Large star in danger, it exploding (3,5)
I believe the answer is:
red giant
'large star' is the definition.
'red giant' can be an answer for 'star' (I've seen this before). I am not certain of the 'large' bit.
'danger it exploding' is the wordplay.
'exploding' indicates anagramming the letters.
'danger'+'it'='dangerit'
'dangerit' anagrammed gives 'RED GIANT'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for red giant that I've seen before include "Type of star" , "Large star nearing the end of its life" , "Large low-temperature star" , "Cool, immense star of high luminosity" , "big star" .)
