because . they want to look at a star one moment then go back and see if it moved or if the star is in the same place . that's mainly what the are searching for.
to learn more about our galaxy.
They study distant galaxies because they want to know whats out in other galaxies and how many planets it has
Scientists study distant galaxies to understand the formation, evolution, and properties of galaxies over time. By observing galaxies that are far away, they can explore the universe at different epochs and gain insights into how galaxies have changed and evolved since the early universe. Studying distant galaxies also helps scientists refine theories about the laws of physics and the nature of the universe as a whole.
That is impossible to answer because scientist don't know ALL the galaxies.
The visible part of distant galaxies is the collection of stars, gas, and dust within the galaxy. These components emit light that reaches our telescopes, allowing us to observe and study the structure and properties of the galaxies.
The "nucleus".
No. We already know a good deal about the speed of light. Scientists study other galxies to learn how galaxies work.
Because the universe as a whole is expanding, distant galaxies are moving away from us. As a result, electromagnetic waves emitted by those galaxies experience what is known as a red shift. Their wavelengths get longer.
Scientists believe that galaxies formed earlier in the universe's history, with the most distant galaxies being some of the first to have formed after the Big Bang. Studying these distant galaxies can provide insights into the early stages of galaxy formation and evolution.
If you look at a distant galaxy, the light from the galaxy has travelled for perhaps a hundred million years, a billion years, or up to an age close to the age of the Universe (13 billion years or so), depending on the galaxy's distance. Thus, the light you see shows you how the Universe was billions of years ago.
This should be because of the fact that the Universe is expanding. You see a blueshift when objects move closer to you. Other than super distant galaxies, most galaxies will not measure to be a blueshift due to the fact that the Universe is expanding and accelerating.

Far or near, all galaxies were thought to be formed in the first half billion years of the formation of the universe ... that is, about 13 billion years ago. Note that we're seeing the distant ones in a younger stage of development.
