Weather research centre that's out of this world (6)
I believe the answer is:
skylab
'weather research centre that's out of this world' is the definition.
(I've seen this before)
'weather research centre' is the wordplay.
'weather' becomes 'sky' (I've seen this before).
'research centre' becomes 'lab' (I can't justify this - if you can you should give a lot more credence to this answer).
'sky'+'lab'='SKYLAB'
Can you help me to learn more?
(Other definitions for skylab that I've seen before include "US space station launched in 1973" , "1973-79 space station" , "research unit once in orbit" , "Weather research centre that's out of this world" , "1970s' space station" .)
