Middle of mural has retro-looking star and another celestial body (6)
I believe the answer is:
uranus
'celestial body' is the definition.
(Uranus is an example)
'middle of mural has retro-looking star' is the wordplay.
'middle of' indicates the central letters.
'has' is a charade indicator (letters next to each other).
'retro' says the letters should be written in reverse (retro is Latin for 'backwards').
'looking star' becomes 'sun' (the Sun is a star. I am not sure about the 'looking' bit.).
The middle letters of 'mural' are 'ura'.
'sun' reversed gives 'nus'.
'ura'+'nus'='URANUS'
'and another' is the link.
Can you help me to learn more?
(Other definitions for uranus that I've seen before include "heavenly body" , "Seventh rock from the sun?" , "Most ancient of Greek gods, and a major planet" , "world" , "Uses profane language" .)
