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.
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 force causes a star to form from a nebula?
A star forms from a nebula primarily due to gravitational forces. As regions within the nebula contract under their own gravity, the material becomes denser and hotter, leading to the formation of a protostar. When the core temperature and pressure become sufficient for nuclear fusion to initiate, a star is born. This process is often triggered by external factors such as nearby supernova explosions or shock waves from other celestial events that compress the gas and dust in the nebula.
What happens to the core of a star after a planetary nebula occurs?
After a planetary nebula occurs, the core of the star collapses and becomes a white dwarf. This white dwarf slowly cools down over billions of years until it eventually becomes a cold, dark remnant known as a black dwarf.
What is the connection between pulsars and the Crab Nebula?
Pulsars were discovered in the Crab Nebula, a supernova remnant, in 1967. The Crab Pulsar is a neutron star at the center of the nebula that emits beams of radiation, producing regular pulses of light. The high-energy particles and magnetic fields in the nebula power the pulsar's emission.
What material in the center of a nebula that becomes a star?
dust, tiny rocks.
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.
Why is the center of a collapsing nebula forms a star?
When a nebula collapses due to gravitational forces, the center becomes denser and hotter. As the material in the center becomes more compact, the pressure and temperature increase, eventually triggering nuclear fusion reactions that sustain a star's energy. This marks the birth of a new star in the center of the collapsing nebula.
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.
What is matter from a nebula that has begun to condense under the weight of gravity to begin the formation of a star?
This stage is called protostar formation, where the material in a nebula begins to collapse and accumulate due to gravity. As more matter collects at the center, it becomes denser and hotter, eventually triggering nuclear fusion and leading to the birth of a star.
What order does a nebula occur and becomes a main sequence star and then a giant?
main sequence,giant then nebula
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.
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".
What is the dense center of a stellar nebula after it spins into a disk shape?
A "proto-star".
What force causes a star to form from a nebula?
A star forms from a nebula primarily due to gravitational forces. As regions within the nebula contract under their own gravity, the material becomes denser and hotter, leading to the formation of a protostar. When the core temperature and pressure become sufficient for nuclear fusion to initiate, a star is born.

How was the boomerang nebula formed?
The Boomerang Nebula is a planetary nebula [See related question]. It would have been formed when a medium sized star came to the end of it's life and in that process shed off layers of material from the star. This created the nebula we see today.
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.
