Answer:
supernova are like a phase of life cycle of stars.
Explanation:
when a heavy star (mass beyond Chandrasekhar limit) exhaust it's fuel then the gravity lead and exceeds the pressure developed due to fusion and then it starts compressing until it reaches certain point,we call singularity. now,if the star is really massive it'll burst out due to its own gravitation,which results in a denser singularity and reminent that remains is called nebula.

nebula = remains of star after supernova.
