By studying galaxies much farther away. The logic behind that is that since distances are so great in deep space and light can take billions of years to cross those distances, you can see what a galaxy looked like a billion years ago if it is located a billion light-years away. It is possible to get an idea of galaxy evolution because of that.
People also model galaxy evolution on super computers by throughing in real life parameters. While not real galaxies, if the model works then it's most probably because the parameters that have been programmed into the computer are correct and that scientists are onto something.

∙ 13y agoScientists find about different galaxies through many ways.
1) They use the Hubble Telescope to find distance cluster of stars or other objects in cpace
2)They use through Csomic Alignment, they use cosmic lenses in otherwords
3) They use ESPO'S Very Large Telescpoe

Do scientists know of any other galaxies in the universe besides the Milky Way?
Yes.
How do scientists study the movement of galaxies in the universe?
blah blah blah... I dont know...
Why do scientists study distant galaxies to learn about galaxies?
cuz they are explorers
Do scientists know everything about space and space travel?
No, they don't. There is so many (beyond numbers) galaxies that it is impossible to know everything.
Why is it important to view galaxies that are far away and galaxies that are close?
To know what is the life there, and if there's any other creatures or "aliens". some scientists are looking for planets with water and life on them.
Do scientist study other galaxies because they want to learn about the speed of light?
No. We already know a good deal about the speed of light. Scientists study other galxies to learn how galaxies work.
Why do they think there are hundreds of thousands of galaxies?
They (scientists) think there are hundreds of thousands of galaxies because the universe is limitless so there may be billions of galaxies!
What do scientists know about the size of the universe?
We know that we have observed galaxies out to as much as 14 billion light years from us in every direction, and we have never seen an end to it yet.
Why do scientists believe that there are billions of stars in galaxies?
Because they can see them.
Scientists believe that the more distant galaxies formed?
the answer is "first".
Are there at least 350 billion or more large galaxies in the observable universe?
Yes, because scientists have found hundreds and hundreds of galaxies already and scientists say that there are more galaxies out there that they haven't found!
Which objects helps scientists discover how galaxies and planets are formed?
penis
