Birth and Death of a Star | How Stars are Born and Die | Stellar Evolution | BYJU'S

Scientists and philosophers may debate about whether stars are living or nonliving, but, in any case, stars have life cycles! Stars are born, and stars die!
In this episode of BYJU’s celestial wonders, we explore the life cycle of a high-mass star. Interestingly, what different stages a star goes through, depends on different factors. The life journey of one star may be very different from the life journey of another star.
A high-mass star like Betelgeuse, for example, has a very dramatic star life.
Stars are born in giant clouds of dust and gases, like hydrogen and helium, called a nebula.
At some point, they have enough mass and gravity that the atoms are brought closer together.
When they are really close, a process called nuclear fusion begins. Here, more energy is generated. This energy makes the star shine!
But this energy acts opposite to gravity. Inward gravity and outward nuclear energy keep the star stable for some time.
When matter is used up, gravity overpowers and makes the star collapse.
Betelgeuse collapses with an explosion becoming a supernova!
The supernova changes either into a black hole or a neutron star depending on its mass again!
The life cycle of a star depends on its mass. While massive stars gradually end as blackholes or neutron stars, some average stars end as white dwarfs.

Our sun will not become black hole because it's mass is not that much high. Sun mass is medium

[@aadarshsb4051]

Our sun won't become a black hole instead it will become a white dwarf, this is due to chandrashekhar limit

[@vikranthdevapatal8263]

Our sun does not become black hole

[@Lightson_you]

No , because our sun's core isn't massive enough to become a black hole this limit is called Chandrasekhar limit

[@ashwinikumar4949]

Our sun will not become black hole because it's mass is not that much high

[@prakashbhushansingh9081]

Our sun will not become black hole

[@jmoney2657]

"Betelgeuse" is actually pronounced "betel-geyss"

[@yerpedutanuja7641]

The mass of sun is not enough to become a blackhole🌀🌠

[@dikshantchoudhary4317]

No after its supernova
Sun will turn into a White Dwarf star

[@MayaDevi-pk9bu]

It will perform a Helium flash and become a white dwarf.

[@sanshithashanbhog6612]

Billion years later sun can engulf inner planets in solar system

[@rainashihab1728]

No, our sun will not be black hole because sun don't have that much mass to be a black hole.

[@WowFigures]

Yes. It will.

[@arpitachildren4871]

No

[@staciewilkins2261]

The sun won't be a black hole because it will just be a planetary nebula or a supernova and after the supernova it will end up being a white drawf or a red drawf and it will be the sun again!

[@arungs74]

Sun is a Dwarf star, so it can't be a Blackhole..instead it will become a White dwarf

[@user-rz8kc8jl7b]

Our sun will not become a black hole

[@ridhamgaming7524]

Sun isn't capable
