Unveiling the nature of a newly discovered supernova could help build the cosmic distance scale: A detailed study of the evolution of the supernova SN 2023zcu, discovered in 2023 at the edge of the spiral galaxy NGC 2139, located approximately 90.7 million light-years away from Earth, can help estimate the distance of the local universe. Supernovae (SNe) are one of the most violent explosions in the universe. Core-collapse supernovae
