It happens when a star loses hydrogen
No. Only the most massive stars explode.
A supernova reaction occurs in the life cycle of a massive star that has exhausted its nuclear fuel and reaches the end of its life. The core of the star collapses under gravity, causing a powerful explosion that briefly outshines an entire galaxy.
The answer depends on the original mass of the star. If it was not too massive, it will shrink to a dwarf star. If it was sufficiently massive, it will explode as a nova. A really massive star, exploding as a supernova, will leave behind either a neutron star, a pulsar or a black hole.
A supernova occurs at the end of a massive star's life cycle.
The biggest star - VY Canis Majoris IS in a red supergiant phase and will explode as a massive supernova.
Stars that explode are referred to as supernovae. This explosive event occurs when a massive star reaches the end of its life cycle and undergoes a rapid and intense process of collapse and explosion. Supernovae release an incredible amount of energy and can briefly outshine an entire galaxy.
A supernova occurs in a star's lifecycle when it runs out of fuel and its core collapses, causing a massive explosion.
its not a massive or a dwarf star
A massive collapsed star is a dead star.
Black holes are stable entities in the universe and do not explode. They are formed when a massive star collapses under its own gravity. The intense gravitational pull of a black hole prevents it from exploding.
Because a massive star has more pressure on the core, this creates greater temperatures, which increase the amount of nuclear fusion that occurs. This uses more hydrogen and thus the star runs out of fuel much quicker, that a smaller star.
The way a massive star dies is determined by its mass. Stars with more than 8 times the mass of the Sun typically explode in a supernova, leaving behind a neutron star or black hole. Less massive stars, like the Sun, will eventually shed their outer layers to form a planetary nebula, leaving behind a white dwarf.
