Things go pretty far in the universe. There's more then one galaxy. There's trillions for all we know, but all I can say is check the NASA website. They should have some info on there.
This question is about measuring distances in astronomy.
It has been a big challenge for generations of astronomers.
There are several methods. Each method works best for particular distances.
So, there's a series of overlapping distance scales:
"Radar" can sometimes be used for objects within our solar system.
"Parallax" can be used within the solar system and for fairly close stars.
"Cepheid variables" are useful for greater distances.
There are several other methods too.
Often the idea is to use objects with known "absolute luminosity" as "standard candles".
The brighter such an objectappears to be, the closer it must be.
There are particular methods used for very large distances. For example, a particular type of "supernova" is useful.
Finally there's the famous "redshift", which is greater at greater distance.
See "Sources and related links" (below) for more details.

What impact did the first space shuttle have on the world..... as in did it make society to day different?
The space shuttle helped us to be able to go into space and find out lots of info. we did not know. Before we had the space shuttle all we had were telescopes. Telescopes were good but all that they gave us were a picture and then we had to estimate how far away things in the universe were from other things were in the universe. Now that we have the space shuttle we are able to see things that we may not have seen with the telescope. We are also able to see how far away things are from other things
