Galaxies are vast collections of stars. So I guess you could say that a big group of stars forms a galaxy. Our galaxy has many big clusters of stars within it, so not all star clusters are galaxies. If you have a cluster of several million or billion (or trillion) stars surrounded by a lot of empty space, that is probably a galaxy.
What else can I help you with?
When galaxies collided they form?
Bigger galaxies. And stars.
Which objects began to form in your universe earlier stars or galaxies?
Galaxies are the massive collection of stars. Therefore galaxies could not have formed without stars.
Describe how gravity causes stars to form galaxies?
It depends on how much gravity that causes stars to form. It depends on how big the star in the galaxies is.
What is a grouping of billion of stars that form a system?
Galaxies.
What is the grouping of billions stars that form a system?
Galaxies.
What holds stars together to form shapes of galaxies?
GRAVITY!
Which heavently bodies form the universe?
Stars, Planets, nebulae, galaxies.
What determines the shape of a galaxy?
That is related to their past history. Many galaxies have undergone collisions with other galaxies; this takes out most of the interstellar gas, and the galaxies can no longer form new stars. If I remember correctly, such galaxies will change into elliptical galaxies.That is related to their past history.

Which stars are actually a galaxy?
No stars are actually a galaxy. All stars are stars and all galaxies are galaxies. Stars are found in galaxies. Some galaxies look like tiny dots in our night sky, so might look like a star, but they are not stars; they are galaxies.
What are all stars and galaxies in?
All stars and galaxies are in the universe.
Where are galaxies?
Galaxies were made by God from the beginning of time.Answer:The scientific opinion is that galaxies result from the gravitational attraction of matter into stars and the interactions of the stars to form clusters of swirling stars.. The matter originated in the "Big Bang" that was the beginning of the Universe some 15 billion years ago.
How constellations different from galaxies?
Constellations are stars put together, usually to form a ancient figure in the stars, a galaxy is much different, They have planets and in galaxies you can find constellations. Big difference
