What can a nebula turn into?

A nebula can evolve into various astronomical objects depending on its mass and composition. Low to medium mass nebulae can eventually form stars and planetary systems, while more massive nebulae can lead to the formation of massive stars. Following their life cycles, these stars may end as supernovae, leaving behind neutron stars or black holes, or they may become white dwarfs. In addition, remnants of supernovae can trigger the formation of new nebulae, continuing the cosmic cycle.
