A nebula is the initial stage in the lifecycle of a star, a vast cloud of gas and dust in space where stars are born. Gravity causes regions within the nebula to contract and form protostars, which eventually grow into full-fledged stars. Nebulas are the birthplaces of stars in the cosmos.
a stage in a star's life? it is the very first stage in a star's life. a nebula occurs, which is a cloud of dust or gases, then depending on the mass of the star, it goes either to a giant or a super giant.
Protostar Stage
A nebula is a cloud of gas (hydrogen) and dust in space. Nebulae are the birthplaces of stars.
Triffid Nebula, Eagle Nebula, Cat's Eye nebula
A nebula is an interstellar cloud of dust, hydrogen gas and plasma. It is the first stage of a star's cycle.
Emission nebula glow and reflection nebula reflect the light form other stars
Protostar Stage
The first stage of stellar evolution is nebula.
stellar nebula
It doesn't differ from a star, it is a star and it is the second stage in a stars life after the nebula stage.
The first stage in a star's life is as a nebula. As the gravitational forces spin faster, the star enters it's second stage, that of a prostar.
A star is "born" in a large cloud of dust and gas called a nebula

The Crab Nebula is a nebula.
It will not, at least not on its own. NGC 6720 is not the sort of nebula that produces new stars; it is a planetary nebula formed from the gasses expelled from a dying star. At its center is a remnant called a white dwarf.
