    Cassini-Huygens passing through Saturn's rings - Space Sounds
    Dec 12 2023
    NASA/ESA/ASI Cassini-Huygens spacecraft is hit by millions of dust particles as it goes through a gap in Saturn's icy rings.Although the ring gaps appear empty, they are not. The spacecraft ploughed through these dust particles at a speed of about 70 000 kilometres per hour! These impacts, converted into audible sounds, resemble hail hitting a tin roof.

  • Whistler Atmospheric squeaking - Space Sounds

    Whistler Atmospheric squeaking - Space Sounds
    Dec 12 2023
    Whistlers were first occasionally heard at the end of the 19th century on long-distance telephone lines. They are electromagnetic emissions produced in the atmosphere, but their cause is still partly unclear. They originate from thunderstorms or meteorites, or even after earthquakes. Once produced, the sounds travel along closed magnetic field lines from one hemisphere to the other. Studying them can yield information about the Earth's atmosphere, ionosphere, and magnetosphere up to very long distances. This one is a lightning strike recorded by Cluster (courtesy of Prof. D. Gurnett, University of Iowa).

    Dawn in Space - Space Sounds
    Dec 12 2023
    'Dawn chorus' signals detected by ESA Cluster’s WBD (Wide Band Data) instrument.High-energy electrons get trapped in the Earth’s radiation belts. When they are accelerated by the electromagnetic field, they produce this familiar sound. With the help of missions studying particles in space like the four Cluster spacecraft, ESA scientists are investigating how the electrons are accelerated and how the sound like the 'dawn chorus' of birds is created.

  • Auroral Star Wars - Space Sounds

    Auroral Star Wars - Space Sounds
    Dec 12 2023
    Sound of an Auroral Kilometric Radiation (AKR) collected by Cluster resembles the one of R2D2, the little robot from 'Star Wars'.Earth can generate radio emissions in a natural way. The most intense of these emissions is a phenomenon called Auroral Kilometric Radiation (AKR). It is produced in the auroral zones at an altitude between 3000 and 20 000 kilometres. Afterwards, the sounds escape outward in the space from the magnetic field lines. AKR intensifies during magnetic and auroral substorms so you can use it as a remote indicator of geomagnetic activity. The Wide Band (WBD) instrument on-board Cluster recorded this sound and made the first direct determination of the locations of an AKR

  • Wailing of Leonids - Space Sounds

    Wailing of Leonids - Space Sounds
    Dec 12 2023
    Each time a meteor crosses the atmosphere, it leaves behind a short trail of ionised particles. This trail reflects high-frequency radio signals from stations around the world for just a few seconds. The motion of the meteor trail due to the upper atmosphere winds changes the frequency of the reflected signal (Doppler effect). You 'hear' the trail as it is blown around by the winds before it is eventually dispersed.

    Carina Nebula Sonification
    Nov 27 2023
    This sonification does not represent sounds recorded in space. Two musicians mapped the telescope’s data to sound, carefully composing music to accurately represent details the team would like listeners to focus on. In a way, this sonification is like modern dance or an impressionist painting — it converts Webb’s image to a new medium to engage and inspire listeners.
