Big stars dare Sting to get a makeover (3,6)
I believe the answer is:
red giants
'big stars' is the definition.
'red giants' can be an answer for 'stars' (type of star). I am not certain of the 'big' bit.
'dare sting to get a makeover' is the wordplay.
'dare' becomes 'red' (I can't explain this - if you can you should believe this answer much more).
'to get' says to put letters next to each other.
'makeover' indicates an anagram (I've seen this in other clues).
'sting'+'a'='stinga'
'stinga' with letters rearranged gives 'giants'.
'red'+'giants'='RED GIANTS'
Can you help me to learn more?
(Other definitions for red giants that I've seen before include "Very large stars" , "Stars of high luminosity" .)
