The spiral galaxy's.
Gases and stars and a massive central black hole.
A dwarf galaxy [See Link] is a small galaxy composed of up to several billion stars, a small number compared to our own Milky Way's 200-400 billion stars
No. The big dipper is just a small collection of a handful of stars. All stars that you see in the sky are part of the Milky Way Galaxy, which is composed of hudreds of billions of stars.
If you mean, what are they composed of, galaxies consist of stars, dust, gas, and black holes - but MAINLY they are made out of invisible stuff (dark matter), which makes up about 80-90% of a typical galaxy's mass.
A galaxy is by a definition a group of stars. If there were no stars it could not be a galaxy.
Every galaxy contains stars, if that's what you mean. "Galaxy" means "big bunch of stars". No stars ===> no galaxy.
Elliptical Galaxy The Elliptical Galaxy has mostly old stars and blue stars are new stars.
The Andromeda galaxy, also known as M31, is primarily composed of stars, gas, and dust. The stars in Andromeda are mainly older, with some younger stars found in its spiral arms. The gas in the galaxy consists of hydrogen and helium, along with trace amounts of other elements. The dust in Andromeda is made up of tiny solid particles, which play a crucial role in the formation of new stars.
A globular cluster (without "galaxy") is a large group of stars, in form of a sphere, within a galaxy. A galaxy may have thousands of such clusters. I am not sure whether the term "globular cluster galaxy" has any meaning in astronomy. It might be a galaxy with a lot of such clusters.
If it didn't have stars it wouldn't be a galaxy
