These are wonderful! I was going to collect space as a theme but discovered most space theme are of astronauts, spacecraft and satellites, and other man-made features. Is there a topical list anywhere with just the cool stuff (planets, nebula, stars, etc)?

I found one on the topical stamp group's page but it was several thousand stamps amd included astronauts amd spaceships, I think. Tthere is one also on the APS site but it cuts out 10 or 15 years ago.

Put another way, is this thread the closest thing to a list there is? Thanks to anyone who might have a great answer, an educated guess, or just willing to look past the vastness of this request...
