You aren't getting what I mean. What I don't want is people making things up where there should be nothing for the purposes of the story. Don't add unnecessary complication where it's not needed. A narrative Occam Razor.

There are characters like the Celestial Spirits and Eldritch Beings that are certainly linked to space, but it's mostly in a metaphysical way. What I tried to say is that, unless you go really out of your way looking for Yog-Sothoth's bedroom, all that miyu would find there is the same thing that astronomers find when they look at the sky, huge balls of gas and dust floating away in an endless vacuum.
