I'm a little stuck... Click here to teach me more about this clue!

'science prize thus bagged by idiot' is the definition.
I can't judge whether this defines the answer.

'science prize thus bagged by idiot' is the wordplay.
'science prize' becomes 'trophy' (I am not sure about this - if you are sure you should believe this answer much more).
'thus' becomes 'sic' (synonyms).
'bagged by' is an insertion indicator.
'idiot' becomes 'ass' (I've seen this before).
'trophy'+'sic'='trophysic'
'trophysic' going inside 'ass' is 'ASTROPHYSICS'.

Can you help me to learn more?

(Other definitions for astrophysics that I've seen before include "Branch of science" , "Science of stars and galaxies" , "Science of the properties of celestial bodies" .)
