These helped predict the existence of dark matter. Dark matter in astronomy is used appear as the result of mass, where no actual mass can be seen.

Do astronomers know how galaxies are formed?
Yes they do. See related question.
Do Astronomers use microwaves to learn about the structures of galaxies?
they usually use super computers
How do computers help astronomers understand what happens when galaxies collide?
By translating the math model of a galaxies and a galaxy collisions into a simulation. And theoritically observe the process by experimenting with the variables.
What is the name of a sicentist that studies celestial bodys?
An astronomer is a scientist who studies celestial bodies (planets, stars, black holes, moons, nebulae, galaxies).
The scientist who proved the existence of galaxies other than the Milky Way was who?
Mister Edwin Hubble did just that, before the 1920's, many astronomers thought that our galaxy included everyobject in space, in 1924 Edwin Hubble proved that other galaxies existed beyond the milky way
Who thought of galaxies?
astronomers did
Will astronomers do all the redshifts of the 100 billion galaxies in the universe?
Perhaps in the future astronomers will do all the redshifts of the 100 billion galaxies in the universe.
If light from galaxies is redshifted what can astronomers conclude about galaxies?
That the galaxy is moving away from us.
Will astronomers measure all the distances of the 100 billion galaxies in the universe?
It is possible that someday astronomers will measure all the distances of the 100 billion galaxies in the universe.
Why do astronomers theorize that most of the matter in galaxies and clusters of galaxies is dark matter?
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

How many galaxies do astronomers believe there are?
Billions. (rounded)
How galaxies discovered?
They were discovered by astronomers using telescopes.
Will astronomers name all the designations of the 100 billion galaxies in the universe?
It highly likely that astronomers will name all the designations of the 100 billion galaxies in the universe in this lifetime.
Will astronomers get all the J2000 coordinates of the 100 billion galaxies in the universe?
Maybe someday in the future astronomers will get all the J2000 coordinates of the 100 billion galaxies in the universe.
Will astronomers measure all the sizes of 100 billion galaxies in the observable universe?
It is possible that astronomers will measure all the sizes of 100 billion galaxies in the observable universe.
How can astronomers get all the morphological types of 100 billion galaxies in the universe?
Astronomers can get all the morphological types of 100 billion galaxies in the universe by help of the merger rate.
