The vast distances involved means that the light we see left those galaxies a long time ago.
We measure the movement of stars to study their motion within galaxies, determine their distances from Earth, and investigate their spectral shifts to learn about their composition and temperature. Studying the movement of stars also helps scientists understand the dynamics of galaxies and the evolution of the universe.
Mainly that galaxies that are very far away (i.e., from the distant past) look different to galaxies that are near-by (from the more recent past).
Galaxies are organized into clusters and superclusters. Clusters contain many galaxies that are bound together by gravity, while superclusters are even larger structures made up of multiple galaxy clusters. These structures are interconnected by filaments of gas and dark matter, creating a vast cosmic web-like structure in the universe.
Look in the discussion for the answers and choose one!
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.
Those two things are completely unrelated.The Universe looks the same in different directions.The Universe does NOT look the same at different distances. If you look at farther galaxies, in other words farther back in time, they look different than galaxies look now. If you look even further in time, at one time there weren't even any galaxies.Those two things are completely unrelated.The Universe looks the same in different directions.The Universe does NOT look the same at different distances.

Galaxies get bigger by a process of merging. The gravitational attraction of the galaxy and the dark matter round it pull in satellite galaxies and these merge with the main galaxy. Eventually large galaxies merge to form large elliptical galaxies. look at the link below.
Yes. Some examples of galaxies (which you can look up) are the: Andromeda Galaxy, the Large Magellanic cloud and the Small Magellanic Cloud.
No stars are actually a galaxy. All stars are stars and all galaxies are galaxies. Stars are found in galaxies. Some galaxies look like tiny dots in our night sky, so might look like a star, but they are not stars; they are galaxies.
No.
The large magellanic cloud galaxy has an irregular shape. It does not look like spiral and elliptical galaxies shown in pictures.

Galaxies change very slowly.
no the image is distorted
