What is the difference between a planetary nebula and a nebula?

Yes. There is the Life-Cycle of Stars. The first stage is stellar nebula. Much later in the cycle is the planetary nebula; after the Red Giant, and before the White Dwarf.

A planetary nebula is the "out blast" of a star that has died, at the centre of the planetary nebula will the the stellar remnants of the propagator star - a white dwarf.

A cloud in outer space consisting of gas or dust and planetry nebula is one of the types also called ring nebula or A planetary nebula is an emission nebula consisting of a glowing shell of gas

Planetary nebula is a misnomer because it's a nebula but it has nothing to do with planets, it's about stars.

The Crab Nebula is a nebula.

The Cats's Eye Nebula is a perfect example of a planetary nebula. See related link for a pictorial.

most of the times a planetary nebula lives for 5,000 years

A star like our sun will shed a planetary nebula after its 'death'

a nebula is classified by a planetary nebulae

Planetary nebula is a misnomer because it's totally irrelevant to planets and it has something to do with stars. The short form is "nebula".

After a planetary nebula the oxygen in the middle will make it turn into a blackhole or neutron star.

A planetary nebula consists of gas ejected from old red giant stars.

a planetary nebula forms after a hsb o3iii

It does not exist. There are: Solar Nebula Planetary Nebula H Nebula Supernova Nebula (Supernova Remnant) Or just plain nebula.

A planetary nebula is the shell of a red giant, and the white dwarf is the core. As the red giant expands, the shell was blown into the space and became planetary nebula. After the formation of the planetary nebula, the hot core of the red giant was exposed and became a white dwarf.

The Stingray Nebula (Hen 3-1357) is a planetary nebula. (The youngest known).

The eye of god is a Helix nebula. Close to a Planetary nebula.

The planetarium nebula does not exist. If you mean Planetary Nebula then there are hundred if not thousands of them

a nebula is one nebula. nebulae are 2 or more nebulas.

A planetary nebula is created by a dying low to medium mass star as it sheds its outer layers of gas.

Both are the same except the solar nebula is the nebula that formed our solar system.

A solar nebula is related to the formation of our Solar System, any other nebula is just a nebula.

Depends entirely on the planetary nebula. A ball park figure would be around 50% of the mass of the progenitor star.

Yes. There are many planetary nebulae in our galaxy.

The galaxis are bigger than planetary nebulae, that are bigger than planetary systems.
