Interstellar gas is inelastic. To compress it some event typically must occur. A supernova, for example, produces a shockwave that collapses interstellar gas, precipitating nearby star formation. Another force is gravity--we have seen stars form in the swirling wake of passing black holes.
When two nebula collide, we might infer star formation across the "impact zone," much as water droplets precipitate when a moist warm air mass collides with a cooler, denser mass of air.
The birthplace for stars is called a stellar nursery. These nurseries are regions within galaxies where gas and dust condense to form new stars.
This describes a nebula, which is a vast cloud of gas and dust in space where stars are born. The gases and dust within a nebula are the raw materials that eventually come together under gravity to form new stars.
Yes, a nebula can be much larger in size than a star. Nebulae are vast clouds of gas and dust in space, while stars are relatively small and compact objects that form within these nebulae. Some nebulae can span hundreds of light-years across, whereas stars are typically only a few times the size of Earth.
Two types of stars that can form from a nebula are main sequence stars, like our sun, and giant stars, which are larger and more luminous than main sequence stars.
Gravity is the force that causes nebulae to collapse. As particles within the nebula are pulled together by gravity, they begin to clump and form denser regions. This leads to the eventual formation of stars and planetary systems within the collapsing nebula.
Stars form from the matter within nebula.

If the nebula is gravitationally unstable, it collapsing & forming stars!

Emission nebula glow and reflection nebula reflect the light form other stars
The Nebula Cloud theory is more widely accepted and supported by evidence compared to the Passing Star theory. The Nebula Cloud theory suggests that stars form within nebulas, while the Passing Star theory proposes that stars are formed by interactions with other stars.
Nebula
Planetary nebula is a misnomer because it's totally irrelevant to planets and it has something to do with stars. The short form is "nebula".
The Orion Nebula is called a star nursery because it is a region within our galaxy where new stars are actively forming. The nebula is a giant cloud of gas and dust where gravity causes these materials to come together and eventually form new stars. This process of star formation resembles a nursery where new stars are born.
