A thread I've seen elsewhere was about appropriate music for our celestial voyages.
One selection that always pops into my head when I set sight on the Trapezium amid the Orion Nebula is Into The Mystic by Van Morrison:

We were born before the wind
Also younger than the sun
Ere the bonnie boat was won
As we sailed into the mystic

Hark, now hear the sailors cry
Smell the sea and feel the sky
Let your soul and spirit fly
Into the mystic

If there's a top ten for stargazing tunes that would have to rank right up there.
