‘Sounds of Space’

Using a Very Low Frequency receiver at Halley Research Station we can pick up radio waves made by our planet. We use these waves to investigate the science of space weather storms, to help understand potential  space weather impacts on the climate system, and for lightning detection. We can also directly convert them into audible sounds and are exploiting these amazing natural ‘sounds of space’ in a number of collaborations. Scroll down to listen to the eerie noises of physics and find out more about the collaborations.

Our planet naturally produces a variety of radio emissions. These radio waves are generated by lightning activity or geomagnetic storms driven by the Sun, and are at the lower end of the radio spectrum, between 100 Hz and 10 kHz. They are best detected by large antennae, in space or on the ground. British Antarctic Survey detects these radio transmissions at its Antarctic Research Station, Halley, on the Brunt Ice Shelf, which lies beneath the Earth’s converging geomagnetic field lines.

Sound waves are vibrations of air molecules, but these emissions – although they are within the frequency range of the human ear – are a form of electromagnetic radiation (oscillating electric and magnetic fields)  which cannot be heard directly. The recorded emissions can be directly converted to waveform audio files using suitable software. This is what enables us to hear the ‘sounds of space’.

Listen to some sounds made by our planet – Spherics, Whistlers and Chorus

Spherics: A ground-based Very Low Frequency receiver, such as the one at Halley, can detect signals from lightning activity. Each lightning flash emits a short radio pulse, known as a spheric, which covers a wide range of frequencies. These are heard as short cracks and appear as vertical lines in a spectrogram. Most of the spherics that are detected at Halley come from lightning activity over the Amazon and Congo basins, both over 8,000 km away!

Whistlers: Some of the radio waves from lightning strikes leave the atmosphere and leak into space, before being guided by the Earth’s magnetic field and received in the opposite hemisphere. Higher frequency waves travel faster than lower frequency waves, so whistlers have a characteristic descending tone.

Chorus: Unlike whistlers, chorus emissions are generated deep within the magnetosphere itself. Energetic electrons enter the magnetosphere during geomagnetic storms driven by the Sun, causing the Earth’s beautiful aurora and generating chorus emissions.

‘Sounds of Space’ talk and performance

Nigel Meredith has been working with artist-engineer Diana Scarborough to find novel ways of visualising space weather data. The ‘sounds of space’ formed the starting point of this exciting venture and inspired Diana to create soundscapes by combining the mesmerising sounds with original visual sequences. We have since engaged with leading Australian composer Kim Cunio and professional dancers Becky Byers and Felix Denton to develop the works into a multidisciplinary show. Our first show, which included a scientific presentation followed by a performance with animation, contemporary dance and soundscapes, was performed at the Cambridge Science Festival in March 2018. Following on from the success of this event, Kim Cunio travelled from Australia to play live in our second show at the BAS Aurora Innovation Centre in November 2018.

Watch the ‘Sounds of Space’ Live broadcast (from Friday 16th November, 2-3pm)

In October 2019 a new immersive performance of the ‘sounds of space’ was showcased at the Cambridge Festival of Ideas. This show included vibrant, experimental, contemporary dance, in which the dancers moved through the audience and space as they responded  to the sound-led, data-driven journey from Antarctica to beyond the galaxy. The dynamic performance was followed by a serene meditative experience, led by Diana Scarborough, featuring ‘sounds’ from the VLF receiver at Halley, images of Antarctica and the beautiful piano music of Kim Cunio.

In June 2024, we presented new interpretations of the ‘sounds of space’ during four exciting shows on The Laboratory Stage at Glastonbury. Kim Cunio gave presentations on the ‘sounds’ of space, followed by performances by Kim Cunio and Heather Lee accompanied by visual sequences from Diana Scarborough.

We have also given talks on the ‘sounds of space’ and our art-science collaborations at the Polar Educators International Conference in Cambridge in April 2019, at the Bluedot Festival, Jodrell Bank Observatory in July 2019, at the Cambridge University Astronomical Society in March 2020 and February 2022, at the Ecoart TECH zoom webinar in November 2020, during the Aerobility Armchair Aurora livestream in March 2021, the 44^th COSPAR Scientific Assembly in July 2022, the Cambridge launch event of Our Place in Space in July 2022 and at the Aerobility Aurora 23 reception in February 2023.

‘Sounds of Space’ feature in space simulation game

The ‘sounds of space’ from Halley have been incorporated into the exploration gameplay in Elite Dangerous. In this unique collaboration Nigel Meredith worked with Frontier Developments, the creators of Elite Dangerous, to incorporate the eerie sounds into the new gameplay. In any one of over 400 billion stellar systems, players can now use a new analysis mode to discover more about their surroundings. The new mode, called the Full Spectrum System Scanner, features the simulated sounds of radio emissions from exoplanets in remote stellar systems based on the Halley VLF recordings. The update, entitled Elite Dangerous: Beyond – Chapter 4, was released on 11^th December 2018.

Elite Dangerous| Frontier Developments

Elite Dangerous is a space-flight simulation video game in which players take control of their own starship and can fight, explore and travel throughout a realistic three-dimensional model of the Milky Way galaxy. Elite Dangerous, launched in 2014, is the fourth game in the Elite video game series and, as of 15^th January 2019, cumulative sales of Elite Dangerous had exceeded 4.3 million franchise units.

Short films at the Venice Biennale

Nine one-minute short films, based on the animations, music and ‘sounds’ from our show, were shown as part of a film installation at the world famous Venice Biennale in 2019. The installation, which was screened from 8^th May to 4^th June at the historic Palazzo Pesaro Papafava, is part of ‘Alive in the Universe’, an art-film project that explores our emotional explanation of the universe through arts and ideas.

Listen to the ‘sounds of space’ accompanied by music from a grand piano

Aurora Musicalis is a sonic experiment, combining the ‘sounds’ from the VLF receiver at Halley with original music. The new work, released on 6^th May 2020, allows us to hear the ‘sounds of space’ accompanied by Kim Cunio’s original music played on a grand piano. The complete 90 minute work comprises 11 tracks revealing the diurnal variations of the audio frequency signals, collected from Halley in one day with piano music also put together in one day. The album, available for free on bandcamp, also includes a 3-minute compilation, sonic highlights from the 24 hour period, set to the music of the opening track and the highlights on their own so that you can create your own musical or visual response to the raw Halley ‘sounds’.

“The benefits of the music are multiple, they reduce stress and pain, improve concentration, rest at night, among many others.” Fahrenheit Magazine.

Since its release music from Aurora Musicalis has featured on a number of radio shows, including Sunday Night Chill Out on Manx FM, the Fogcast on Resonance FM, the Space Station and the Independents Only Ambient Special on Skylab Radio, Clubglobal on Cambridge 105 Radio and The Magic Window on Mad Wasp Radio. Furthermore, tracks from the album have been included on two ambient playlists, “Ambient Autumn – Orbit III” and “Ambient Music for Ambient People: 10 Change“.

Join us on a Journey From Earth to Beyond the Galaxy

Celestial Incantations, launched on 21^st June 2021, builds on our previous album by introducing a whole new “spectrum” of space ‘sounds’ and a huge musical palette, including orchestral instruments, traditional instruments and electronics. The album, which is free to hear and download from bandcamp, takes the listener on a journey from Earth to the largest definitions of cosmic time and space. It invites us to consider the vastness of space, imagining time and space in the grandest sense, and embark on a spectacular journey of sound. Starting off at Earth and moving outwards you will hear compositions inspired by and featuring the ‘sounds’ of our planet, Mars, a comet, Jupiter, Saturn, interstellar space and a galactic pulsar. The album concludes with a track featuring the ‘sound’ of the merger of two black holes, as evidenced by the first observed gravitational wave, an almost unbelievable ripple in space time that Einstein doubted humans could ever capture!

Listen to the ‘Sounds’ of the Sun

Sunconscious, released on 1^stDecember 2022, features music inspired by the Sun. Like our previous albums, this work is a fusion of art and science and a type of dreaming of how art and science can tell the great stories of our time. The album begins with an awakening on Earth with a track featuring the ‘sounds’ of space as recorded by the Halley VLF receiver on the day of the first sunrise following the long austral winter. We then move out into interplanetary space and encounter tracks inspired by and including the ‘sounds’ of plasma waves in the solar wind as captured by the Fields Experiment on the Parker Solar Probe. In amongst this intriguing mix we include tracks featuring the Sun’s natural vibrations as detected by the SOHO Michelson Doppler Imager and a type III solar radio burst recorded by the Radio Wave and Plasma Science instrument on the Cassini spacecraft. The album ends back on Earth at Halley VI, with recordings from the VLF receiver on the day of the last sunset before the long austral winter.

Sunconscious. Music Video

The album, which is free to hear and download from bandcamp, includes 4 minute compilations of the music and space ‘sounds’ and the space ‘sounds’ on their own, so that you can create your own musical or visual response to the raw ‘sounds’ of the Sun. The first track from the album, “First Light”, also features on a compilation album, IP_DT_Vol.1, by Kate Bosworth to be released by Irregular Patterns on 27 January 2023. Music from Sunconscious has appeared on the Dark Train (MA#29,  MA#32, MA#33, MA#37,  MA#51 and MA84) on  Warminster Community Radio, the Phantom Circuit (#370 and #374) on Beachy Head Radio, the Institute of Spectra-Sonic Sound (10:29.22) on KEPW 97.3 FM, and Variant 13 (#23) on Radio Buena Vida, the Fogcast on Resonance FM and two playlists: Neptune’s Selector: Swimming in Space and Ambient Autumn – Orbit V.

Listen to the ‘Sounds’ of a Solar Storm

In In Aurora’s Garden, released on 14^thDecember 2023, we experience the solar storm of 17^th June 2012. A few days prior to this, on the 13^th and 14^th June, two large explosions on the surface of the Sun released bursts of charged particles and magnetic field which travelled outwards and towards the Earth. The material reached the Earth on the 17^th June, the day chosen for our album, tearing open the Earth’s magnetic field, leading to a geomagnetic storm. Particles were injected into near Earth space giving rise to radio emissions including chorus and plasmaspheric hiss. At lower altitudes electrons rained down on the Earth’s upper atmosphere leading to some beautiful and stunning displays of the aurora. We hear the crackles and pops of lightning spherics, the descending tones of whistlers, the rising and falling tones of chorus and the steady hum of plasmaspheric hiss. The musical response is wide and varied and includes gongs, wood blocks, bells, vibraphones, glockenspiels, the piano, a synthesis rig, the Japanese shakuhachi and the tabla. We also hear soprano Heather Lee, in Kim Cunio’s setting of a traditional Chinese text, as well as a new version of the Joni Mitchell classic Both Sides Now. Artwork produced by multimedia artist Diana Scarborough, inspired by Antarctica, the space weather data and the music, adds a rich visual element to the album.

In Aurora’s Garden – Album Cover

Music from In Aurora’s Garden has appeared on the Dark Train (MA#94, MA#96 and MA#99) on Warminster Community Radio, the Institute of Spectra-Sonic Sound (1.6.24) on KEPW 97.3 FM, the Phantom Circuit (#409) on Beachy Head Radio and Mixed Feelings (#58) on Skylab Radio.

Experience the Sounds of an Antarctic Expedition

In The Seventh Continent, pre-released on 12^th June 2024, we take you on a journey with the British Antarctic Survey’s 2023 Antarctic mission to experience the wonders of Antarctica through sound, music, and image.The work is inspired by audio recordings taken by Kat Turner, from the Polar Oceans team, during her recent visit to Antarctica on board the RRS Sir David Attenborough for the BIOPOLE project.

The Seventh Continent – Album Cover

In the album, we experience the wonders of our seventh continent through recorded sounds of sea-ice crushing, charismatic seals, and falling snow among others, put to music and image. The album was pre-released on bandcamp on 12^th June to coincide with a special preview of the album following a talk given by Kim Cunio during his recent residency at BAS.

Music from The Seventh Continent has appeared on the Dark Train (DDIX B.10101) on Warminster Community Radio and The Space Station (#006) on Skylab Radio.

‘Sounds of Space’ feature in contemporary artwork

In a separate project Nigel Meredith collaborated with the art group Troika, resulting in the inclusion of the ‘sounds of space’ in a new artwork. The work, entitled Terminal Beach, is a computer animation film featuring a robotic arm, dressed in long black hair, chopping down what is very probably the last tree on Earth with a haunting soundscape featuring recordings from the Halley VLF receiver. This work was displayed at the Real Feelings Group Exhibition at the House of Electronic Arts, Basel from 27^th August to 15^th November 2020, at the Real Feelings: Emotion and Technology Exhibition at the Mu Hybrid Art House in Eindhoven from 11^th June to 12^th September 2021 and as part of a solo exhibition entitled “No Sound of Water” at the Arte Abierto in Mexico City from 12^th November 2021 to 15^th May 2022. The work is currently on display at the beautiful MAK Museum in Vienna and will be shown at the Langen Foundation in Dusseldorf in September.

Lightning spherics feature on bonus album

In another exciting development, the crackles and pops of lightning spherics recorded by the Halley VLF receiver, can now be heard in a new release by Letters from Mouse. The track, entitled “Confused By The Simple”, forms part of a bonus album which accompanied the release of An garradh on Subexotic Records on 16^th April, 2021.

St Swithin’s Day Storm

The ‘sounds of space’ recorded during a geomagnetic storm appear on the album by Letters from Mouse featuring Dr Nigel Meredith.  In this album, Steven Anderson, aka Letters From Mouse, takes us on a journey through the various stages of the storm, using raw and processed space ‘sounds’ from the Halley VLF receiver. The processed sounds form the bedrock of the album and were created by running the VLF recordings as samples into his modular system, resulting in some weird and wonderful electronic music. The music is accompanied by a voiceover by Nigel Meredith explaining the space ‘sounds’, and, more generally, space weather and its potential impacts on the performance of technology in orbit and on Earth. The storm itself, which peaked on St Swithin’s Day (15^thJuly) in 2012, was accompanied by some sustained and enhanced chorus emissions and the gradual acceleration of electrons to relativistic energies at geostationary orbit, potentially increasing the risk to communications satellites operating in this region. The album, St Swithin’s Day Storm, was released by Subexotic Records on 24^th February, 2023.

Music from St Swithin’s Day Storm has featured on Radio Dark Tunnel, The Dark Train (MA#46 and MA#49) on Warminster Community Radio and The Space is the Place Radio Show (26-01-23 and 02-02-23) on Cando FM.

Earth, What Did You Say?

The ‘sounds of space’ feature on an exciting new ambient album, “Earth, What Did You Say?“, by dReaMSoaKeR. For the various versions of “Earth, What Did You Say?”, VLF recordings from 19th July 2012, a day full of a rich variety of space “sounds”, were incorporated as an ambient “bed” for inspiration and to set the tone for the music. Some were left as is and some were pitched up or down. THX Spatial was incorporated to give each 1 minute file its own space. An edited “whistle” or “Swoosh” was looped to provide a drone like beat that repeats throughout. The music was then improvised as the VLF recordings provided the inspiration and “conducted” the direction of the music. For the tracks “Warble And Chatter” and “Chattering Warriors”, two distinct files were combined (one on the right channel and one for the left). These “warble and chatter” recordings, available as tracks 11 and 12 on the Halley VLF Recordings album, provided a haunting yet euphoric backdrop for the ambient music which it inspired.

Earth, What Did You Say?

P1anets

The ‘sounds of space’ also feature in a sciart composition entitled P1anets by Steev, a technologist with a penchant for combining art and science in myriad ways, often uncovering hidden patterns or unlikely coincidences. Previously, he created “Symphony No.1 in C# minor“, an entire work based around the single idea of asynchronous timing. He lives in Cambridge, surrounded by too many books.

Research Station

The sample sounds on this page were produced from radio waves detected by the Halley VLF receiver at Halley VI, Antarctica. It is a good location to record the ‘sounds of space’ as it is magnetically connected to the outer radiation belt where Extremely Low and Very Low Frequency signals are generated, and is electromagnetically “quiet” as it lies far from man-made sources.
