Hypernova SN 2015L is the Brightest and Most Powerful Ever Seen
Posted by Guy Pirro on 5/23/2017 5:30 PM
Records are made to be broken, as the expression goes, but rarely are records left so thoroughly in the dust. In 2015, stunned astronomers witnessed a cosmic explosion about 200 times more powerful than a typical Supernova event. At its peak intensity, SN 2015L exhibited 570 billion times the luminosity of the Sun. If that statistic does not impress, consider that this luminosity level is approximately 20 times the entire output of the 100 billion stars in our Milky Way galaxy. This record breaking blast is thought to be an example of a Superluminous Supernova (or Hypernova), a recently discovered and supremely rare variety of explosion unleashed by certain stars when they die. Scientists are frankly at a loss to explain what sorts of stellar scenarios might be responsible for these types of extreme events.
