A stellar nebula can vary greatly in size, typically ranging from a few light-years to several hundred light-years across. These vast clouds of gas and dust serve as the birthplaces of stars and can contain a mix of hydrogen, helium, and other elements. The size and density of a nebula influence star formation processes, with denser regions often collapsing under gravity to form new stars.
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
it is not the it is a stellar nebula considering that there are multiple stellar nebulas in the universe. what a steller nebula is though is dust and such maing a nebula then when the nebula is strong enough to make a star is creates a prostar, then it is either a massive star or a non massive star. soon they will either turn into a super giant or a red giant. then either the star will explode or simply poof then either it is a white dwarf a neutron star or a black hole. the end
I don't really know but the density level is 10.54
A stellar nebula, often referred to as a primordial or star-forming nebula, is a vast cloud of gas and dust where new stars are born. In contrast, a planetary nebula is formed from the outer layers of a dying star, typically a medium-sized star, that have been expelled into space after the star has exhausted its nuclear fuel and shed its outer envelope. While stellar nebulae are associated with the birth of stars, planetary nebulae signify the end stages of a star's lifecycle.
High pressure in a nebula can lead to increased gravitational forces, which may compress the gas and dust within it, potentially reducing its overall size. This compression can trigger processes such as star formation, as regions of higher density collapse under their own gravity. Consequently, regions within the nebula may become more compact, while the nebula as a whole could appear smaller as material coalesces into new stellar bodies.
The first stage of stellar evolution is nebula.

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

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.
It is sometimes called the Solar nebula.

It is called a Nebula (nebulae for plural). no sorry but your wrong it is a coma It can be both it just depends. The question needs to be more specific
A "proto-star".
