I believe the answer is:

trophy

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

'awarded prize in astro-physics' is the definition.
I can't judge whether this defines the answer.

'in astro-physics' is the wordplay.
'in' indicates a hidden word.
'TROPHY' can be found hidden inside 'astro physics'.

Can you help me to learn more?

(Other definitions for trophy that I've seen before include "Scalp - memento" , "Cup, say, awarded as a prize for victory or success" , "Award for victory" , "Victor's prize" , "Kind of wife" .)

I've seen this clue in the Sydney Morning Herald.
