Asteroid captured by space researchers (5)
I believe the answer is:
ceres
'asteroid' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'captured by space researchers' is the wordplay.
'captured by' says the answer is hidden in the clue.
'CERES' is hidden in the letters of 'space researchers'.
Can you help me to learn more?
(Other definitions for ceres that I've seen before include "Roman goddess; dwarf planet" , "Head of agriculture" , "She fills granaries" , "The largest asteroid" , "Roman goddess of agriculture" .)
