Yes they do.

Astronomers refer to a galaxy with a jumbled scattering of stars as an "irregular galaxy." These galaxies lack a defined shape or structure, distinguishing them from spiral or elliptical galaxies. Irregular galaxies often contain young stars, gas, and dust, and they can be the result of gravitational interactions or collisions with other galaxies.
they usually use super computers
With current technology, astronomers are able to detect objects (galaxies) out to about 14 billion light years from us in every direction. We don't know what's farther than that.
An astronomer studies celestial bodies, which include stars, planets, moons, comets, and galaxies.
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.
Galaxies. They are just about the same now as they were then. 14 Billion years ago, astronomers believe that the "Big Bang" created matter from energy, which is how they believe galaxies were formed.
astronomers did
Astronomers group galaxies into three types based on their characteristics: spiral galaxies have arms that spiral out from a central bulge, elliptical galaxies are oval-shaped with no distinct structure, and irregular galaxies have a chaotic and asymmetrical shape.
Perhaps in the future astronomers will do all the redshifts of the 100 billion galaxies in the universe.
That the galaxy is moving away from us.
There is no answer
It is possible that someday astronomers will measure all the distances of the 100 billion galaxies in the universe.
most of the mass in a cluster of galaxies is invisible, which provides astronomers with the strongest evidence that the universe contains a great amount of DARK MATTER

Billions. (rounded)
They were discovered by astronomers using telescopes.
It is possible that astronomers will measure all the sizes of 100 billion galaxies in the observable universe.
