After a supernova of a very massive star, the core collapses to form either a neutron star or a black hole. The outer layers of the star are ejected into space, enriching the surrounding environment with heavy elements. A bright burst of radiation, known as a gamma-ray burst, may also be emitted during this process.

What happens to a massive star when its fusion period is over?
Once a star's nuclear fusion has ended, it will collapse inside its core and become what is known as a white dwarf. Its outer layers will shoot out into the universe as planet nebula. If they are very large, stars will explode into a Supernova and their core will collapse into a black hole.
What is the small dead star?
A small dead star is typically a white dwarf, which is the leftover core of a star that was not massive enough to become a supernova. White dwarfs are very dense, about the size of Earth but with the mass of a star.
A very small dense star It forms after a huge massive star explodes and then collapses A teaspoon of it matter would weigh millions of tons?
The description matches that of a neutron star, which is formed after a supernova explosion of a massive star. Neutron stars are incredibly dense, with matter packed tightly together. Due to their high gravitational pull, a small amount of neutron star material would have an extremely high mass.
The final stage in the evolution of the most massive stars is an?
The final stage in the evolution of the most massive stars is a supernova explosion, where the star collapses and then rebounds in a powerful explosion. This explosion can lead to the formation of either a neutron star or a black hole, depending on the mass of the collapsing core.
Is a red dwarf star made from a supernova?
No, red dwarf stars are not made from supernovae. Red dwarf stars are low mass stars that form from the gravitational collapse of gas and dust in interstellar clouds. Supernovae, on the other hand, occur when massive stars reach the end of their life cycle and explode.
The explosion of a very massive star is called what?
well what you gotta do is go home a smoke weed
What is a dense collapsed core with a very strong gravitional pull that forms when a very massive star become a supernova?
Neutron Star
Is your sun a supernova or a white dwarf?
Our Sun is currently a main sequence star. It is not a supernova, as supernovae are massive explosions that occur at the end of a star's life cycle, and it is not a white dwarf, which is a type of star that has exhausted its nuclear fuel and collapsed to a very dense state.
Why doesn't a supernova occur on earth?
A supernova can't occur on any planet. A supernova occurs when a very large star, at least 8 times more massive than the sun dies.
Is a supernova massive?
A supernova can be massive but some aren't. Every supernova is a dieing star. Supernovae are exploding stars. They represent the very final stages of evolution for some stars. Supernovae, as celestial events, are huge releases of tremendous energy, as the star ceases to exist, with about 1020 times as much energy produced in the supernova explosion as our Sun releases every second.
What happens to a massive star when its fusion period is over?
Once a star's nuclear fusion has ended, it will collapse inside its core and become what is known as a white dwarf. Its outer layers will shoot out into the universe as planet nebula. If they are very large, stars will explode into a Supernova and their core will collapse into a black hole.
What is the difference between a nova a supernova and a neutron star?
A nova is a star which has a close companion star, and draws stellar material off of it's companion, occasionally flaring up very brightly in the process. A supernova is a massive and hot star to begin with, that tends to go through it's life cycle at high speed, and ending it's life in a cataclysmic explosion. Supernova remnants then collapse into a neutron star - a spinning, very hot pile of stellar ash, so dense that a teaspoonful of it would weigh thousands of tons. If the collapsed supernova star was big enough, it's gravity upon collapse is so intense than not even light can escape from it, and it becomes what is called a "Black Hole".
What are exploding stars?
Dangerous. Novas, or supernovas. Tycho Brahe coined the phrase "nova stellarum" when a "new star" appeared in the night sky. We now know that he was observing a supernova, the death throes of a very massive star.
How stars go supernova?
Massive stars. See related question: 2nd Answer: Yes, massive stars, but ones with another star like a red giant orbiting each other. The to-be supernova 'sucks' material from the other star near it until its mass is large enough to make the star collapse and burst.
What is the small dead star?
A small dead star is typically a white dwarf, which is the leftover core of a star that was not massive enough to become a supernova. White dwarfs are very dense, about the size of Earth but with the mass of a star.
What will a star that's 1000 times as massive as the sun ultimately become?
A star that is 1000 times as massive as the Sun will likely end its life in a supernova explosion, leaving either a neutron star or a black hole as a remnant, depending on the mass of the core after the explosion.
When a very large star explodes it is called a?
supernova
