"Sound propagates in gas, so the question begs... Does Uranus make noise ?"
Technically Earth should too, and does. Either way there needs to be a source of sound, here it happens when the air 'rubs' (or repeatedly bounces) against itself (different density or pressure) or another "phase of matter" object. In caverns on Earth, winds would go over it's openings and a sound can be heard like blowing air over a bottle. But Uranus is like Jupiter right, does it have a decernable surface, so to speak? What's there to 'rub' on other than itself? Perhaps the poles have airborne ice crystals, that has got to sound weird, like the sound sand dunes make when wind goes over them, like a deeply tuned harmonica or maybe even symbols in a drumset...basically the pure sound of millions upon zillions of moles of sand cubes falling on each other -- dammit Go4EVA, now you got me yearning for that sound!
Most weather phenomenon on Earth do not go anywhere near our poles, what can we expect on Uranus, unless it has some kind of plate techtonic motion dispite [my] verification of a surface... I do not know that if it does, someone tell me, is plate techtonics limited to Earth for whatever reason, or is it safe to assume it happens elsewhere?
I assume natural phenomenon exists wherever natural occurances exists, i.e. stuff God made.
I'd like to know more about Pluto, how can we tell on Earth if it is a planet or an asteroid and is there a difference other than some size issue? We've discoverd other planets bigger than Jupiter yet smaller and similar to our sun, are they then stars now?
Go4EVA, you're @NASA right, are you being told or can you find out what is going on in terms of infant (time wise) projects into space?
The meaning of life is curiosity; we were put on this planet to explore opportunities.
