NASA Space sounds
What’s going on? Well, spacecrafts do a fly by and they record radio emissions from planets, or, planetary environments if you will. Afterwards, they change it to sound.
The actual sound itself? Well, it’s from electromagnetic particles colliding with each other. Where do they come from? Well, from the planet’s magnetosphere, Ionosphere and solar wind.
They sound really amazing! Nothing was later added. They come from mysterious worlds and beyond!
Take a listen!
