When galaxies collide, the following events can happen:
1. They can merge: When two galaxies collide, they can combine and form a larger, new galaxy. This can result in the formation of a larger and more massive galaxy.
2. They can interact: Even if galaxies do not fully merge, their gravitational interactions can cause distortions in their shapes, trigger the formation of new stars, and induce the ejection of gas and dust from the galaxies involved.
3. They can trigger star formation: Galaxy collisions can cause an increase in the rate of star formation due to the compression of gas and dust during the gravitational interaction. This can lead to the formation of new stars and the subsequent growth of galaxies.
4. They can exchange or steal stars: During a collision, gravitational interactions can cause stars to be exchanged between the colliding galaxies or get pulled out into long tails or streams of stars, known as tidal tails.
It is important to note that galaxies rarely completely disappear or destroy all their stars during collisions. Instead, they undergo various dynamic processes that can result in morphological changes and redistribution of stellar material within the merged or interacting galaxies.

The Andromeda Galaxy is predicted to collide with the Milky Way in several billion years. The collision between the two galaxies is expected to result in the formation of a larger galaxy known as "Milkdromeda" or "Milkedromeda." This event is part of the ongoing gravitational interaction between galaxies within the Local Group, which includes the Milky Way, Andromeda, and several other smaller galaxies.
