A planetary nebula is a glowing shell of gas and dust formed by a star shedding its outer layers at the end of its life. Despite its name, it has nothing to do with planets. The glowing gas is illuminated by the hot core of the star left behind, known as a white dwarf.
A nebula is a cloud of gas and dust in space where new stars are formed. These regions are often characterized by the presence of young, hot stars surrounded by glowing gas and dark dust.
A large cloud of gas and dust from which stars are formed is called a nebula. Within a nebula, gravity causes the gas and dust to come together, forming clumps that eventually collapse to create new stars. Nebulae are often seen as glowing or dark patches in the night sky.
When a planetary nebula dissipates, what remains is the core of the star that has shed its outer layers. This core, known as a white dwarf, is extremely dense and hot, gradually cooling over billions of years. The planetary nebula itself, which is the glowing gas and dust expelled by the dying star, eventually disperses into space.

Nebula
A glowing cloud of gas is typically a nebula, which is a large cloud of gas and dust in space that emits light due to the presence of energized atoms and molecules. These clouds can be illuminated by nearby stars or by processes such as shockwaves or radiation from massive stars.

in the middle of a nebula lies a glowing neutron star or a white dwarf with highly concentrated mass at extremely high densities.

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

The explosion (a supernova) produces a glowing cloud of gas (called a nebula) that slowly expands and dissipates (eg the crab nebula).
