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.

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.


Which constellation has the star Altair?

Altair is the brightest star in the Aquila constellation.


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.


When will eta carinae go supernova?

An excellent question, but without a good answer. Eta Carina is one of the most massive stars that we know of (yet), with a mass upwards of 100 solar masses. Very massive stars live fast and die young, so we expect it to become a supernova "relatively soon", but "relatively soon" to an astronomer means "Between 10,000 years and 1,000,000 years from now". There is no indication that this event is going to happen within our lifetimes, although at 8,000 light years away, it's possible that we just didn't notice. At that mass, its ultimate fate is most probably to become a black hole.


The onset of iron fusion causes a star to become a?

The onset of iron fusion causes a star to become a supernova. This process occurs when the star's core collapses due to the inability to support the fusion of iron, leading to a catastrophic explosion.
