Reference library for speculative exotic biochemistry and planetology
This thread will serve as a library of published scientific papers and well-thought-out worldbuilding resources that are highly relevant to the topic of speculative biochemistry and planetary science, especially regarding exotic environments very unlike Earth.

I and others will add papers below, and as I get a chance I will edit them into this first post.
