This audio comes from radio emissions that were discovered by radio wave detectors on board the Cassini spacecraft as it passed over Saturns rings in 2004.
The Cassini spacecraft was a spacecraft that was launched in 1997 by NASA, in collaboration with the European Space Agency (ESA) and the Italian Space Agency (ASI), to study Saturn and its moons. It was named after the Italian astronomer Giovanni Domenico Cassini, who discovered four of Saturn’s moons and the gap in Saturn’s rings known as the Cassini Division.
The Cassini spacecraft made many scientific discoveries during its mission, including the detection of a subsurface ocean on the moon Enceladus and the discovery of hydrothermal vents on the moon Titan. One of the most interesting phenomena that Cassini observed was a mysterious sound that it recorded near Saturn.
The sound was described as a “whooshing” noise that was picked up by the spacecraft’s radio and plasma wave science instrument. It was heard repeatedly over a period of several months in 2002 and 2003, and it seemed to be coming from the area around the planet’s rings. Despite the many theories that have been proposed, the exact cause of the mysterious sound remains unknown.
It claims that NASA’s note on the file stated: “A most intriguing file, we do not know what to make of it.”
Some have theorised the sound when digitally enhanced reveals communication from an alien lifeform and possibly musical notes.
It sounds a lot like an alien spacecraft, doesn’t it? Scientists cannot explain the source of this signal. In fact, NASA’s official response to this file is, “A most intriguing file, we don’t know what to make of it.”
There is a lot of info on this Cassini recording if you care to investigate. Did Nasa record the sounds of extraterrestrial life? Judge for yourself on video.
