quintillions of miles away.
The space in between galaxies is far larger than the galaxies themselves.
There are more and more galaxies for as far as we can see.
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.
There are far too many to count or name
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.
That is impossible to answer because scientist don't know ALL the galaxies.
No. Some galaxies that old are visible.
Astronomers can watch galaxies that are far away. Since the light takes billions of years to reach us from the farthest known galaxies, they would be watching galaxies in the early Universe. It turns out, from such observations, that the Universe is changing.
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.
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!
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.
