They both explode and some parts turn to meteors and some land on Earth.
Though through out the whole thing people think super novas are alien spaceships from another galaxy. Astronomers study these novas and tell us the truth!
They are all astronomical terms for stars or star related.
Depending on the mass of the original star, it is either a black hole or a neutron star.
Nobody knows for sure, but billions of years. It would also depend on when the neutron star, no longer becomes a star. Is it when it stops radiating heat, or x-rays? The star or the remains will continue to be a physical property but will no longer radiate any energy.
It is speculated that a supernova (exploding star), after its reaching its maximum expansion, then collapses into itself, forming an incredibly dark and powerful gravitational force known as a black hole.
A pulsar is a type of neutron star, a collapsed core of an extremely massive star that exploded in a supernova. Whereas white dwarfs have incredibly high densities by earthly standards, neutron stars are even denser, cramming roughly 1.3 solar masses into a city-sized sphere.
They are all astronomical terms for stars or star related.
A supernova is when a massive star explodes. A neutron star is what can be formed after a supernova explosion. See related questions
No. A neutron star is left behind after a supernova. However, some gamma ray bursts may result from a collision between neutron stars.
The supernova remnant will either be a neutron star or a black hole.
Yes, the first neutron star was observed in a supernova remnant. The object, named PSR B1919+21, was discovered in 1967 in the Crab Nebula, the remnant of a supernova that exploded in the year 1054 AD.
A neutron star
neutron star has been observed at the center of a supernova remnant, known as the Crab Nebula. This neutron star, also called a pulsar, spins rapidly, emitting beams of radiation that are observed as pulses by astronomers.
It can either become a neutron star or a black hole. If the star is between 8 and 15 solar masses, it will become an incredibly dense neutron star. If it is more than 15 solar masses, it will collapse and become an even denser black hole.
Neutron Star
A supernova happens when most of the core of the collapsing star has become neutrons, held up against gravity by neutron degeneracy pressure. At this point a shockwave reflects from the neutron star surface, driving the supernova explosion.So the answer to your question is neutrons.
Neutron Star
The factor that determines whether a neutron star or a black hole forms after a supernova explosion is the mass of the collapsing core of the star. If the core's mass is between about 1.4 and 3 times the mass of the sun, a neutron star is formed. If the core's mass exceeds about 3 solar masses, a black hole is likely to form.
