Is outer space noisy?
Nope, it is 100% silent!
If you (for whatever, peculiar reason) decided to leave your space station with simply the clothes on your back, and had your bare ears exposed to space- you would be met with silence.
You might hear your ear drums pop, but other than that there is no audio because there is no medium (like air, water or ground) for it to travel through.
However, that doesn't necessarily mean space doesn't make noise. Objects like the Sun, Mars, our moon and even our Planet make noise in the form of radio waves and other methods. And believe me, the sound of the Sun is something pretty spooky.
