सुपरनोवा SN 2023ZCU: ब्रह्मांड की दूरी मापने में नई मदद

सुपरनोवा SN 2023ZCU: ब्रह्मांड की दूरी मापने में नई मदद: Supernovae (SNe) are one of the most violent explosions in the universe. Core-collapse supernovae (CCSNe) are one of these cosmic fireworks occurring when a massive star exhausts its nuclear fuel and can no longer support itself against the gravitational pull. This dramatic death can be so bright that it is visible in a distant galaxy.
