A galaxy.
The answer is simple: gravity.

Is called a galaxy
Yes, that's correct! Stars are born when gravity causes gas and dust in a molecular cloud to collapse under their own weight. This collapse creates high pressures and temperatures in the core of the forming star, eventually igniting nuclear fusion and creating a stable star.
Yes, a nebula is held together by gravity. Gravity causes the gas and dust within a nebula to contract and clump together, eventually forming stars and other celestial bodies.

A galaxy is a big assembly of stars, gas, and dust that is held together by gravity. They come in different shapes and sizes and contain billions to trillions of stars. Our own galaxy is called the Milky Way.
Gravity - from the stars, dust, etc., but especially from "dark matter", a substance of yet unknown composition.
A group of stars, gas, and dust held together by gravity is known as a galaxy. Galaxies come in various shapes and sizes and can contain billions to trillions of stars. Our own galaxy, the Milky Way, is a spiral galaxy containing around 100-400 billion stars. The gravitational forces within a galaxy keep its components bound together in a cohesive structure.
This represents a galaxy, which is a massive collection of stars, gas, dust, and other celestial objects bound together by gravity. The Milky Way is an example of a galaxy that contains millions of stars, along with interstellar gas and dust.
A nebula IS a cloud of dust and gas loosely held together by gravity.
Yes, that's correct! Stars are born when gravity causes gas and dust in a molecular cloud to collapse under their own weight. This collapse creates high pressures and temperatures in the core of the forming star, eventually igniting nuclear fusion and creating a stable star.
