Two of the brightest and most distant supernovae ever recorded have been discovered. They are about 10 billion light-years away. The discovery recorded by Astronomers affiliated with the Supernova Legacy Survey (SNLS) is estimated to be 100 times more luminous than a typical supernova, leaving scientists speculating how they can emit so much light. Lead author D. Andrew Howell, a staff scientist at Las Cumbres Observatory Global Telescope Network (LCOGT) said in a press release: "At first, we had no idea what these things were, even whether they were supernovae or whether they were in our galaxy or a distant one." "I showed the observations at a conference, and everyone was baffled. Nobody guessed they were distant supernovae because it would have made the energies mind-bogglingly large. We thought it was impossible." Read more at Design & Trend.
