The recordings and sample sounds of the planets, moons and rings of planets in our Solar System
When we look at images or videos or think of outer space scenery most of us imagine and sense of feeling of total void, darkness, and most of all, silence. But is this really the case?
Although space is a virtual vacuum, this does not mean there is no sound in space. Sound does exist as electromagnetic vibrations.
In the same way, as sound wave resonates inside an organ pipe to create a musical tone, sound waves on a far vaster scale can resonate inside a star. By measuring the frequencies of these waves, astronomers can learn about the star´s internal structure.
Vibrations are generated by turbulence on the star´s surface.
The vibrations penetrate deep into the star´s interior, setting up resonant oscillations at frequencies depending on the star´s size density, and rotation.
Astronomers see the oscillations as subtle, rhythmic, rhythmic changes in the star´s brightness.
Resonant frequencies can vary from one every few minutes in Sun-like stars to one every few hundred days in red giants.
But what about the planets in our solar system?
Through specially designed instruments, the NASA Voyager, INJUN 1, ISEE 1, and HAWKEYE space probes used Plasma Wave antenna to record the vibrations all within the range of human hearing (20-20,000 Hz).
The recorded sounds are the complex interaccions of charged electromagnetic particles from the Solar Wind, ionosphere, and planetary magnetosphere.
The recordings include:
Rins of Uranus
Song of Earth
Sphere of IO
& Voice of Earth
Below is the video with samples of the original recordings from Nasa Space Sounds YouTube Channel
