The dying phase of a massive star begins when it runs out of usable hydrogen that it can convert to helium. Once it becomes a red giant, it slowly dies out.

How long does the main phase last in a massive star?
The more massive the shorter - down to just millions of years.
Is a supernova a type of galaxy?
No. A supernova is a massive explosion, usually from a dying supermassive star.
What if the biggest star went through a red giant phase?
The biggest star - VY Canis Majoris IS in a red supergiant phase and will explode as a massive supernova.
Is the lifetime of a massive star shorter or longer than a star like the sunwhy?
It is shorter because it uses the fuel faster and ends up dying faster.
Stages of star life in order?
1. Birth 2. Main sequence star phase 3. Deplation of hydrogen and helium fuel and expansion phase 4. Dying phase : either simple ejection of outer layers or explosion as a nova 5. Last phase : Black hole, neutron star or white dwarf
Is the sun a massive star or a dwarf star?
its not a massive or a dwarf star
What is a massive collapsed star?
A massive collapsed star is a dead star.
Are black holes born from dying planets?
No, planets are not nearly massive enough to become black holes. Any object with more than about 80 times the mass of Jupiter would begin fusing hydrogen in its core, so it would be a star, not a planet. Even then, it would still not be massive enough to form a black hole.
What is the early phase of the star called once the gas and dust begin to coalesce into a sphere?
It is called as a PROTOSTAR
Describe the life cycle of a very massive star from the red giant phase onward?
Stars that are massive enough are unlikely become red giants; instead they will destroy themselves as type II supernovas.
What is before a neutron star?
A normal (but fairly massive) star.A normal (but fairly massive) star.A normal (but fairly massive) star.A normal (but fairly massive) star.
At what stage in star development does a star spend most of its life?
A Star spends most of its life on the "main sequence" of the Hertzsprung-Russell diagram (see related link below). While here it is called a "main sequence" star and its source of energy during this phase of its life is the fusion of hydrogen into helium in its core.
