Yawning, finding room that's beyond our atmosphere (4,5)

Ross

I believe the answer is:

deep space

I'm a little stuck... Click here to teach me more about this clue!

'beyond our atmosphere' is the definition.
I can't judge whether this definition defines the answer.

'yawning finding room' is the wordplay.
'yawning' becomes 'deep' (I've seen this in another clue).
'finding' is a charade indicator (letters next to each other).
'room' becomes 'space' (I've seen this before).
'deep'+'space'='DEEP SPACE'

'that's' is the link.

Can you help me to learn more?

(Other definitions for deep space that I've seen before include "void" , "Region beyond our atmosphere" , "even devoid of 12 [THIN AIR]" .)
