Catastrophe making stars die out (8)
I believe the answer is:
disaster
'catastrophe' is the definition.
(I know that catastrophe can be written as disaster)
'stars die out' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'stars'+'die'='starsdie'
'starsdie' is an anagram of 'DISASTER'.
'making' is the link.
(Other definitions for disaster that I've seen before include "not a success!" , "Sudden catastrophe" , "Extreme event resulting in great loss and misfortune" , "complete failure" , "Calamity, tragedy" .)
