This video presents five mysterious "sounds" from space, three of which certainly originated in our solar system. All of these sounds are radio waves or plasma waves translated into sound for people to hear.
In the beginning, you can hear the sounds that NASA's Cassini spacecraft recorded as radio bursts from the poles of Saturn in April 2002. The fluctuations in frequency and time correspond to the activity of Saturn's auroras, much like our own radio bursts from the aurora and aurora borealis. Scientists believe that this complex band of rising and falling tones came from a variety of radio spots that moved along Saturn's magnetic field near the polar regions.
The second episode provides an opportunity to hear Voyager 1's entrance into interstellar space (excluding the Oort cloud) in 2012. This device is considered our most distant wanderer outside the Earth. It took him 35 years to hear the sound of this dense plasma (ionized gas) vibrating as it collided with the blast wave of the Sun's eruptions.
The third fragment is the "xylophone music" of comet 67P / Churyumov - Gerasimenko, recorded by the Rosetta spacecraft in August 2014. Scientists believe that this music is born in the process of "vibrations in the magnetic field of the comet's environment." To make this music audible to the human ear, the frequencies were amplified by about 10,000 times. But even now it remains a mystery exactly how these vibrations work.
Then the whistling sound (electromagnetic "whistling" radiation) of Jupiter's lightning recorded by Voyager is heard. When the radiated waves hit the plasma above the planet, the high frequencies travel faster than the low ones along Jupiter's magnetic field.
Finally, the "heartbeat" of the eating black hole in the GRS 1915 + 105 binary star system is heard, recorded by NASA's Rossi X-ray Timing Explorer in 1996 and converted to sound by scientists at MIT. NASA also recorded the heartbeat of a black hole in the IGR J17091-3624 system in 2003.
