The term "planetary nebula" is a bit misleading - it is a blob of glowing gas which expands from red giant stars late in their lives, thought to be pushed out from the outer layers of the stars by their stellar wind. There is a chance some planets may have been around at the time of the expansion, but that is by no means mandatory nor really indicative of the origin of the name.
New planets are found in other planetary systems almost weekly.

The galaxis are bigger than planetary nebulae, that are bigger than planetary systems.
This is false. The first ingredient is God.
