Most galaxies just fly around at varying speeds, but sometimes they collide, and when that happens, it means that all of the stars and planets within one galaxy clash with the others. The explosion and aftereffects that ensue, are, well, astronomic. Most of the planets and stars would crash into each other and become big balls of hot gas and magma, and some of them would combine, some of them would fly around and be shot into space due to the massive amounts of opposing gravity amassing. As for the cores of the galaxies, the Super Massive Black Holes, they would suck up anything that they could find, and eventually crash into each other. I actually don't know what would happen when Super Massive Black Holes collide, but I'm sure you can use your imagination for that. ;)
*Most of this stuff is theoretical, because us humans haven't been out there to see and experience it for ourselves.
To know that would be to know the meaning of life.
They are cool
who discovered the galaxies who discovered the galaxies
Spiral galaxies, barred spiral galaxies, elliptical galaxies, and irregular galaxies
Elliptical galaxies are sometime called dwarf galaxies.
15 Galaxies? There are over 1,000,000,000 galaxies possibly more.

The two main theories of galaxy formation are the bottom-up theory, where galaxies form from mergers of smaller structures like dwarf galaxies, and the top-down theory, where galaxies form from the gravitational collapse of large gas clouds. The hierarchical model is a popular framework that combines aspects of both theories to explain the variety of galaxy shapes and sizes observed in the universe.
no galaxies are not harmful
spiral galaxies (ours), irregular galaxies, and elliptical galaxies.
The possessive form for the plural noun galaxies is galaxies'.Example: Their galaxies' paths do not coordinate.
You can have dwarf elliptical 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.
there are a few kinds of galaxies in our universe.
