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.
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.
its not a massive or a dwarf star
A massive collapsed star is a dead star.
When the most massive stars reach the end of their life cycles, they explode in a phenomenon known as a supernova. This dramatic event occurs after the star has exhausted its nuclear fuel, leading to the collapse of its core and subsequent explosion, which can outshine entire galaxies for a brief period. Supernovae play a crucial role in enriching the interstellar medium with heavy elements and can lead to the formation of neutron stars or black holes.
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.
