well to tell how far they are its trick even by using the best telescopes we cant still tell but by its light reaching us there's a 50 chance of how far it is in addition we can tell how big it is also.
quintillions of miles away.
Maybe life on planets far far away!
For example, galaxies are very large, very massive, very bright, and (most of them) very far away from us.
The farther a galaxy, the faster it moves away from us.
That has nothing to do with the "type"; it is how far they are away from Earth. Due to the general expansion of the Universe, galaxies that are far way from us systematically move away from us - the farther away, the faster. It is only nearby galaxies which may happen to move towards us.
That is impossible to answer because scientist don't know ALL the galaxies.
Most galaxies have a red shift away from us - meaning they are moving away from us. However, the Andromeda galaxy has a blue shift, which means it is moving towards us. In about 2.5 billion years time, the two galaxies will merge.
It is not known and never will be known. Other galaxies are too far away for us to find if they have life in them. So far earth is the known only place in the universe to hold life.
I suppose you might say that the main reason is they're incredibly far away! We haven't even gotten to other planets yet, and you're wondering about galaxies? The nearest other galaxies are so far away it takes even light 150,000 years to get there!
Sorry, no galaxies can be found within the solar system.
One has to go to far-away galaxies to get hold antimatter particles
No. All the stars you see at night are in our galaxy. Stars in other galaxies are much too far away to be seen without a powerful telescope.
