SN 2006gy was an extremely energetic supernova, also referred to as a hypernova,[4] that was discovered on September 18, 2006. It was first observed by Robert Quimby and P. Mondol,[2][5] and then studied by several teams of astronomers using facilities that included the Chandra, Lick, and Keck Observatories.[6][7] In May 2007, NASA and several of the astronomers announced the first detailed analyses of the supernova, describing it as the "brightest stellar explosion ever recorded".[8] In October 2007, Quimby announced that SN 2005ap had broken SN 2006gy's record as the brightest-ever recorded supernova, and several subsequent discoveries are brighter still.[9][10] Time magazine listed the discovery of SN 2006gy as third in its Top 10 Scientific Discoveries for 2007.[11]
