"Discovery: Ancient Supernova's Remnants Revealed in Stunning Composite Image"
Scientists have identified the remains of a supernova that appeared in 1181, known as SN 1181, as the nebula Pa 30 in the constellation Cassiopeia. This discovery was made through the analysis of its chemical composition, suggesting it resulted from a sub-luminous Type Iax event, a special type of supernova. The nebula's central star, one of the hottest in the Milky Way, and its unique properties make it an exceptional opportunity for studying rare explosions. This finding sheds light on a historical astronomical event and provides valuable insights into the nature of supernovae.
