The Cats's Eye Nebula is a perfect example of a planetary nebula.

No, the Sun is not a planetary nebula; it is a main-sequence star. A planetary nebula is a stage in the life cycle of certain stars, typically those with a mass similar to or less than that of the Sun, that occurs after they exhaust their nuclear fuel and expel their outer layers. The Sun will eventually become a red giant and then evolve into a planetary nebula in about 5 billion years, but currently, it is still in the main-sequence phase of its life.
The Eskimo Nebula, also known as NGC 2392, is a planetary nebula located in the constellation Gemini. It is significant because its distinctive shape resembles a face surrounded by a parka hood, giving rise to its popular name. The Eskimo Nebula is of interest to astronomers for studying the late stages of stellar evolution and the creation of planetary nebulae.
Planetary nebulae can vary in color, but they are typically seen as shades of green, blue, or red. These colors are produced by different gases in the nebula interacting with light from the central star.
A planetary nebula is created when a low- to medium-mass star reaches the end of its life cycle and sheds its outer layers of gas into space. This process exposes the hot core of the star, which emits ultraviolet radiation that causes the surrounding gas to glow and form a colorful nebula.
Planetary nebula is a misnomer because it's a nebula but it has nothing to do with planets, it's about stars.
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
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.
Yes. There are many planetary nebulae in our galaxy.

The Helix Nebula is a planetary nebula located in the constellation Aquarius, while the Ring Nebula is a planetary nebula located in the constellation Lyra. The Helix Nebula appears more like a disk or helix shape, while the Ring Nebula appears as a ring or donut shape due to its orientation.
