What happened when the gas in the nebula's center stopped collapsing?
When the gas in the nebula's center stopped collapsing, it likely reached a stable equilibrium where the inward force of gravity was balanced by the outward pressure from nuclear fusion or other energy sources. This equilibrium could result in the formation of a protostar or a star, depending on the mass and composition of the gas.
What is it called when the nebula begins collapsing and turning into a small spinning cloud?
This stage is called protostar formation. As the nebula collapses due to gravity, it begins to spin faster and forms a hot, dense core known as a protostar. This marks the beginning of the process that will eventually lead to the formation of a new star.
What are two opposing forces that stay balanced to keep a nebula from collapsing?
In a nebula, gravity and thermal pressure are two opposing forces that maintain balance. Gravity pulls the gas and dust inward, attempting to collapse the nebula, while thermal pressure, generated by the heat from the gas particles and any ongoing star formation, pushes outward. This equilibrium allows the nebula to remain stable for extended periods, preventing it from collapsing into a star or other celestial body. When these forces become unbalanced, it can lead to the formation of stars or other structures within the nebula.
What star sheds a planetary nebula?
A star like our sun will shed a planetary nebula after its 'death'
Where does most of a red giant go when the star becomes a white dwarf?
The white dwarf still has a lot of mass ( about 80% of the original star), but it only has a small size( less than two Earths). A huge volume of material forms a nebula which gradually disperses. This type of nebula is (confusingly) called a "planetary nebula".
Is a nebula a star?
a nebula is cloud of particles which forms into a star.

When the gas in the nebula's center stopped collapsing, it likely reached a stable equilibrium where the inward force of gravity was balanced by the outward pressure from nuclear fusion or other energy sources. This equilibrium could result in the formation of a protostar or a star, depending on the mass and composition of the gas.
When does a star form a nebula?
A star forms a nebula when it runs out of fuel. The star either becomes a red giant or a supergiant, then the star would be blown off into space either by expansion or explosion. The outer layers, which was released into space, would become a nebula, or sometimes a part of a larger nebula.
How many nebulas are needed to create a star?
Multiple nebulas are not needed to create a star. A star forms from the gravitational collapse of a single nebula, a region in space where gas and dust come together. The collapsing nebula undergoes fusion in its core to become a star.
What is a cloud of gas in which a star forms?
nebula.
What happens to material in the center of the nebula?
The material at the center of a nebula clumps together as material is pulled there. This allows a star to form.
How long does a star stay in a nebula?
A star does not "stay" in a nebula; rather, it forms within a nebula. A nebula is a vast cloud of gas and dust where star formation occurs, and the process can take millions of years. Once a star forms, it will eventually evolve and leave the nebula, transitioning into different stages of its lifecycle, such as a main-sequence star, red giant, or supernova, depending on its mass. Thus, a star is only associated with a nebula during the initial stages of its formation.
Is the Sun a star a planet or a nebula?
The Sun is a star, specifically a G-type main-sequence star, which is the star at the center of our solar system. It is not a planet or a nebula.
What is it called when the nebula begins collapsing and turning into a small spinning cloud?
This stage is called protostar formation. As the nebula collapses due to gravity, it begins to spin faster and forms a hot, dense core known as a protostar. This marks the beginning of the process that will eventually lead to the formation of a new star.
What material in the center of a nebula that becomes a star?
dust, tiny rocks.
What is material in the center of a nebula that becomes a star?

What two factors cause a nebula to develop into a star?
The two main factors that cause a nebula to develop into a star are gravity and heat. Gravity pulls the gas and dust in the nebula together, causing it to collapse under its own gravity. As the collapse continues, the temperature and pressure in the core of the collapsing nebula increase, eventually reaching a point where nuclear fusion ignites, and a star is born.
