Far from the booming space battles and roaring warp drives of blockbuster movies, we think of the airless immensity of outer space as being as quiet as it is empty—but it is, in fact, as noisy as anywhere on Earth. But what kind of noise is this? To try and answer that question with his installation, Andrew Williams gathered sounds and data from space—including recordings made by satellites and long-wave radios.

The sound for the installation comes from two main sources:

  • Electrons hitting the Earth’s upper atmosphere – recorded using Long Wave Radio by Cluster II satellite on the 9th of July 2001. The recording is entitled Chorus. The title comes from the brief, rising-frequency tones caused by the impacts of electrons, which sound like a chorus of birds singing.
  • A deep pulsing sound emanating from the Sun, recorded by the European Space Agency Soho spacecraft and caused by bubbles emanating from deep within the star.

The unique project involves projecting the sounds through multiple speakers and also features projections of still images and videos on multiple screens.

Trajectory will develop over the two days—immersing visitors in the artist’s vision of Earth, and space, as well as an exploration of current research and future challenges for humanity.

As well as Earth’s relationship with the sun and “space weather”—the kind of phenomena that produced the sounds—Andrews’s installation explores the history of our relationship with space from Sputnik to the present day. To create the visual imagery for the show Andrew tracked the trajectories of 250 satellites that are looking at the Earth.

Andrew said: “The installation itself looks at several aspects of space in detail, whilst also providing an opportunity to reflect upon the future in terms of future space research, the effects of space research upon our lives and the big question – the future of humanity. No answers are provided, of course!

“The sound is what inspired me – once I had started to create audio from space data I wanted to find a way of presenting it. Much of the data comes from Satellites (in particular Cluster II) and it seemed natural to find the exact location of this when the data was collected. I then realised that the trajectories of satellites created a transfixing and beautiful visual landscape. It also shows how much—or little—of space we currently colonise.”

Andrew Williams became one of the University’s Artists in Residence in 2012, and began a mission with the Space Research Centre to explore new ways of presenting and explaining scientific research to the public.


Andrew Williams de la Centrul de Cercetări Spaţiale din Leicester a folosit datele colectate de sateliţi şi de navete spaţiale pentru a genera sunetul pe care l-am auzi dacă am regla un radio în timp ce ne-am afla în spaţiu.

Cea mai impresionantă realizare a cercetătorului este „Chorus”, o înregistrare ce surprinde zgomotul făcut de electroni în timp ce lovesc atmosfera superioară a Pământului. Sunetul produs de acest fenomen se aseamănă cu cel făcut de nişte grauri aflaţi deasupra unui pârâu.

Sunetul a fost înregistrat de satelitul Cluster II în 2001 folosind un receptor de bandă largă. Williams afirmă că sunete erau în afara spectrului auzului uman, astfel că a fost nevoit să reducă înălţimea sunetelor şi să le filtreze pentru ca oamenii să le poată auzi. (Traducerea via


CHORUS consists of brief tones which sounds like a chorus of birds at daybreak created when electrons hit the Earth’s atmosphere. This new audio composition has been created for the Trajectory Installation at Leicester University by Andrew Williams. It makes use of data collected by the Cluster 2 Satelite in 2001 using LWR (long wave radio) Through a process of transposition and filtering the signal (which are naturally outside of the range of human hearing) the tones become audible. Andrew has shaped the material and developed a performance structure using a multi speaker difussion system to recreate the spatial qualities of the Earth Chorus within the gallery space. Andrew is Leverhulme Artist in Residence at the Space Research Centre, Leicester University.
