A planetary nebula primarily consists of hydrogen and helium, which are the most abundant elements in the universe. Additionally, it may contain trace amounts of other elements such as carbon, nitrogen, oxygen, and neon, ejected from the dying star during its asymptotic giant branch phase. The gases are often ionized, giving rise to the nebula's characteristic colors as they emit light.

The Orion Nebula (M42) is one of the most famous and brightest nebulas in the night sky. It is a stellar nursery where new stars are forming and is visible to the naked eye in the constellation of Orion.
A nebula does not directly turn into a white dwarf. A nebula will collapse to form stars. Low to medium mass stars become white dwarfs after they die. Some are the result of a supernova and do not collapse, they merely dissipate over time. The Crab Nebula is the most prominent example of this.
An ionization nebula is typically found in regions where there are hot, massive stars that emit high-energy ultraviolet radiation. These nebulae are commonly located in the spiral arms of galaxies, near star-forming regions or in clusters of young, hot stars.
No. The most fundamental parts of matter are: quarks and electrons.
A stellar nebula can exist for millions to billions of years, depending on the size and mass of the nebula. These nebulae are the birthplaces of stars and can last until all the matter within them has been used up in the process of star formation.
The crab nebula is the debris formed in the supernova explosion.

You can find a Nebula just about anywhere in space. They are big floating masses of dust and gas that form stars.

Nebula used to be the most powerful fairy, but when Bloom came, she became weak.
More than 74% of the matter in the universe is hydrogen, so when a star forms and collects surrounding matter most of that matter will be hydrogen. It is a simple matter of the availability of different elements.
