While I agree most of the scatting is happening in our atmosphere, and that space is mostly nothing, it’s not completely nothing and when there is something there tends to be a massive amount of something there. There is a lot of dust, and there is a lot of space between us any any of there light source there is out there. And anything that we are interested is where a bunch of stuff is. This is why we want to look at the IR spectrum instead of the UV spectrum because IR light scatters much less in the presence of dust, and the UV spectrum of light can be scattered or blocked a lot easier.
