First I want to thank you for this excellent picture.
Regarding your question I have no idea, but my feeling is that soon-ish an “earthporn” community will arrive at the Fediverse (if not have already). I miss those pictures, too.
EDIT: should have looked before posting. Of course an !earthporn@lemmy.ml exists in meantime, have subscribed immediately :)
The German Feddit was down for quite a while, but if this counts for 200 servers I do not know.
