Reply to comment by Adrewmc in If objects in space are far away, does light get scattered enough that it would look “low resolution” by the time it reaches us? by hau2mk7pkmxmh3u

If I recall correctly, this is why most of what we've seen beyond our galaxy is to galactic "north" or "south". If we aim our telescopes along the galactic plane, there's a ton of dust in the way (the "milky way" you can see with your eyes when in a dark enough location) that makes it hard to see anything past that.

I believe that limitation is for visible spectrum telescopes. IR telescopes can see through the dust because IR is not impacted as much.
