Question on where to find books about space, blackholes and the like

Hey all. Apologies if this isnt the ideal place to be asking, am pretty new and couldn't find a space community. I'm a reddit refugee, and such have found extra time on my hands and am looking to delve into non-fiction space literature. Does anyone know a good community to ask this question? Or have any books they'd recommend?

Cheers, really have been enjoying lemmy!
