The premise is that if the outer space, the space outside our planet Earth, and beyond the limitless Universe is almost a vacuum, then there would not be any sound.
So that space explorers will hear nothing, except the eerie, deafening sound of ….. silence. Totally.
And following the same line of thought, Earth’s space explorers will come home empty handed even with the aid of a high tech recording gadget available now.
Except, perhaps of a long kept secretive detail by NASA of US astronauts during a manned flight to the moon hearing outer space type music.
But then again, after many many man made crafts dispatched, some came home with, or sent back eerie space sounds.
First, we have the the eerie sounds from Saturn.
NASA’s Cassini spacecraft has been detecting intense radio emissions from the planet Saturn. They come from the planet’s aurorae, where magnetic field lines thread the polar regions. These signals have been shifted into the range of human hearing and compressed in time.
As space probe Voyager 2 passes the Uranus system on Janurary 24, 1986, specifically the planet’s moon Miranda, it came up with sounds recorded vividly.
(We are made aware that electromagnetic phenomenons can be converted into electric signals which in turn amplified to excite the membrane of a loud speaker making distinctly audible to human ear.)
Eight solar planet, and the fourth largest, Neptune plays this space sound:
Our own Earth, too, was recorded with the eerie sound below:
