The supernova stage itself lasts only a few days or weeks. Once the star runs out of fuel, the collapse into a neutron star or black hole (depending on the remaining mass) should be quite sudden - whatever it takes for matter to fall toward the center.

What will happen to earth when Belelgeuse goes supernova?

when betelguese goes supernova nothing will happen directly to us, but the star will become as bright as the moon in the night sky, and a black hole may form at the site


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 are the types of stars a high mass star can become after it goes supernova?

Once a high mass star goes supernova, it doesn't become any other type of star - it becomes a pile of enormously dense stellar ash, or if it was big enough to begin with, it becomes a black hole.


What is a star that explodes in supernova what does its core become?

Depending on the Mass of the core, they either become a Neutron Star or a Black Hole.


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.


Can a supernova escape a black hole?

No.


If the core of a supernova explosion contains three or more solar masses of matter the core will most likely become a what?

If sufficient mass remains after the supernova explosion, it will become a black hole.


Were did a black hole come from?

Black holes came from old big stars that went supernova as it dies. Supernova causes the star to collapse into a black hole


What happens to stars after it reaches super giant?

It will goes super in heat which mostly going to become supernova and it grows hotter by seconds then it becomes a black hole with extreme heat energy.


What is the adverb phrase of a black hole is the remains of a supermassive star after a supernova?

after a supernova


Which kind of stars become black holes?

Only stars that are much more massive than our sun can become a black hole. When the star dies, it explodes (called a supernova) and then gravitational collapse helps it to form a black hole.


What a star may become after a supernova explosion?

Usually a neutron star, or a black hole, depending on the remaining mass.
