporarily. The Huffington Post website says Brad Carter, professor of physics at the University of Southern Queensland in Australia, 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 supernova at any time. When that happens, for at least a few weeks, we would see a second sun, Carter says. There may also be no night during that time. 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. Doomsday sayers can relax — if the star does go supernova, Earth will be showered with harmless particles, says Carter.
