Woman right about celestial objects (7)
I believe the answer is:
stellar
'woman right about celestial objects' is the definition.
I can't judge whether this definition defines the answer.
'woman right' is the wordplay.
I cannot really see how this works, but
'woman' could be 'stella' and 'stella' is found within the answer.
'right' could be 'r' (common abbreviation) and 'r' is found in the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for stellar that I've seen before include "of celebrities" , "Star-like, with star quality" , "Starry" , "Exceptionally good" , "Top-notch" .)
