"Super Nova " . I heard the last day that it's the time that the star can't keep living ! Why ?

Question

Could it happen to the Earth ?

Folks , the answer of " chris " is intresting ; I hope you read it !

Answer 1

they happen because the star burns itself out...it uses up all the hydrogen for fuel.
no it can't happen to earth because earth is not a star...it also will not happen to the sun (which is a star).

so what will happen?
according to: http://open-encyclopedia.com/Sun
"Our sun does not have the mass to Nova or Supernova. However in 4-5 billion years it will enter its red giant phase, expanding as the hydrogen fuel in the core is consumed and it starts to burn heavier elements that are present. While it is likely that this expansion will reach the current position of Earth's orbit, recent research suggests that mass loss from the Sun earlier in its red giant phase will cause the Earth's orbit to move further out, preventing it from being swallowed. Following the red giant phase, the Sun will become a white dwarf, slowly cooling for a further 5 billion years or so."

Answer 2

Supernovas happen to big stars, much bigger than the sun, when they exhaust all their fuel and the fusion process reaches iron, after that fusion needs more energy than the gravitational force of this massive star and the star explodes releasing all those elements in space, to become included in the material making new stars (and planets.) That is exactly how life came to be since we need more than simple hydrogen to make amino-acids. Naturally this will never happen to earth, earth is only a planet and the sun is too small to become a nova or supernova. The sun will end up a white dwarf then a brown dwarf. The process of star birth and death is well known now so get a good astronomy book, it is fascinating but the topic is too big to explain on Yahoo Answers.

Answer 3

Supernovas only happen to big stars. The Sun is not a big star, so unless a whole lot of hydrogen falls into it at some point (and that is EXTREMELY unlikely), it will not go through a supernova. It will, however, go through a standard nova, expanding into a red giant and baking the three inner planets, in about 5000000000 years' time, but you don't have to worry about that. The Earth cannot explode on its own, because it is not a star and does not fuse hydrogen.

Answer 4

True. When a star has used up all its resources it will eventually die in a number of ways. Our sun will eventually do this. When all the resources have been used up the Sun will turn into a massive Red star. It will expand so much it will consume Mercury, Venus, Earth, and Mars. We will die instantly and never know what happened. The Sun will then compacted down quickly and explode into a violent Supernova. It will then resume its life as a dwarf star procing nothing of value to the remaining solar system.

Answer 5

No. The earth is a planet and cannot Implode and the sun our closest star is too small to Implode and cause a Super nova.

Answer 6

a super nova is when a star blows up

Answer 7

Because it is too old of heart! It could happen to the sun!

Answer 8

What?
