Some galaxies are bound together gravitationally into what is called Local Groups.
Because of the gravitational attraction between them they are approaching each other.

When a number of cluster of galaxies join together they form a of galaxies?
That's called a supercluster.
Why are our galaxies separated?
For starters, if there were no separation between two (or more) galaxies, it would be considered a single galaxies, not two or more. The reason matter is clumped together into galaxies at all (with separations in between) is because of gravity - gravity tends to do that, i.e., to clump things together.
What is a galaxy in physics?
A large band of stars, gas, and dust particles hele together by gravitational force is called galaxy. Galaxies are really complex in nature consisting of billinns of stars. Some galaxies emit a comparatively small amount of radio radiations compared to the total radiations emitted and r called nosmal galaxies. Some galaxies are found to emit millions of times more radio waves compared to normal galaxies. They are called radio galaxies.
Why do scientist study the light coming from distant galaxies?
They study distant galaxies because they want to know whats out in other galaxies and how many planets it has
Can two galaxies combine together?
Galaxies do combine or merge together. In about 4.5 -> 5.5 billion years time time, the Andromeda Galaxy will combine with our galaxy, the Milky Way Galaxy. In a lot of cases Irregular Galaxies are believed to have formed with interactions with other galaxies. See related link for a picture of two galaxies merging.
Are some irregular galaxies nearly 13 billion light-years from earth?
Yes, they are usually of a similar size range to other types of galaxies, from a few thousand lightyears across to a million or more. Their formation is often as a result of two or more galaxies colliding, or coming close to each other.
What is all of the galaxies put together called?
The Universe
What holds the galaxies and solar systems together?
Galaxies are held together by gravity. So are Solar Systems. In the case of galaxies, and galaxy clusters, it isn't entirely clear what type of masses provide this gravity - the amount of known matter is simply too small, by a factor of 5-10. For more information, do some reading on "dark matter".
What hold the local group together?
Gravity holds the local group of galaxies together.
What are galaxies that travel together through space called?
Clusters
What holds stars together to form shapes of galaxies?
GRAVITY!
What is the name of all the galaxies together?
its not the universe it's called a cluster.
