SN 2006gy
SN 2006gy is an exceptionally bright supernova, the explosion of a massive star. It released an enormous amount of energy, making it the brightest supernova observed at the time. This extraordinary brightness suggests the star was extremely large and had a complex life, possibly undergoing multiple eruptions before collapsing. Its intense luminosity challenges existing models of stellar death, providing valuable insights into the lives of the universe's most massive stars and the processes that lead to such powerful cosmic explosions.
