what happen;s to a star once it gets older?

Answer 1

It does commercials for Geico Insurance.

Answer 2

That depends on the original mass of the star. If a star contains sufficient matter (Chakasandar's Mass), upon loss of the energetic reactions that prevented the gravitational collapse of the star disappear and the star begins to collapse inwards upon itself. It would go through several stages. It could, throught he collase and ever increasing density of the core, ignite the remaining fusion fuels for one last, spectacular display -- the supernova. The fuel is explosively scattered throughout the surrounding space as the new smaller core collapses even further. It becomes a neutron star. Then finally, when the escape velocity of the gravitational field is equal to the speed of light, it has become a black hole. From which, nothing can escape.

Answer 3

It turns into a red giant then a super nova then eventually turns into a white dwarf. After that it expands then gets smaller and so on. Sometimes they turn into neutron stars which is when all the atoms and gases are brought as close together as possible by gravity. When a neutron star explodes it releases all the of the elements found in the periodic table; it also becomes a black hole. That's as much as scientists know about black holes for now.

Answer 4

Depending on it's size, many things can happen.

Smaller stars can simply burn out and become brown dwarf stars. The largest of stars collapse on themselves in what is called a supernova and can even become black holes.

Middle size stars, such as our sun, will swell up in size as they begin fusing heavier elements. All stars are powered by fusing elements into heavier elements such as fusing hydrogen into helium. Once it begins fusing the heavier elements the star swells in size. Our sun will become a red giant and swell to a size that will swallow the earth (fortunately for us that's a few billion years away from now).

It will burn as much fuel as it's size will allow then collapse in a far less spectacular way compared to a supernova and likely become a white dwarf. This smaller, hotter star will continue to burn until it runs out of steam.

There are so many different types of stars and so many different paths they can take from birth to death, that this website will offer you far more info than can be posted here:

Answer 5

It goes through stages, getting bigger, and bigger until it reaches the Red Giant Phase. Then eventually, its core will implode, and the star will explode or implode. Then there will be nothing left but a white dwarf, that will shine for about 1,00 years, and then eventually fade out of existance.

Answer 6

It dies and it blows up. It gets smaller when it gets older though. But only a lil bit smaller. Not like it reduces into nothing "smaller" and blows up. I mean mabye just a little bit in size. Nothing that you could notice.

Answer 7

well diferent types do different things. Some explode, some expand then contract and become white dwarfs and some become black holes

Answer 8

If it's a famous star, they get a star put on a sidewalk in Hollywood.

Answer 9

It gets plastic surgery and appears on The Surreal World.

Answer 10

it become a old star
