Will Sirius become a supernova?

No, Sirius will not become a supernova. It is a relatively young star compared to those that typically go supernova, and its mass is not sufficient to trigger such an explosive event. Sirius is expected to eventually evolve into a white dwarf.


Will Sirius b become a supernova?

No. It's a white dwarf, meaning that it has no more fuel left for such things.


Will our sun become a red giant then will it become a supernova then a black hole?

No, our sun is not destined to become a supernova and/or a black hole. It will become a red giant, but it is not massive enough to cross the threshold and become a candidate for a fate like either of those last two.


Could a supernova on Jupiter cause the earth to be pushed off it axis?

Only a very, very few stars have mass enough to become supernova. Jupiter is a planet not a star. It is far to small to become a star, let alone a supernova.


Why do some stars become red giants and others become supernova?

What 2 things can happen to a star after a supernova?

It can either become a neutron star or a black hole. If the star is between 8 and 15 solar masses, it will become an incredibly dense neutron star. If it is more than 15 solar masses, it will collapse and become an even denser black hole.


Why do all stars end in a supernova?

Oops! Not all stars end up as a supernova. To become a Type 2 supernova, the star has to be between 8 and 50 times larger than the Sun.


Will the sun turn into a super nova?

No. It does not have enough mass to become a supernova.


Will Altair soon become a supernova?

Highly unlikely in our lifetime. Altair is still on the main sequence and probably has a few billion years left on it. Even when it comes to the end of the main sequence, it may not have enough mass to become a supernova.


What happens to a burnt out star?

If it's a big enough explosion it will become a supernova


When was the last supernova explosion?

Because of the distances involved, a supernova could have occured today, but we wouldn't know about it for thousands or billions of years. As with all things in space, what we observe is what was, not what is.See related questions for last observed supernova.


What happens to stars as they increase the percentage of metal they have in them?

Among other things, they will have less fuel available. Eventually, a star will become unstable and convert into a giant star, or even blow up as a supernova.
