super giant.
Betelgeuse is currently in the red supergiant phase of its life cycle. It is near the end of its life and is expected to undergo a supernova explosion in the relatively near future (in astronomical timescales).
Unfortunately this is not true. Every project has an end and every project life cycle has an end too. The last phase of any projects life cycle is the project closure/closing phase where the project is wrapped up and closed.
No, a protostar is basically the BEGINNING of a star's life cycle.
A supernova occurs at the end of a massive star's life cycle.
The star will blow out its outer layers in a huge explosion called a supernova.
The turning points of the cycle are called the peak, which is at the end of the expansion phase, and the trough, which is at the end of the contraction phase.
The phase of silicon fusing into iron in a 25 solar mass star typically lasts for only a day or two before the star undergoes core collapse and a supernova explosion. This rapid process occurs at the end of the star's life cycle as it runs out of fuel to sustain nuclear fusion reactions.
No. Actually, it's heading to the end of it's life
Yes Star spend most of their life span as a main sequence star. A star end will depend on its size in life the end of a start can be a red giant to supernova, a white dwarf, pulsar, or black hole.
A red giant star is typically at the end of its life cycle. After exhausting its nuclear fuel, it expands and cools, becoming larger and brighter. Eventually, it may shed its outer layers, creating a planetary nebula, while the core remains and becomes a white dwarf. If the star is massive enough, it could instead end its life in a supernova explosion, leaving behind a neutron star or black hole.
Antares is farther along in its life cycle than the sun. Antares is a red supergiant star, which indicates that it is nearing the end of its life and will eventually explode as a supernova. The sun, on the other hand, is currently in its main sequence phase and has a few billion years of life left before it evolves into a red giant.
when a star is at the end of its life(depending on mass) a star will sponaniously explode into a supernova. or it will collapse into a black hole.
