Explanation:

A black dwarf is not yet observed as it's a theoretical end - stage of a white dwarf. A white dwarf is what a medium - mass star becomes at the end of its life. A nebula is a large cloud of gas or dust in space. A protostar is the earliest stage of a star's life. A supernova occurs when a red supergiant star explodes. A neutron star is the remains of a high - mass star. A black hole exerts such a strong gravitational pull that no light escapes.
