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.
That is not certain. The first galaxies might have formed as gas from which stars condensed. The stars may have formed first, and later gathered together as galaxies. It could be different in different galaxies. Stars continue to form in galaxies but it is still difficult to know which came first.
Yes, stars are third cousins to most modern day galaxies.
Galaxies are formed from stars
They did not emerge fully formed.
Bigger galaxies. And stars.
Galaxies are the massive collection of stars. Therefore galaxies could not have formed without stars.
It depends on how much gravity that causes stars to form. It depends on how big the star in the galaxies is.

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.

Stars, Planets, nebulae, galaxies.
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.
All stars and galaxies are in the universe.
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.
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
