After the supernova in a star’s life cycle, what else is formed in addition to a nebula? red giant or protostar neutron star or red giant protostar or black hole black hole or neutron star

black hole or neutron star

Explanation:

When a very massive star reaches its end, it runs up on its fuel. The nuclear fusion reaction in the core stops and the star goes supernova. Most of the mass and radiation is expelled out in few seconds. The event is brighter than the brightness of the entire galaxy. The remaining core after supernova collapses to form either a neutron star or a black-hole along with a nebula.

enhanced global partnerships and exploration capabilities may advance international preparedness for protecting the earth from catastrophic events such as some asteroid strikes, advancing collaborative research on space weather and protecting spacecraft by developing new means for space debris removal.
