Yeah I agree it is most probably radio waves - sound can't travel in a vacuum.Natural radio waves I can maybe understand but the hum sound, well sound doesn't exist in space :/ So I am a little conffuzzed!?

Oh, and who decided that the sounds are "cries"? To me it sounds like static you pick up when tuning on the AM frequency.
Space isn't a vacuum...

I am sure it will vacuum your eyeballs through your nose should your space helmet break![]()
That would suck![]()
For all practical reasons, space is a vacuum. It is impossible for sound to travel in space. Radio waves and other waves simply sounds exactly the way we want to interpret them![]()
what is it then? the final frontier?Wrong. Space is not a vacuum.

Outer space is the closest physical approximation of a perfect vacuum. It has effectively no friction, allowing stars, planets and moons to move freely along ideal gravitational trajectories. But no vacuum is truly perfect, not even in intergalactic space where there are still a few hydrogen atoms per cubic centimeter.
