Because stellar means star& and nebulae create stars.
Stars are often born in nebulae composed of interstellar gases called stellar nurseries.
The dense gaseous nebulae where star formation occurs are called "stellar nurseries." A star may begin to coalesce due to gravitational disturbances that compress the gases of the nebula.
Becuase it provides a place for animal to live a grow up.
Molecular clouds are interstellar clouds whose size and density permits the formation of molecules. Molecular clouds are called Stellar Nurseries if a star formation is occuring within it.
It is sometimes called the Solar nebula.
The infant nurseries are called the hatcheries.
Clouds of gas and dust from which stars form are called interstellar matter.
Clouds of gas and dust, called nebulas and then form into protostars.
Stars form from collapsing clouds of dust and gas within regions of molecular clouds, often called stellar nurseries. As the cloud collapses its density and temperature increase until it eventually reaches the point where a start begins to form in the center of the cloud.
A stellar source of periodic radio signals is called quasar. This runs off of radio waves.
A star nursery is called a "stellar nursery" or a "stellar birthplace." These are regions in space where new stars are formed from collapsing clouds of gas and dust.
Becuase it provides a place for animal to live a grow up.
