What would happen if a super nova hit earth?
A supernova is an exploding star. The Earth would be instantly incinerated, of course. There is approximately zero chance this will ever happen, though. If there was a supernova near Earth ... it would depend on how near. Betelgeuse is a good candidate for a supernova "soon" (within the next million years or so). Scientists who have modeled supernova explosions don't expect it will have much of an impact. If a star nearer than Betelgeuse were to go supernova, then it might be more serious.
A star 30 times larger than the sun will turn into?
A star 30 times the mass of our Sun will quickly exhaust its hydrogen, go supernova and probably form a "black hole".
What happens to a star when it runs out of fuel?
To start from the beginning, a stars "fuel" is initially H, or hydrogen the lightest element. A star is basically a nuclear reactor and fuses the H molecules together to form He or helium (this process is called fusion) depending on the size of the star, it can fuse heavier and heavier elements and if you have a really big star it will make iron from fusion or a little star will burn out extremely slowly and make a brown dwarf. A big star could do a lot of things. It could go supernova and eventually form a black hole or it could become a quasar, to a few other things.
How far is the closest star to earth?
The closest supernova, or more correctly supernova remnant, is the Vela supernova remnant [See Link] in the constellation Vela. The "guest" star exploded about 11 - 12,000 years ago and is located around 800 light years from Earth.
What property of star determine the stages it will go through during its life cycle?
The size of the star
Will a very large star go through several supernova explosions in its lifetime?
A star will become a supernova only once.However, a white dwarf can have multiple novaeruptions.See related questions
When will the sun be supernova?
Never. A star must be about 10 times the mass of the sun or more to go supernova.
Which star has the greatest probability of producing a supernova explosion?
There is no way of knowing which star will next go "supernova".However, closer to home, Betelgeuse is the most likely to produce a supernova - within humanities lifetime.
The explosion of a very massive star is called what?
well what you gotta do is go home a smoke weed
What is the difference between a nova a supernova and a neutron star?
A nova is a star which has a close companion star, and draws stellar material off of it's companion, occasionally flaring up very brightly in the process. A supernova is a massive and hot star to begin with, that tends to go through it's life cycle at high speed, and ending it's life in a cataclysmic explosion. Supernova remnants then collapse into a neutron star - a spinning, very hot pile of stellar ash, so dense that a teaspoonful of it would weigh thousands of tons. If the collapsed supernova star was big enough, it's gravity upon collapse is so intense than not even light can escape from it, and it becomes what is called a "Black Hole".
What kind of star is most likely to become a white-dwarf supernova?
A supernova is a star that has exploded into dust and gas. A white-dwarf is a small, hot, dense star nearing the end of its life, that did not have enough mass to go supernova. So the answer is "none".
When will a star go supernova?
Currently, there is no real way of knowing when a star will go supernova within a few thousand to million years. There are signs, that a star will go supernova based on physics and observations but WHEN is a problem. A star will "pulse" in a "last breath" prior to going supernova, but like death itself, no one really knows, when that last breath will happen. Betelgeuse, is experiencing those "last breaths" but when it will happen, or has happened, we will not know until we see the brilleint outburst from Earth.
Will a neutron star eventually go supernova?
No. A neutron star is left behind after a supernova. However, some gamma ray bursts may result from a collision between neutron stars.
What is one of the endings of a star?
Under certain conditions, a large star can go supernova, and blast itself to smithereens. Our star (Sol, or Sun) cannot go supernova unless it would somehow 'capture' a white dwarf. This would be billions of years from now, so don't worry.
What is important about the color of the stars?
the color of the stars usually determines how old and how hot the star is it can also determine when the star will go supernova
Is a star going supernova in the Orion?
It's quite possible that we MAY see Betelgeuse go supernova. It may have already happened but as the star is over 600 light years away, the light will take a while to reach us.
What is the ''life'' cycle of stars?
Stars form from dust and gas known as stellar nebula. Then the star (depending on its type) will go on to live out its life. In its dying stage it either turns into a red giant or a red super giant. Then the star will either go through a planetary nebula or will go supernova. Afterwards the star will either turn into a white dwarf, a neutron star, or a black hole.
