Best Answer

It depends on the initial mass of the star - i.e., how much actual material it contains. The more massive a star is, the shorter its 'life'. Most stars average out at roughly the mass of the Sun (certainly within a fairly narrow range either side of it at least) and the lifetime for such stars is therefore about the same as the Sun's - about 10 billion years. Really massive stars like eta Carinae will run through their nuclear reactions at a much faster rate and so will only last for a few million years. Eta Carinae could go supernova any day now!

Do stars explode?

Some stars do. They can be nova or supernova stars, depending on the scale of the explosion.


What is it called when stars in the sky die?

Some stars explode in a supernova.


Which stars are hotter red stars or blue stars?

Blue stars are the hottest, because they are newborn stars. Yellow stars are medium age stars, like our sun, and are right in the middle. Red stars are the oldest, and will explode very soon, so those are the coolest (but still pretty hot; hotter than your oven!).


What is the space in space called after a star explode?

well it depends on the star. not all stars explode. small to medium sized stars just go into a planetary nebula after they swell up to a red giant then the bigger stars do explode, they have a super nova after the swell up into a super giant. but dont worry i star will not explode... its a really small star. --- nichole brooks :)


How does the future of massive stars differ from the future of smaller stars?

Massive stars are most likely to explode faster than smaller stars.


Do stars let off radiation waves when they explode?

Yes.


What will happen if VTS352's two stars do not merge and explode separately?

I believe the idea here is that the stars are more likely to explode as a result of a merger.If one of the stars explodes before that... Well, in general, if one star in a binary system explodes, you can expect part of the matter to pass over to the other star, as a result to its gravitational attraction. This in turn may make the remaining star explode sooner than it would otherwise - perhaps almost immediately, depending on the exact situation.


How does a star run out of gas then causing it to explode?

OK maybe when is runs out of gas all the gas around it will explode because the heat of the star too. so that is why the stars explode
