'a feature of jupiter' is the definition.
I don't know anything about this answer so I can't judge whether this works.

'3-d arrangement to see' is the wordplay.
'e d arrangement' becomes 'thered' (I can't explain this - if you can you should believe this answer much more).
'to see' becomes 'spot' (to spot is to notice or catch sight of).
'thered'+'spot'='THE RED SPOT'
