One of those looking up woman who knows where to find all the stars (10)
I believe the answer is:
astronomer
'woman who knows where to find all the stars' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe there's an association between them I don't understand?
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for astronomer that I've seen before include "Sky-at-night observer" , "Stargazer" , "Observer of space" , "One studying the universe" , "Moon starer (anag.)" .)
