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 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.
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 vast group of stars is called a galaxy. Galaxies are large systems of stars, gas, dust, and dark matter, bound together by gravity. The Milky Way is an example of a galaxy that contains our solar system.
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 group of stars that form when a lot of gases and dust come together is called a star cluster. Star clusters can be either open clusters, which are loosely bound and contain young stars, or globular clusters, which are tightly bound and contain older stars.
A galaxy
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.

Is called a galaxy
Such groups exist at different levels:* Star clusters * Galaxies * Galaxy clusters * Superclusters

Gravity - from the stars, dust, etc., but especially from "dark matter", a substance of yet unknown composition.
A Nebula! :D!
