ELI5- If sound can't travel through a vacuum, how is it we have recordings of the sound of space such as the Sun, and Jupiter?

Its not actually sound. They take readings of radiation that comes off of the object or they take readings of its magnetic field. They then use these electromagnetic radiation readings to create a sound wave. The intensity of the reading corresponds to the volume of the sound and they normalize the frequency of the EM wave so that it falls within the range of human hearing.
