Nebulae are made of dust and gases—mostly hydrogen and helium. The dust and gases in a nebula are very spread out, but gravity can slowly begin to pull together clumps of dust and gas. As these clumps get bigger and bigger, their gravity gets stronger and stronger.

WebStar Formation. Stars are born within the clouds of dust and scattered throughout most galaxies. A familiar example of such as a dust cloud is the Orion Nebula. Turbulence deep … WebFor example, the ‘normal star’ stage is a period when vigorous activity between strenuously opposed gravity and motion produces little moment-to-moment change. Cool nebulae make ideal stellar nurseries because the gas pressure in them is low. Gravitational collapse inside such nebulae begins when suﬃciently dense regions develop.
