A nebula forms into a star through a process called stellar formation, which begins when regions within the nebula, often composed of gas and dust, collapse under their own gravitational pull. As the material condenses, it heats up, forming a protostar at the center. Once the core temperature is sufficiently high, nuclear fusion ignites, converting hydrogen into helium and releasing energy, which marks the birth of a new star. Over time, the star stabilizes and enters the main sequence phase of its life cycle.

What distinguishes a nebula and a star?
A nebula is a cloud of substances and gases that can form into a star. A star is a ball of hydrogen and helium with trace amounts of other gases. A supernova is the death of a star.
What does the core of a star do when it blows its surface into space to form a planetary nebula?
When the core of a star blows its surface into space to form a planetary nebula, it sheds its outer layers of gas, exposing the hot, dense core of the star called a white dwarf. The white dwarf emits ultraviolet radiation that ionizes the ejected gas, causing it to glow and form the planetary nebula.
What type of star is Andromeda?
Andromeda is not a star. It is a constellation. But it is also the name, given in short form, to the Andromeda Nebula.
What stage is a nebula?
a stage in a star's life? it is the very first stage in a star's life. a nebula occurs, which is a cloud of dust or gases, then depending on the mass of the star, it goes either to a giant or a super giant.
What must a nebula contain for the materials in it combine and form a new star?
Lots of hydrogen
What is after a nebula in a star life?
A nebula may condense and ignite to become a star, conversely a star may explode and form a nebula.
Another name for the interstellar matter that will eventually form a star is?
protostar or nebula
What is the gas and dust that contracts to form a star?
A nebula.
Do nebula's die?
Yes, Nebula's die. They die when they get to close to Black Holes.
What distinguishes a nebula and a star?
A nebula is a cloud of substances and gases that can form into a star. A star is a ball of hydrogen and helium with trace amounts of other gases. A supernova is the death of a star.
Is planet nebula real?
The correct term is planetary nebula. Such nebulae form when a low to medium mass star dies.
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.
What does the core of a star do when it blows its surface into space to form a planetary nebula?

The white dwarf emits ultraviolet radiation that ionizes the ejected gas, causing it to glow and form the planetary nebula.
Is a nebula a star?
a nebula is cloud of particles which forms into a star.
Why did the world come to be?
It condensed from the interstellar nebula form which our star, the Sun, was formed.
