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


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.


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

If the core of a supernova explosion contains three or more solar masses of matter, it will most likely become a black hole. The gravitational force is so strong that the core collapses into a singularity, forming a black hole.


Will Betelgeuse become a neutron star?

After a supernova explosion in Betelgeuse it will definitely become at least a neutron star. However, because of it's mass it's more than likely to become a black hole. If it does, then it will be the closest black hole to Earth.


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.


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.


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


Will betelgeuse become a black hole?

Its quite possible that when Betelgeuse goes supernova (within a short "astronomical" time scale) that the remaining core will have enough mass to become a black hole. When it does, it will become the most studied "star" in our lifetime.


What 2 things can happen to a star after a supernova?

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.


Sometimes the leftovers of a supernova collapse to from a?

A black hole or a neutron star.


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.
