A galaxy is a massive, gravitationally bound system that consists of stars and stellar remnants interspersed with a medium of gas, dust, and dark matter.
A nebula is an interstellar cloud of dust, hydrogen, helium and other gases.
However, in some older astronomy literature, all "fuzzy objects" were called nebula, even if they were technically galaxies. This is because scientists had not yet established that galaxies were, in fact, objects outside the Milky Way.
They were presumed to be among the local gas & dust objects in our own galaxy. Edwin Hubble made the essential determination that some "nebulae" were considerably further away than other objects in the milky way and were, in fact, separate galaxies.
The main difference between the nebular and condensation theories is their emphasis on different aspects of planet formation. Nebular theory focuses on the collapse of a rotating nebula to form a star and planets, while condensation theory emphasizes the role of solid particles (dust and gas) in the early stages of planet formation.
It is not known how big a stellar nebula, but they are extremely huge. Some stretch over hundreds of light years across and they are the 'birthplace' of stars
Emission nebula glow and reflection nebula reflect the light form other stars

The nebular model explains how our solar system formed from a rotating cloud of gas and dust called a solar nebula. Gravity caused the nebula to collapse, forming a central protostar surrounded by a spinning disk. Over time, the material in the disk clumped together to form planets and other solar system bodies.
'Nebular' means 'like a nebula'. - A nebula is a diffuse mass of interstellar dust or gas or both, visible as luminous patches.

The first stage of stellar evolution is nebula.

A stellar nursery is usually called a molecular cloud. A nebula is a generic term for an interstellar cloud of dust, gas and plasma.

it is plop of a difference
stellar nebula
stellar nebulas are the birthplace of stars. 1st of the sequence in the lifecycle of stars.
The Crab Nebula is the remains of a supernova that was observed in 1054.It is the stellar remnants of a star that exploded thousands of years ago.I've not heard of it being referred to as a "stellar graveyard" but I guess it is because of the death of the host star.
