Is called a galaxy
The answer is simple: gravity.
A galaxy.
a galexy
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.
A system of stars, gases, dust, and other matter that orbits a common center of gravity is known as a galaxy. Galaxies can vary in size and structure, containing billions to trillions of stars and vast amounts of interstellar material. They are held together by gravitational forces and can include various components such as star clusters, nebulae, and dark matter. The Milky Way is an example of a spiral galaxy that contains our solar system.
The answer is simple: gravity.
Galaxy
A galaxy.
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.
That is a galaxy.

A galaxy
A very large system of stars held together by gravity is called a galaxy. Galaxies can contain billions to trillions of stars, along with gas, dust, and dark matter. They come in various shapes, such as spiral, elliptical, and irregular. Our own Milky Way is an example of a spiral galaxy.
A group of billions of stars, along with dust and gas, that is bound together by gravity is called a galaxy. Galaxies come in various shapes and sizes, including spiral, elliptical, and irregular forms. The Milky Way is an example of a spiral galaxy containing our solar system.
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.
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.
Gravity - from the stars, dust, etc., but especially from "dark matter", a substance of yet unknown composition.
