A star like our sun will shed a planetary nebula after its 'death'
Planetary Nebula
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.
most of the times a planetary nebula lives for 5,000 years
A Planetary Nebula
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".
A planetary nebula is created by a dying low to medium mass star as it sheds its outer layers of gas.
After a planetary nebula the oxygen in the middle will make it turn into a blackhole or neutron star.
A White Dwarf Star remains.
It becomes a white dwarf.
Planetary Nebula
The correct term is planetary nebula. Such nebulae form when a low to medium mass star dies.

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

Typically it is called a planetary nebula. It has nothing to do with planets.
