WOW, today I accidentally found out planets make sound! And even the Sun does. This is the Jupiter. Look out for the Pluto, it makes the most extraordinary sounds in my opinion. And the sounds of Uranus sound like military jet aircraft. The Earth sounds weird. The best is to listen during night, with all lights and other sounds turned off.

Jupiter sounds (so strange!) NASA-Voyager recording

Yep.  And that's only in the 20-kilohertz range.  There's still 180-kilohertz of leftover ultrasound that we can't hear. 

Proportionately, pulsating-star noise would drown everything out.  For Earth, the Crab-pulsar is like an obnoxious radio-boombox shattering the tranquility of the entire neighborhood.
