If enough matter comes together close enough, the collapse itself will generate enough heat (and pressure) for nuclear fusion. In other words, a star is created.
A star like our sun will shed a planetary nebula after its 'death'
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".
Yes. The Crab Nebula neutron star. A neutron star found in the middle of the Crab Nebula - a Nebula formed from the 1054 supernova event.
nebula
Yes, Nebula's die. They die when they get to close to Black Holes.
a nebula is cloud of particles which forms into a star.
nebula.
The material at the center of a nebula clumps together as material is pulled there. This allows a star to form.
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.
dust, tiny rocks.
dust, tiny rocks.
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.
A "proto-star".
A nebula may condense and ignite to become a star, conversely a star may explode and form a nebula.
A White Dwarf Star remains.
A Nebula is a gas of dust and minerals that surrounds a star. Also, a nebula is a birthplace of a star, where a star and sometimes a solar system is formed after a huge explosions
