acoustics - Can you record sound through vacuum? Like this: (object)(vacuum)(object)


There are these videos on youtube that play sound of Jupiter for example:

Does anyone know if this is real at all? How can you record sound through vacuum space that separates Earth and Jupiter?


I'll generalize my question: is it possible to record sound through vacuum? Let's say you're on Earth with atmosphere and pressure, there is vacuum around it, and then there is a planet with atmosphere again. Is it possible to record sound on planet at all while being on Earth? Sound waves dont reach earth so is there an indirect method to doing that?
