They can merge, to combine into a single, larger, galaxy. Or, they can separate again.
------------
"Collide" is a misnomer because of the vast distances between stars in a galaxy, the odds of a stellar collision are extremely small.
The Andromeda Galaxy and the Milky Way Galaxy are on a collision course. If you're around when they begin to "collide" in about 4-Billion years, don't expect to see any fireworks in the sky. Except for an increase of the number of observable stars in the night sky, it will largely be a non-event.
What else can I help you with?
Can galaxies steal stars from one another?
Not generally, but galaxies do collide sometimes. In fact, the Andromeda Galaxy will probably collide with the Milky Way in about 3 billion years or so. In the collision, stars are often "flung" from one galaxy to the other, or thrown out of the original galaxy entirely. Follow the link below to see what happens when galaxies collide!
What will happen to the Milky Way and Andromeda galaxies 4 billion years from now?
Four billion years from now, our galaxy, the Milky Way, will collide with our large spiraled neighbor, Andromeda.
How many years until the Andromeda and Milky Way galaxies collide?
There are 2 much smaller irregular galaxies that orbit our galaxy called the Magellanic Clouds. These are abbreviated LMC and SMC (large and small Magellianic Cloud). These will one day gradually collide with The Milky Way but it is a long time until that happens; no need to worry. There is also the Andromeda Galaxy which is on a collision course with us.
How do computers help astronomers understand what happens when galaxies collide?
Computers help astronomers by running complex simulations that model the collision of galaxies, taking into account factors such as gravity, momentum, and gas interactions. These simulations provide a way to observe and analyze the various outcomes of galactic collisions without having to wait thousands or millions of years for them to happen naturally. By studying these simulated collisions, astronomers can gain insights into the processes involved and better understand the effects of such events on the galaxies involved.
When two plates collide what can happen?
When two oceanic plates collide, one may be pushed under the other and cause magma from the mantle to rise, forming a volcanoe or volcanoes. When two continential plates collide at a reverse fault tectonic earthquakes occur.
Do galaxies ever meet?
Yes. Galaxies do sometimes collide.
What happens when two spiral galaxies collide with each other?
You tend to end up with irregular galaxies

What is one way that an elliptical galaxy differs from the other types of galaxies?
Elliptical galaxies are large blob shaped galaxies that most galaxies will eventually look like. Elliptical galaxies are what happens when two or more large galaxies collide and coalesce.
What will happen to the Milky Way and Andromeda galaxies 4 billion years from now?
Four billion years from now, our galaxy, the Milky Way, will collide with our large spiraled neighbor, Andromeda.
When did Gradius Galaxies happen?
Gradius Galaxies happened in 2001.
What happens if 10 galaxies collide into each other at the same timeHow big would the supernova be?
When galaxies "collide", the individual stars do not actually smash together; they're far enough apart that they mostly slip past each other.
What happens when two galaxies collide?
Well ... they don't really collide - because a galaxy consists mostly of empty space. What does happen is that their gravitational fields overlap and the two merge into one. Possibly holding the shape of the dominant of the two, but also possibly forming a new shape altogether.
What is a merging galaxy?
Not "a" merging galaxy - merging galaxies. Sometimes two (or even more) galaxies collide, and eventually combine (i.e., "merge") into a single galaxy.
When will Andromeda Galaxy collide?
The Milky Way galaxy and the Andromeda galaxy are moving towards each other that a rate that will make them "collide" in about three and a quarter billion years. "Collide" is in quotes, because galaxies are mostly empty space, so it's fairly unlikely that any of the individual stars making up the two galaxies will physically touch as a result of the "collision"; instead, the two galaxies will just merge into a larger one.
When did Star Wars Galaxies happen?
Star Wars Galaxies happened in 2003.
Since the universe is thought to be expanding why do galaxies collide?
Because although the universe is expanding, the galaxies within it are grouped into clusters. These clusters are still under the influence of gravity, so slowly, over many years, they are attracted towards each other and can collide with one another.
