Fear Not A Supernova 2012Greenbelt MD (SPX) Dec 19, 2011 Given the incredible amounts of energy in a supernova explosion - as much as the Sun creates during its entire lifetime - another erroneous doomsday theory is that such an explosion could happen in 2012 and harm life on Earth. However, given the vastness of space and the long times between supernovae, astronomers can say with certainty that there is no threatening star close enough to hurt Earth. Astronomers estimate that, on average, about one or two supernovae explode each century in our g ... read more |
