Aware space has got cheered up (11)
I believe the answer is:
enlightened
'aware' is the definition.
(thesaurus)
'space has got cheered up' is the wordplay.
'space has' becomes 'en' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'got' means one lot of letters go next to another.
'cheered up' becomes 'lightened' (lightening is a kind of cheering up).
'en'+'lightened'='ENLIGHTENED'
Can you help me to learn more?
(Other definitions for enlightened that I've seen before include "Having spiritual insight" , "Rational, tolerant" .)
