That sounds like a galaxy. It could also be a galaxy cluster or a supercluster.
A system of billions of stars held together by gravity is called a galaxy. The one we live in is called the Milky Way galaxy.
An island comprising billions of stars and nebulae, held together by gravity.
Billions of stars make up galaxies. Galaxies are vast systems of stars, planets, gas, and dust that are held together by gravity. Our Milky Way galaxy, for example, consists of billions of stars including our Sun.
The Milky Way is a barred spiral galaxy that contains billions of stars, dust, and gas. It is held together by gravity and has a central bulge surrounded by a disk. Our solar system resides in one of the spiral arms of the Milky Way.
Actually, a supercluster can contain millions to billions of stars, along with gas, dust, and dark matter. Superclusters are some of the largest known structures in the universe, made up of numerous galaxies and galaxy clusters bound together by gravity. They can span hundreds of millions of light-years.
Not quite, Millions of computers linked together are collectively known as the World Wide Web. The World Wide Web is a service that uses the internet
A galactic cluster is a collection of hundreds or even thousands of galaxies which are bound together by their gravity, each one containing billions of stars. The mass of a galactic cluster could be a quadrillion times the mass of the sun.
