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.

Can a nebula be bigger than a star?
Yes. Stars form within a nebula.
What is the difference between a emission nebula and a reflection nebula?
Emission nebula glow and reflection nebula reflect the light form other stars
What 2 types of stars can form from a nebula?
non
Stars are formed from clouds of dust and gas called?
Stars. That is how stars are formed. They form from nebulae.
What stage is a nebula?
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.
What do stars form from?
Stars form from the matter within nebula.
Can a nebula be bigger than a star?
Yes. Stars form within a nebula.
Why did the nebula's condense to form the sun?
If the nebula is gravitationally unstable, it collapsing & forming stars!
What is the difference between a emission nebula and a reflection nebula?
Emission nebula glow and reflection nebula reflect the light form other stars
What 2 types of stars can form from a nebula?
non
What is A huge cloud of gas and dust in which stars form?
Nebula
Why is planetary nebula a misnomer?
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".

Was the Orion nebula a nova or a supernova?
The Orion nebula was likely caused by a supernova. It is a huge cloud of gas within which hundreds of new stars are being formed.
What two types of stars that can form from nebula?
Any star can form from a nebula. all it needs is some force to make it collapse, like a nearby supernova or gravitational pull.
How are nebulae formed?
Nebula are formed when a star explodes, releasing its gas into a gas cloud (the nebula). the nebula then will eventually condense due to gravity and form another star.
