NASA's Cassini captures disturbing sounds during its Saturn mission

I If you need some white noise and want to feel stuck in a haunted wind tunnel, NASA covers you. In 2017, the agency abandoned the mixtape "Spooky Sounds of Across the Solar System", which includes the titles "Plasmaspheric Hiss" and "Jupiter Sounds 2001". Now, NASA returns with sounds gathered during Cassini's mission to Saturn. The disturbing noises, representing the interaction of plasma waves moving between the gaseous giant and its moon Enceladus, sound strangely like the Upside-Down in Stranger Things .

In his last days, his Radio Plasma Wave Science instrument has detected pulsed plasma electromagnetic waves in a range of audio frequencies and recorded them. Although plasma waves often occur naturally at audio frequencies, a human in space could not hear them because the pressure is too low.

On Earth, researchers were able to amplify and compress these signals, transforming them into

This record led to the discovery that plasma waves travel from Saturn to its Enceladus rings and moon along connected magnetic field lines. This process, says NASA, is no different than an electrical circuit moving between two bodies. Unlike the Earth's Moon, Enceladus is immersed in the magnetic field of Saturn and is a geologically active hotspot that spits ice particles and vapor plumes, which inevitably become part of the largest ring of Saturn

and we know that it's a source of continuous energy, "said NASA scientist and planet scientist Ali Sulaiman, Ph.D. Now we find that Saturn responds by throwing signals in the form of plasma waves, through the circuit of magnetic field lines connect it to Enceladus to hundreds of thousands of kilometers. "

Enceladus is a competitor for one of the places where we are most likely to encounter life in the space. During his mission, Cassini dived within 15 miles of the moon's surface – a dive that revealed the moon's global underground ocean. This ocean seems to be similar to Earth's deep hydrothermal vents, which means it could contain life-friendly conditions – even though this life is tiny chemosynthetic microbes. However, it is unlikely that they send us audio recordings, so if you want to know what Saturn looks like, you'll have to settle for that for a moment.
