Supernovae refer to the sudden expulsion of mass and energy when a large star can no longer fuse material matter. It results from the core collapsing into itself because it no longer has nuclear fusion to counteract it's own gravity and it's too dense for electron degeneracy to prevent collapse.

Can a star less massive then the sun become a supernova?
No, stars less massive than the Sun do not have enough mass to undergo a supernova explosion. Instead, they may end their lives as a white dwarf or, if they are even less massive, a planetary nebula. Supernovae are events associated with more massive stars.
What does a massive supernova become?
If enough mass is left over after the supernova explosion, i.e. after material is blown off into space, the star will become a black hole. Less massive stars will become neutron stars. A neutron star can convert to a black hole later, if enough matter falls into it.
A massive stars terminate in a brilliant explosion called a?
it is Supernova
Will our sun become a red giant then will it become a supernova then a black hole?
No, our sun is not destined to become a supernova and/or a black hole. It will become a red giant, but it is not massive enough to cross the threshold and become a candidate for a fate like either of those last two.
What is a supernova and what happens?
A supernova is the catastrophic death of a star, characterized by a massive output of energy.
Is a supernova a type of galaxy?
No. A supernova is a massive explosion, usually from a dying supermassive star.
What is a dense collapsed core with a very strong gravitional pull that forms when a very massive star become a supernova?
Neutron Star
Could VY Canis Majoris become a blue supergiant?
Never.VY Canis Majoris - WAS a blue supergiant. It is now a red hypergiant and will "soon" become a massive supernova.
What type of supernova will Betelgeuse be?
Betelgeuse is expected to end its life in a supernova explosion, likely as a Type II supernova due to its massive size and age. This type of supernova occurs when a massive star exhausts its nuclear fuel and collapses under its own gravity.
Where does a supernova fit into a star's lifecycle?
A supernova occurs at the end of a massive star's life cycle.
Will Altair soon become a supernova?
Highly unlikely in our lifetime. Altair is still on the main sequence and probably has a few billion years left on it. Even when it comes to the end of the main sequence, it may not have enough mass to become a supernova.
Will the sun become a supernova in the future?
No, the sun will not become a supernova in the future. It is not massive enough to undergo a supernova explosion. Instead, it will eventually expand into a red giant and then shed its outer layers to become a white dwarf.
