Delighted to share the news that I have been longlisted for The Aesthetica Art Prize 2024. A live recording of The Breath of Stars will be included in the digital showcase at York Gallery. The Aesthetica Art Prize celebrates contemporary art across a range of media and I’m looking forward to joining the Future Now conference for critical and cultural debate running alongside the art prize exhibition.

The Breath of Stars (Cosmic ray detectors, mini computers, wooden box (20×20 cm), video projection; live duration) is a digital video work activated in real time by the passage of cosmic rays through a pair of scintillator detectors. Cosmic rays from exploding stars or other extreme events, power across the universe, collide with atoms in the Earth’s atmosphere, break apart, and shower down upon us. Some particles silently interact technology on Earth. In this work, particle detectors and mini computers are connected to a projector. Every time a cosmic ray passes through the plastic scintillator blocks inside the detectors, its energy is recorded, and a starburst video is displayed.

The kaleidoscopic video images that appear are created from mirrored footage of cosmic ray trails filmed during my cloud chamber experiments. Cosmic rays are subatomic  – smaller than an atom – they are protons or the nuclei of an atom which has had its electrons ripped away. We can’t see the actual particles but we can see the trails of condensation they leave behind as they whizz through a cloud chamber.

Cosmic rays arrive at Earth randomly, and this can be witnessed by the sudden flurries and silent gaps of the video imagery. The kinetic energy in just one particle can be equivalent to the energy of a cricket ball bowled by the fastest bowler on the planet  – so much energy squeezed into one tiny particle gives it a huge velocity. Light travels a thousand billion kilometres in one year – a light year – no object with mass can travel at the speed of light but an ultra-high energy cosmic ray would only lag behind the photon by 100th of the diameter of human hair. Most cosmic rays heading for Earth are deflected by the planet’s magnetic field – without this protection, life on Earth, as we experience it, could not survive this bombardment of radioactive matter.

Around 95% of the universe is ‘dark’ to us, formed of unknown and possibly unknowable matter. Phenomenon such as dark matter may be inaccessible to us, but cosmic rays offer a more tangible contact with outer space as they have mass. Although too small to see, we can witness their effects via technology, such as that used in The Breath of Stars, which affords us the opportunity to gaze beyond and between the stars to gain an insight into the structures of the cosmos and imagine what might be hidden in those dark spaces.

I am very excited that Cosmic Chiasmus: crossing the universe is showing at the super brand new Science Gallery Bengaluru in their inaugural exhibition CARBON: under pressure.

Science Gallery Bengaluru (SGB) is part of the Science Gallery International Network pioneered by Trinity College Dublin. The exhibition explores the ubiquitous nature of carbon, its energy history and the potential futures it enables. Given its unique capability to form bonds and compounds carbon is a foundational element of both life and non-organic matter and its properties have been harnessed as fullerenes, graphene, nanobuds, nanotori, nanocones, and nanohorns, enabling the creation of new screens, batteries, ultra-fast computers, ultra-thin sensors and cables of braided nanotubes. Carbon-14 in organic materials serves as the basis for radiocarbon dating, and Carbon-12 was the standard Dmitri Mendeleev used to determine the atomic weights—and now mass—of all other elements. Carbon dioxide is used as the standard to understand and regulate the flow of exchanges between ecology and economy. Industry driven by coal and oil-fired productivity have triggered alarming climatic effects and created a chasm between geo-biological time as shaped by the material memories of the planet and historical time—that shaped by human action. Carbon is an archive of buried sunshine, bridging the divide between substance and phenomena; caught between the finitude of nature’s resources and the near infinite wonderous potential it holds.

Cosmic Chiasmus: crossing the universe offers a glimpse into a subatomic world where cosmic rays travel from distant galaxies to collide and silently interact with atoms and technology on Earth. Cosmic rays are particles that move extremely fast. They are raining down on planet Earth all the time. Although they are called rays they are not like photons, as light is made of, because they have mass, but they do travel at nearly the speed of light. Cosmic rays go through a violent process of creation, transformation and decay. From the heart of stars or the depths of black holes these particles power across the universe with unimaginable energy colliding with life on Earth and triggering other processes such as cell mutation, computer data corruption and carbon-14 formation. Above our heads where cosmic rays collide with atoms in Earth’s atmosphere radioactive carbon-14 is formed. This radioactive carbon-dioxide in our atmosphere is absorbed by plants and enters the food chain. The radiocarbon decays while an organism is alive but is continually replenished as long as the organism takes in air or food. When an organism dies no more Carbon-14 is absorbed and that which is present starts to decay at a constant rate. By measuring the radioactivity of dead organic matter, the carbon-14 content can be determined and the time of death established. Cosmic ray activity gives us carbon dating techniques. It is an incredible journey that cosmic rays make, blasted across space, spiralling along magnetic field lines to end up entangled with carbon in our bodies.

The James Webb Space Telescope selfies of its own light searching mirrors shows cosmic ray activity impact. Space weather can have serious implications for technology. Satellites are particularly vulnerable. and can be sent off-orbit or suffer electrical interference. The satellite population orbiting Earth has more than doubled since 2020, and with more satellites launched in the past year than during the first thirty years of the Space Age, reliance on this technology is increasing at a rapid rate.

I am making new work looking at information insecurity caused by space weather for an upcoming group show at APT Gallery which takes the lifeboat as a metaphor for precarity. Participating artists: Rachael Allain / Caroline AreskogJones / Beverley Duckworth / Liz Elton / Susan Eyre / Kathleen Herbert / Kaori Homma / Anne Krinsky.   

Life Boat brings together artists with a shared interest in exploring precarity as a site of dynamic transition. Each takes an investigative approach to the environmental, social and historical themes evoked by the lifeboat, as a means of addressing ecological crisis, liminal landscapes, close and distant horizons, boundaries and displacement, lines of rescue, navigation and transformation.

“How do you calculate upon the unforeseen? It seems to be an art of recognizing the role of the unforeseen, of keeping your balance amid surprises, of collaborating with chance, of recognizing that there are some essential mysteries in the world and thereby a limit to calculation, to plan, to control.” Rebecca Solnit, A Field Guide to Getting Lost

Gallery Visits

Tania Kovats as above so below at Parafin. She says: ‘I make drawings more than I draw drawings.’ There is something captured in the simplicity of her work, a haptic viscerallity that is very emotionally stirring.

Hiroshi Sugimoto: Time Machine at Hayward Gallery. Beautifully crafted, astonishing work. Hard to believe his models are waxworks or museum taxidermy dioramas, not living subjects and that it is his studied use of light that so cleverly activates his images. I particularly like the Theatres series where he set his camera on an exposure equal to the length of the film being projected into an otherwise dark and empty cinema. The resulting images of a blinding white screen bleeding light like an opening to heaven are remarkable records of passing time. I also loved the work stemming from his interest in mathematics and optical sciences and his experiments with different electrical discharge tools. Sugimoto discovered that he could produce shapes that looked like amoeboid organisms, so he set out to recreate the conditions of the ocean from the time that life began. Using rock salt from the Himalayas (today’s mountain range was once the ocean floor), he mixed his own primaeval seawater. Submerging electrically charged film into the water, the artist was amazed to see light particles move across the surface like microorganisms.

SEISMIC: ART MEETS SCIENCE at GIANT Gallery, Bournemouth, a collaboration with SEISMA Magazine curated by Paul Carey-Kent who was leading a tour of the works when I visited. Artists: Uli Ap, Edward Burtynsky, 0rphan Drift, Peter Matthews, Claire Morgan, Elpida Hadzi-Vasileva, Lisa Pettibone, Shuster + Moseley, David Rickard, Troika. Scientists from corresponding fields of interest are called upon to comment on the work of the curated artists. I was curious to see David Rickards Cosmic Field (3.7mHZ) – a commission by Seisma magazine – which sees cymbals clash when a cosmic rays passes through a hidden Geiger counter. Unfortunately, I didn’t get to witness the full effect as the detector mechanisms hadn’t been charged up, and so only one cymbal was responding with an occasional clash. There are some clever maths in the title and references to John Cages silent composition and the oscillations of the sun. I would like to have learnt more about how the Geiger counters can be sure they are recoding cosmic rays and not just background radiation. It was interesting to read about how stars have sound trapped within and resonate at natural frequencies, like waves inside a wind instrument. Astrophysicist Dr William Chaplin refers to this process as gentle breathing which can be seen in periodic changes in brightness as the stars breathe in ( compressed and bright ) breathe out (relaxed and darker). Other work in the show included Lisa Pettibone’s Truth to Illusion a screen that appears to show a digital undulating image is revealed through a peep hole to be caused by a rotating light and glass mechanism. Light can reveal and mislead in the quest for an understanding of reality. Jewell of Space by Claudia Moseley and Edward Shuster is a mesmerising moving sculpture of light refracting and scattering across a constellation of glass, shadowing the lensing effects of light across the galaxy. Clare Morgan’s Heart of Darkness – a grid of bluebottle flies – a comment on complexity in a system and the importance of each individual to create a whole. Elpida Hadzi-Vasileva’s animal organs given new context – the body turned inside out (cow’s stomach) – the unseen revealed (lamb intestine).

The Accurate Perception Available When Our Eye Becomes Single at The Cut, Halesworth, Suffolk. A lucky chance to see another iteration of this impressive collaboration between Richard Ducker (video) and Ian Thompson (sound). This atmospheric multi-screen installation transports you to the remote otherness of Orford Ness with its innate aura gained from status as a top secret military site and atomic development centre of the 1950’s.

Holding Cosmic Dust: An Almanac, a video installation at The Swiss Church in London by Hot Desque. I enjoyed their previous theatrical inspired installation at Thames-side Studios Gallery where lighting played a key role in creating atmosphere. Again lighting was key, this time very low lighting meant identifying friends at the event was unpredictable. This installation is partnered with an intervention within the permanent, archaeological collection of the Corinium Museum, in Cirencester, positing a speculative archaeological dig in which a matriarchal society is uncovered. The installation draws out connections between archaeology, history and fantasy. There was in conversation with historian Frederika Tevebring about the speculative nature of archeology and evidence of matriarchal societies, but due to challenging acoustics and lighting much of this fascinating talk was lost. I would have liked to hear about the cosmic ray connections. Was it to do with Carbon dating? Participating artists: Holly Graham, Rubie Green, Rebeca Romero, Amba Sayal-Bennett, Abel Shah and Suzanne Treister.

Reading

All The Light We Cannot See by Anthoney Doerr. An extraordinary evocation of the depths of human tenderness and cruelty and the power of knowledge. This is a beautifully written fiction spanning the decades from the 1930’s into the 21st century when advances in radio technology went from a being a source of public information and enlightenment to a weapon of war. Through the wonder of the young protagonists in discovering the magic of radio transmissions, the author also stirs in the reader a reminder that it is invisible waves crisscrossing our world, carrying information vast distances, across political and geographic boundaries. I loved this book.

The Future of Geography: how power and politics in space will change our world by Tim Marshall. Clear and accessible writing takes the reader through the history of the space race to the ubiquity of orbiting satellites and on to the era of astropolitics, military strategy and the battle for future resources. The stakes are high.

Entangle: Physics and the Artistic Imagination edited by Ariane Koek, written in conjunction with an exhibition at Bildmuseet in Sweden. The book is filled with fascinating essays from both artists and scientists giving personal perspectives on their interest in and interaction with particle physics. The importance of an open imagination, the thrill of the unknown, the quest for knowledge that may never be accessible, are relevant to all participants. The common ground between art and science, and the benefits to both fields of joint conversations, is increasingly being acknowledged. Scientists offer the abstract theories, controlled experiments or new technologies that feed artists imaginations, throwing up new questions for both to consider and relate to the human experience.

Watched the deeply moving film by Werner Herzog, The Enigma of Kaspar Hauser – a fictionalised documentary of a teenager suddenly released from an existence of inexplicable confinement chained in a cellar with no human contact other than his captor. The film follows the internal struggle of Kaspar as he is subjected to the demands of society, and take on the current belief systems of the Church. His confusion at the world and despair at how much he doesn’t understand is an allegory for the limitations of human knowledge. The film spotlights the failure of logic and science to provide answers to the human condition.

Editing footage for the video Belly of a Rock which will be shown on an old monitor encased in a sculptural hybrid form relating to both mollusc and rock. The giant sea slug of the mollusc family, can derive directional cues from the magnetic field of the earth which is then modified in response to the lunar cycle. It orients its body between north and east prior to a full moon. In the slug’s nervous system, four particular neurons are stimulated by changes in the applied magnetic field, and two are inhibited by such changes suggesting that the animal uses its magnetic sense continuously to help it travel in a straight line.

The Earth can be divided into the inner core, the outer core, the mantle, and the thin crust. The outer core is about 1,367 miles thick and mostly composed of liquid iron and nickel. It is very malleable and in a state of violent convection. The churning liquid metal of the outer core creates and sustains Earth’s magnetic field. At the boundary between the inner and outer core temperatures can reach 6,000° C which is as hot as the surface of the sun. The inner core is a dense ball of mostly iron, but with a temperature above the melting point of iron, it is not liquid or even molten. Intense pressure from the rest of the planet and its atmosphere prevents the iron inner core from melting as the iron atoms are unable to move into a liquid state. It could be described as a plasma behaving as a solid. The inner core rotates eastward, like the surface of the planet, but it’s a little faster, making an extra rotation about every 1,000 years.  Geoscientists think that the iron crystals in the inner core align north-south, along with Earth’s axis of rotation and magnetic field and are arranged in a hexagonal close-packed pattern. The orientation of the crystal structure means that seismic waves travel faster when going north-south than when going east-west. Seismic waves travel four seconds faster pole-to-pole than through the Equator. 

The Earth is still cooling and as it does so, bits of the liquid outer core solidify or crystallize causing the solid inner core to grow by about a millimetre every year. The growth is not uniform, it is influenced by activity in the mantle and is more concentrated around regions where tectonic plates are slipping from the lithosphere into the mantle, drawing heat from the core and cooling the surrounding area. The crystallization process is very slow, and further slowed by the constant radioactive decay of Earth’s interior. Scientists estimate it would take about 91 billion years for the core to completely solidify but the sun will burn out in just 5 billion years. 

I have nervously passed the cosmic ray detectors over to programmer Jamie. It was hard to let them out of my sight after so much work to get them built but he can’t test the code he has written without them. The Breath of Stars directly interacts with cosmic rays in real time to trigger a digital reaction via a mini computer attached to a block of plastic scintillator and a sensitive photomultiplier. As each particle strikes the plastic scintillator its energy is recorded and a starburst image video relative to the energy released is projected, with the largest images representing the particles with the highest energy.

I am constructing an Obelisk sculpture in response to the concrete obelisk erected in 1955 at Hartland Magnetic Observatory, near the site’s northern boundary as a permanent azimuth mark. It is viewed via a theodolite through a window in the north wall of the Absolute Hut, its azimuth being 11º27’54” E of N and marks the point from which the magnetic north pole is tracked as it drifts westwards. Layers of torn recycled paper are stacked like sedimentary rock that holds clues to the Earth’s magnetic field reversals in its strata.

Copper contours of magnetic field lines have been lacquered to preserve the heat patina from plasma gun cutting. These shapes will be pinned to the north facing mossy wall of the Absolute Hut installation, a reimagining of the Absolute Hut at Hartland Magnetic Observatory. I will also employ a north facing window from which to observe the azimuth mark of the Obelisk sculpture.

A second research visit to RSPB Snettisham, this time to see the pink footed geese (which over winter on the mudflats here) leave their roost at dawn to fly to the fields to feed.

The walk from the car park to the viewing area is over 2km and takes about half an hour to walk. Setting out before first light the weather felt promising but just as I erected the camera tripod the rain came down hard and didn’t stop for the rest of the morning.

Made a second attempt the next morning leaving a little earlier and although it remained dry there was heavy fog over the sea. Not great for filming with my very basic kit but very atmospheric to experience as the geese emerged from the sea mists.

The noise they make is incredible, a constant chattering building to a crescendo of honking calls as they rise from the water and swarm across the sky in their hundreds. They come in waves but look like particles. At one point what sounded like a few gunshots fired out across the bay in the distant darkness. This sudden disturbance set off a slow deep rumble which drew closer accompanied by a low dark cloud growing heavily stronger building and rising as a huge tidal wave of geese rose simultaneously into the sky in panicked disarray. Extraordinary to witness.

Birds are able to “see” Earth’s magnetic field lines and use that information for navigation. Their compass ability comes from a quantum effect in radical pairs, formed photochemically in the eyes. This light sensitive magnetic compass used by birds is affected by the polarisation direction of light. Exposure to blue light excites an electron, which causes the formation of a radical-pair whose electrons are quantum entangled, enabling the precision needed for magnetoreception.

In chemistry a radical is an unpaired electron which is can be highly chemically reactive. In the radical pair mechanism a pair of electrons with opposite spins have a chemical bond. Light can cause the electrons to change spin direction which can break the bond giving the electron a chance to react with other molecules. In magnetoreception two cryptochrome molecules, found in the rod cells in the eyes of birds, each with unpaired electrons, exist in states either with their spin axes in the same direction, or in opposite directions, oscillating rapidly between the two states. That oscillation is extremely sensitive and can detect the weak magnetic field of the Earth. Birds then move their heads to read the spin of the molecules and therefore detect the orientation of the magnetic field.

While in North Norfolk staying in a beach chalet away from light pollution I was able to make a couple of short time lapse videos centering on Polaris.

Birds can detect the slow arc of the sun and the rotation of the constellations across the sky which is imperceptible to humans and allows migrating birds to orient themselves using celestial navigation as well as magnetoreception.

Birds are also able to detect rapid movement such as individual flashes or flickering of a fluorescent light which humans see as a continuous light. Hawks which pursue other birds through dense forests at high speeds, follow the movement of their prey while avoiding branches and other obstacles. To humans travelling at this speed, the fleeing prey, branches and obstacles would just be a blur.

Gallery Visit

Thames-side Gallery ‘The Accurate Perception Available When Our Eye Becomes Single’ is an immersive multi-screen installation evoking the emotional specifics of place (Orford Ness on the Suffolk coast) while exploring the elasticity of time and history. It is an audio-visual collaboration between Richard Ducker (video) and Ian Thompson (sound) with no linear narrative; sound and image are not synchronised, so each viewing is a unique experience. Sarah Sparkes also makes an enigmatic performative appearance both in the video and live in the gallery.

The crashing sea on shingle, open spaces and brutalist bunker architecture of Orford Ness are echoed in the gallery with audio pitched to envelop and resonate but not overwhelm. Nicely done.

Listening

I really enjoy the Inside Science podcasts with Gaia Vince and this one interviewing cosmologist and theoretical physicist Laura Mersini-Houghton about finding evidence that supports her multiverse theory was particularly fascinating.

Multiverses, melting glaciers and what you can tell from the noise of someone peeing

According to Laura the single universe theory is mathematically impossible.

Reading

Merlin Sheldrake’s Entangled Life. A remarkable reveal of an other world, so different yet so entwined with our own. Beautifully clear analogies help to bridge an understanding between human and fungi.

The ability to detect and respond to chemicals is a primordial sensory ability.

In humans when a molecule lands on our olfactory epithelium and binds to a receptor it causes nerves to fire triggering thoughts and emotional responses.

A mycelial network is one large chemically sensitive membrane: a molecule can bind to a receptor anywhere on its surface and trigger a signalling cascade that alters fungal behaviour.

Fungal lives are lived in a flood of sensory information.

They have light receptors, are sensitive to touch and it also looks like fungi may form fantastically complex networks of electrically excitable cells – a potential ‘fungal computer’ using electrical signalling as a basis for rapid communication and decision making which could learn and remember.
