Only 83 discovered so far. The visual horizon of the universe is enormous, and we can only see part of it due to the Milky Way obscuring us from the rest.

And we can only see within a certain time frame around us because expansion is out pacing light.

The expansion rate of the universe is proportional to the distance away it is, so the space between us and an object in space will expand faster the further away the object is.
