After a nebula, a star's life cycle progresses to the formation of a protostar, where gravitational forces cause the gas and dust to collapse and heat up. As the protostar continues to accumulate mass, it eventually reaches temperatures and pressures sufficient for nuclear fusion to ignite in its core, marking the transition to the main sequence phase of a star's life. Depending on its mass, the star will then evolve through various stages, ultimately leading to its end state, which could be a red giant, supernova, or a white dwarf, neutron star, or black hole.

What do scientists call the gas around a star at the end of its life cycle that will change into a new star?
The gas surrounding a star at the end of its life cycle is called a "nebula." This nebula is composed of gas and dust that can eventually condense under gravity to form new stars. The process of star formation from a nebula involves the collapse of these materials, leading to the birth of new stars and planetary systems.
How does the life cycle of a star differ between one that is born from a large nebula as opposed to one born in a very large nebula?
None at all/ The life cycle of a star is based on it's initial mass, not where it was formed.
What are the star life cycle that are accurate?
The stages in a star's life cycle are: formation from a nebula, main sequence (where it fuses hydrogen into helium), red giant or supergiant phase, depending on the star's mass, and finally either collapse into a white dwarf, neutron star, or black hole. This life cycle is accurate for most stars, including our Sun.
What is a star is born whenever a nebula expands?
A star is born when a nebula, a vast cloud of gas and dust in space, undergoes gravitational collapse. As the nebula contracts, the material within it becomes denser, leading to increased temperatures and pressure at its core. Once the conditions are right, nuclear fusion ignites, marking the birth of a new star. This process illustrates the life cycle of stars, where stellar formation begins from the remnants of previous stars.
Define the terms supernova and nebula?
A supernova is a powerful stellar explosion that occurs at the end of a star's life cycle, leading to a burst of radiation and the creation of heavy elements. A nebula is a vast cloud of gas and dust in space, often formed from the remnants of dying stars or regions where new stars are being born.
Where do all-stars begin their life cycle?
In the nebula!
What is in the first stage in a stars life cycle?
A nebula is a cloud of gas (hydrogen) and dust in space. Nebulae are the birthplaces of stars.
Whats the life cycle of the stars?
A star's life cycle starts from a nebula. For giant stars, the star turns into a huge star to a super red giant to a supernova to a black hole. A sun-like star turns to a red giant, then a planetary nebula, a white dwarf, and then a black dwarf.
What the first stage in a star life cycle?
A nebula is a cloud of gas (hydrogen) and dust in space. Nebulae are the birthplaces of stars.
What is the difference of a nebula and a supernova?
A nebula contains stars and other matter; a supernova is just a large enough nova, or star that explodes at the end of its life cycle due to spent fuel
Where do star begin their life cycle?
Stars begin their life cycles in a nebula.
How is a nebula linked to a black hole?
When a nebula collapses under the right conditions it forms a star. Larger stars end their life-cycle as black holes. For more information try searching for "stellar evolution."
What is the first stage in the life cycle of a star?
stellar nebula
How does the life cycle of a star differ between one that is born from a large nebula as opposed to one born in a very large nebula?
None at all/ The life cycle of a star is based on it's initial mass, not where it was formed.
How long does it take before a nebula turns into a protostar?
A star life cycle takes millions of years. Some stars even last for billions of years, which can be older than our universe.
What are the star life cycle that are accurate?
The stages in a star's life cycle are: formation from a nebula, main sequence (where it fuses hydrogen into helium), red giant or supergiant phase, depending on the star's mass, and finally either collapse into a white dwarf, neutron star, or black hole. This life cycle is accurate for most stars, including our Sun.
What is the first stage in a star's life cycle?
The first stage in a star's life cycle is the nebula stage, where a cloud of gas and dust in space begins to collapse under its own gravity. This collapse leads to the formation of a protostar, which will eventually become a full-fledged star through nuclear fusion.
