Scientists have discovered an ultra-bright supernova in a galaxy 10 billion light-years away, about 3.5 billion years after the Big Bang, during what astronomers call cosmic noon. An ordinary supernova is caused by a violent explosion when a massive star dies. Superbright supernovae are 10 to 100 times brighter than ordinary supernovae, and the mechanism of their formation is unclear. Previously discovered superbright supernovae are located in galaxies with small masses, which makes scientists believe that the environment in which small galaxies lack heavy elements is conducive to the production of superbright supernovae. The galaxy where the superbright supernova is located is an ordinary high-mass galaxy, which makes people rethink the formation of superbright supernova. This means that the Milky way may have had the conditions to produce superbright supernovae.
