Speculating on a view of the world projected from the perspective of the rock. In the studio drilling more holes for optical lenses set out in a pattern based on the crystal structure of the naturally magnetic mineral magnetite which was determined in 1915 as one of the first crystal structures to be obtained using X-ray diffraction. Found in igneous rocks, sedimentary deposits and sand across the globe in many locations, magnetite is also found in the cells of organisms from bacteria to humans. Magnetite contains both ferrous (divalent) and ferric (trivalent) iron along with oxygen.

Testing projecting through the optical lenses I’m excited to see how the different lenses cause images to overlap and distort.

I received a Digital Microscope for my birthday and a selection of rocks and meteorites to look at. So far I have only used the lens with the least magnification capabilities yet this is revealing wonderful detail in the rocks which are further enhanced by using a polarising filter. I have chosen to look at rocks which originate near areas of tectonic activity or that may have magnetite in them.

Images on left have no filter, those on the right have a polarising filter.

This thin slice of Deep Ocean Pebble was collected in 1979 three miles deep in the Pacific Ocean Clarion Clipperton Fracture Zone. This zone is regularly considered for deep-sea mining due to the abundant presence of manganese nodules. In 2016, investigation of the seafloor in the zone was found to contain an abundance and diversity of life – more than half of the species collected were new to science.

This slice of Lewisian Gneiss is 3 billion years old. These ancient rocks from the Isle of Lewis were caught up in a mountain building cycle roughly 490–390 million years ago and were pushed above younger rocks formed during the late stages of this tectonic event.

This slice of Olivine Basalt comes from Þingvallavatn, a rift valley lake in southwestern Iceland. The area is covered by lava. The cracks and faults around the lake is where the Eurasian and North American tectonic plates meet. This may be the only place where one can stand with two feet on two different tectonic plates. The sample is a mid oceanic ridge basalt (MORB) fine grained but consisting of small olivine, clinopyroxene fragments in ground mass dominated by plagioclase laths, an opaque magnetite.

This slice of Vesicular Basalt Lava – a type of lava that solidifies into a rock with trapped gas bubbles leaving small holes as the lava cools, comes from the Mid Atlantic Ridge near the Azores Islands.

I also have a piece of Jepara taken from a pallasite, a class of stony–iron meteorite, discovered in Indonesia in 2008 during building excavations. The outside is heavily weathered but when cut and polished the inside reveals a translucent structure of densely packed olivine and magnetite. The sample has been coated with acrylic which has surface scratches so I think some of the detail has been compromised but it is still beautiful. No filters used here.

I am making use of public access to historical magnetograms recording of Earth’s magnetic declination to feed into new work inspired by palaeomagnetism. Magnetic studies of the ocean in the 1950’s had determined that the ocean floor was covered by bands of magnetic stripes that varied between normal polarity and reversed polarity. The Earth’s magnetic field has reversed polarity many times over the past hundreds of millions of years. These magnetic stripes were found to be symmetrical on the ocean floor about the mid-oceanic ridge. In 1963 British scientists, Fred Vine and D. H. Matthews proposed that the magnetic striping was caused by paleomagnetism, the storing of Earth’s ancient magnetic field in the sedimentary rocks that were forming as lava spewed up and spread across the ocean floor setting the history of pole reversals in stone.

I have embarked on some crystal growing experiments using a seed crystal in a saturated solution of mono-ammonium phosphate and aluminium potassium sulphate. I am hoping these might become objects to view through a lovely old wooden magnifying box I have. The last time I experimented with crystals was when I was amazed by the speed and glut of salt crystals overwhelming the test area. Before that made a time lapse video over 5 days of crystal growth for the installation Time Crystals in Reading Stones at St. Augustine’s Tower 2019. I will be learning more about this as workshops are developed for The Geological Unconscious public engagement programme which will run alongside the exhibition at Hypha HQ Euston this coming spring. Both Julie F Hill and Sophie Mei Birkin work with crystal structures and growth in their own practices and will be leading on the workshops we will run in partnership with a local primary school.

A crystal is like a class of children arranged for drill, but standing at ease, so that while the class as a whole has regularity both in time and space, each individual child is a little fidgety. Dame Kathleen Lonsdale, 1948

Had some studio fun testing the possibilities of magnetic putty for future video ideas. Mesmerising the way it very slowly swallows the magnet.

I began the magical process of making copper ink. Soaking pieces of copper in vinegar and salt, stirring daily and watching the liquid turn a milky turquoise blue. Looking forward to using this to patinate copper but also to paint with on paper.

Experimenting winding a copper wire around an iron nail and connecting the wire to a battery cell. A magnetic field is generated around the nail which stays for a little while after the nail is removed from the coil. I used a 9v battery and large nail– it wasn’t a very strong magnet – a welding stick was better and seemed to retain the magnetic field for longer but in both cases the battery got very hot. I had hoped to maybe develop this idea to magnetise a sculpture threaded with iron. Needs more investigation.

I have been exploring the updated Digital Materials Library at the Institute of Making which led me to the Mindsets website which has some cool magnetic materials for sale. Future experiments upcoming.

Exploring paper weaving patterns with a view to reinventing past works while thinking about ideas of cosmic planes in The Rosicrucian Cosmo-Conception, a 1909 text by Max Heindel. This text, setting out a theory of seven Worlds and seven Cosmic Planes, supposes an intermingling of spirit with matter where the intersection of the material and metaphysical world are not one above another in space, but inter-penetrate each with the other.

Astonishing that the preserved remains of the ancient kauri trees of New Zealand, alive over 42,000 years ago, can reveal the time of the last significant magnetic pole excursion within their rings. During what is known as ‘The Laschamps Excursion’, the north and south magnetic poles swapped places for about 500-800 years before swapping back again. During a magnetic pole reversal the magnetic field weakens so many more cosmic particles reach the surface of Earth. This means much more Carbon-14 is produced in the atmosphere and absorbed by plants.

Changes in radiocarbon levels were recorded from four ancient kauri logs found buried in peat swamps which seals them in a chemically balanced environment. Through high precision carbon dating processes at the University of Waikato in New Zealand the scientists discovered the most dramatic time was the lead-up to the reversal, when the poles were migrating across the Earth and our magnetic field practically disappeared, leaving life here very vulnerable to cosmic radiation. It appears, this weakening 42,000 years ago, in combination with a period of low solar magnetic activity – captured in evidence from ice cores, caused damage to the ozone layer and disrupted atmospheric conditions impacting the global climate so that devastating environmental changes took place. The research team links this climate change to extinction events which occurred at the same time, Neanderthals vanishing from Europe, and a proliferation of cave paintings appearing in Europe and Asia as humans find shelter from the turbulent weather and increased electrical storms. They have dubbed this period of excursion ‘The Adams Event’ in honour of Douglas Adams who wrote in The Hitchhikers Guide to the Galaxy that ‘42’ was the answer to life, the universe, and everything

Studio Visits

Julie F Hill and I have been visiting the other artists participating in the upcoming exhibition The Geological Unconscious at Hypha HQ Euston. We are so happy to be working with Charlie Franklin who considers control, physical experience and memory within the natural landscape, Deborah Tchoudjinoff who considers what the form is through the process of material and visual experimentations, Rona Lee who centres on the politics and aesthetics of Geo-materiality along with the human /more than-human entanglements of contemporary life and Sophie Mei Birkin who investigates the generative potential in the transformation of matter through a variety of material processes such as growing salt crystals and exploring amorphous and decomposing substances.

I have also been lucky to have Charly Blackburn and Victoria Rance visit my studio to chat about our respective work and shared interests. Charly is beginning a period of research into rare earth materials and extractive processes and we share a fascination with things magnetic. Victoria came to chat about our shared interest in the sun but is also interested in magnetic fields and the potential they offer for brain to brain communication.

Haegue Yang Leap Year at Hayward Gallery. With colourful works festooned by garlands of bells and strewn with fairy lights this was a perfect show for the festive period. Folklore, surrealism and ritual, collage and costumes combine with the modern domestic/utilitarian in hybrid works that have a playful carnival air.

Thoughtful works beautifully presented Each Place Its Own Mind at Edel Assanti with Mirtha Dermisache | Noémie Goudal | Sky Hopinka | Anna Hulačová | Marguerite Humeau | Bronwyn Katz | Kat Lyons | Yukultji Napangati | Emmanuel Van der Auwera. An ongoing collective reimagining of our relationship with the living world, rooted in revelations from indigenous knowledge, ecological research, literature, science, and artistic experimentation. Each Place Its Own Mind  borrows its title from ecologist David Abram’s 1996 book The Spell of the Sensuous, which traces the ways the human mind came to renounce its “sensory bearings” in the natural world, visualising a myriad of “lost” faculties that link the “inner, psychological world and the perceptual terrain that surrounds us.”

Events

A little out of my depth at the A&G Highlights Meeting at The Geological Society where some talks were quite specialised, involving graphs and terminology beyond my understanding. I do enjoy hearing clever people talk though, even if I can’t grasp exactly what they are explaining. A fascinating presentation by writer Nilanjan Choudhury on ‘The Square Root of a Sonnet’, his play which explores the fraught personal relationship between the brilliant Indian-American astrophysicist Subrahmanyan Chandrasekhar and his mentor, Sir Arthur Eddington of Cambridge University who publicly humiliated him at a Royal Astronomical Society meeting 90 years ago to the day. Guardian Article here

Dr Jessica Irving (Bristol University) gave The Harold Jeffreys Lecture on ‘Hearing planetary hearts: seismology of the cores of Earth and Mars’. An engaging speaker, she led us through the milestones of the last 130 years of theories on what is at the centre of the Earth and the discoveries made using seismology.

Dr Chris Lovell (University of Portsmouth) spoke on his research into ‘Accelerated modelling of the entire observable Universe’. I recognised the dark matter simulations and was fascinated by the different views of a galaxy depending on the band of the light spectrum used to observe it.

I joined a sobering Royal Astronomical Society webinar We Need to Talk About Space Junk presented by Professor Mike Lockwood. Our use of space is increasingly limited and threatened by space junk. The concern is that we are heading towards a runaway effect called the Kessler syndrome, in which the debris from one collision causes many others, to the point where space becomes unusable.

I went to see the fast paced RSC production of Kyoto at Soho Place. Welcome to the Kyoto Conference Centre, 11 December 1997. The nations of the world are in deadlock and 11 hours have passed since the UN’s landmark climate conference should have ended. Time is running out and agreement feels a world away. The greatest obstacle: American oil lobbyist and master strategist, Don Pearlman… Set nearly 20 years ago its depressing how little progress was made and we are currently sliding backwards. Would never have guessed it at the time but now am nostalgic for the politics and positivity of the 90’s.

Time to email your MP to join The All-Party Parliamentary Group for Dark Skies. The group’s primary focus is to preserve the night sky within the UK and promote the adoption of dark sky friendly lighting and planning policies. Surprisingly the committee is made up mostly of tories – come on the rest of you!

Go to this link where it is quick and easy to message your MP to act on this important issue.

Watching Chris Packham’s The Wonder of Animals – Foxes A red fox catches its prey using more than pinpoint hearing and an accurate pounce: it also involves alignment to the slope of Earth’s magnetic fields. I contacted Peter Hore FRS, Professor of Chemistry and Magnetoreception expert at Oxford University who was so helpful to me before in explaining how birds ‘see’ the magnetic field to see if he had come across any new research on this. He has pointed me in the direction of other research conducted by the group looking at fox behaviour so this is something I will pursue further.

Listening to What? Seriously?? with special guest Helen Sharman, the first British astronaut, about how humans learned to survive in space. Quite a few animals were sent to space before humans including two Russian Steppe tortoises (Testudo horsfieldi), who did a circuit of he moon and returned to Earth – alive but starved. The tortoises were chosen as they have a unique ability in the animal world to resist radiation and their blood may be useful in the treatment of radiation sickness. In recent research a string of amino acids have been extracted from the blood of these tortoises and if you inject those amino acids into other animals they become radiation resistant too.

Listening to The Year in Science 2024 podcast – One of the UK’s first military communication satellites’ Skynet 1a launched in 1969 was abandoned a few years later above Africa. Orbital dynamics should have dragged it out somewhere above India but it has been found wandering above the Americas in a busy area of live satellites and no-one knows why. Space consultants think it must have been commanded to move in the 1970’s but can find no record of this and although research has been undertaken it is still a mystery how this satellite moved. BBC article

There is no mention of a cosmic ray interaction forcing the command, but that would be my theory!

The ‘Art, Science and Creativity’ exhibition at Liverpool’s spectacular Central Library continues. The exhibition is inspired by statements from Albert Einstein, highlighting the fact that creativity is central to explorations in both art and science. As we wonder, and attempt to understand the universe and ourselves, categories can, and perhaps should, become blurred. Distinctions can be both valuable and problematic: ‘art’ versus ‘science’, ‘nature’ versus ‘human’, ‘natural’ versus ‘supernatural’, ‘material’ versus ‘spiritual’, ‘secular’ versus ‘religious’ and so on. And as the great science-fiction writer Arthur C Clarke said “Any sufficiently advanced technology is indistinguishable from magic”.

I am very happy to have two unique books included in the exhibition. In/Out and Unbound.

Liverpool Book Art and Fevered Imagination are collaborating to create a video loop of all the artworks, enabling audiences to get a fuller appreciation of the artists’ creativity than allowed by the use only of display cases. Fevered Imagination is a website dedicated to Artists Books, through which works from the exhibition can be bought.

I am delighted to be invited by Serendipity Arts Foundation to show Cosmic Chiasmus: crossing the universe at Serendipity Arts Festival in Goa later this year.

Serendipity Arts Foundation is an organisation that facilitates pluralistic cultural expressions, sparking conversations around the arts across the South Asian region. Committed to innovation and creativity, the aim of the Foundation is to support practice and research in the arts, as well as to promote sustainability and education in the field through a range of cultural and collaborative initiatives. The Foundation hosts projects throughout the year, which include institutional partnerships with artists and arts organisations, educational initiatives, grants, and outreach programs across India.

Serendipity Arts Festival is one of the largest multi-disciplinary arts initiatives in the South Asian region. It spans the visual, performing, and culinary arts, whilst exploring genres with film, live arts, and literature. Besides the core content, which is conceptualised by an eminent curatorial panel, the Festival has various layers of programming, in the form of educational initiatives, workshops, special projects, and institutional engagements. Through active conversations between the artistic community and the urban, social landscape, the Festival continues to evolve around the mandate of making the arts visible and accessible. The Festival is driven by a spirit of collaboration, hoping to inspire new perspectives and fresh aesthetic encounters. This labour of love is a cultural experiment that also addresses issues such as arts education, patronage culture, interdisciplinary discourse, inclusivity, and accessibility in the arts.

Other exciting news is that Julie F. Hill and myself are working together again on a new project. Following on from our ambitious duo show A Stone Sky at Thames-side Studios Gallery (Nov 23), we will be curating and participating in an exhibition next spring, exploring themes of stone consciousness and human-mineral encounters.

In the studio I have been working on a proposal for the Moon Gallery. Moon Gallery is an international collaborative artwork and a gallery of ideas which aims to set up the first permanent museum on the Moon. Moon Gallery will launch 100 artefacts to the Moon within the compact format of a 10 x 10 x 1cm plate on a lunar lander exterior panelling as early as 2025.

Each sculpture has to fit within a 1cm cube, which is quite challenging. My proposal is a 5mm spherical magnet sparkling with black volcanic sand on a 1cm square of patinated copper. Space exploration means leaving the protective shield of Earth’s magnetic field, placing astronauts and technology at risk from increased levels of harmful high energy particles. This artwork is a small realization of a magnetic field offered as a symbol of safe passage to those venturing beyond our home planet and protection of Earth’s magnetosphere. The black volcanic sand used in this work is naturally magnetic, making visible the force that emanates from the core of the magnet. The patination colour reflects on the astonishing view of our blue planet from the moon and the importance of water to sustain life. The title Core Values, makes reference to the molten core necessary for a planet to generate a magnetic field as well as the ethical principles and beliefs that guide humanity in a positive spirit of peaceful cooperation for the benefit of all. The work operates as a motif for what is in the heart of a body, rocky or otherwise. It also celebrates the beauty of the elements and natural forces that together inspire the human imagination and makes the cosmos so exciting to explore.

I have been sorting out the copper contours from The Absolute Hut (of action potential) as I couldn’t store this work, it had to be dismantled. The copper will be reused in future work.

I am making a new concrete tablet for Instruments of the Anemoi series with more detailed compass rose inspired copper insets. The copper is guillotined to shape and screen printed with a sugarlift solution.

The pieces are then dipped in bitumen and left to dry before putting in a bath of warm water to dissolve the sugar solution, leaving the design ready to be etched.

I also cut some copper shapes to patinate, painting the copper with salt and vinegar and soy sauce before fuming in an ammonia bath. I love how the colours change throughout the process.

I was going to patinate the dodecagon shapes as well but in the test I did, I lost a lot of detail, so these will just be inked and left.

Charmaine Watkiss showing her beautiful drawings full of symbolism in Hard Graft at Wellcome Collection. The exhibition explores the impact of work on health and her works celebrate the ancestral herbal knowledge of medicinal and edible plants and fruits that carry powerful healing properties.

These were used to secretly cure illnesses and prevent diseases as an act of survival and self-dependency, distinct from Western medicine. The connection between herbal healing and African spiritual practices is represented by cosmological symbols discreetly tattooed on the women’s bodies. Natural dyes – such as Jamaica’s Blue Mountain coffee and indigo – and materials such as brass and raffia palm embed historical knowledge in the fabric of the works. This knowledge is preserved, yet concealed, by the figures who avoid the viewer’s gaze.

Rona Lee Lithic Entanglements at Sedgewick Museum of Earth Sciences. A considered intervention in the Whewell Mineral Gallery to ‘bring the dirt back in’, making evident the scarred landscapes, physical extraction processes as well as the social strata of those involved in procuring such a collection. There is no denying the allure of minerals and gemstones and the work here captures the beauty of the rocks while also reminding us of the ravaged Earth left scarred and depleted.

A Modern Lapidary a video work, back projected through one of the free-standing cases, animates mid-century scientific photographs of minerals, altering our perception of the samples within as ‘dead’ matter. Elsewhere, in An Extractive Index, digitally collaged photographs of geological field trips are laminated on to the glass, inviting reflection on the social and environmental relationships which these reveal.’ 

The Museum itself was also fascinating to look round and after Rona’s artist talk we were treated to tea in the The John Watson Building Stones Gallery which houses the most complete collection of stones used in construction.

Emma Stibbon Melting Ice | Rising Tides at Towner Eastbourne. A day trip to the see this remarkable body of work so thoughtfully curated. The pale majesty of ice or chalk cliff faces, fragile against pounding seas that Emma witnesses in both the polar and local Sussex coastlines are captured so poignantly. These are portraits of great bodies under stress. Close up, edges and lines break down into fluid, watery strokes, a diaphanous translation of the fast painterly sketches made in often gruelling conditions. Wonderfully immersive, through scale and placement, and the understated palette of deep muted greens and blues, almost blacks and luminous whites which draw the viewer into the landscapes.

Astronauts and space tourists often cite the overview effect as a transformative experience offering the perspective to see a shared planet with no borders. Some however, experience the ‘ultraview’ effect which is the overwhelming and disorienting knowledge of the magnitude of the universe.

BBC Inside Science Podcast. How much of a risk is space junk? As we send more and more metal in the form of satellites up into space, scientists are warning it is becoming more of a risk both here – and up there.

Much space junk comes from defunct satellites. There are plans to launch 60,000 more satellites by 2030. It is estimated there is currently 12, 400 tons of space junk orbiting Earth – 2,500 discarded satellites and 130 million fragments that travel at 10 times the speed of a bullet. Because of the orbiting junk, Space X satellites must make around 275 collision avoidance manoeuvres every day. It is not only dangerous in space but large debris is falling to Earth and not burning up in the atmosphere. It is predicted life will be lost in the next decade as a result of falling space junk, there have already been some near misses. The satellites and launch debris that does burn up in the atmosphere releases large amounts of metal into the atmosphere with unknown consequences.

In search of huts. I have been on a mission to locate and document the remaining huts from a cosmic ray detection experiment at Haverah Park on the Pennine moorland in North Yorkshire.

When high-energy cosmic rays enter the atmosphere, they set off a chain-reaction particle cascade known as an extensive air shower. The Haverah Park experiment was home to one of the largest extensive cosmic ray air shower arrays in the world.

It was operated by the Physics Department of the University of Leeds for 20 years, closing in 1987. An array of over 200 water-Cherenkov detectors covering 12 km2 were active during its operation and many 1000’s of extensive air showers were recorded, including ones of such size that the cosmic rays that generated them had energies previously unthought of, adding to the mystery of where they come from.

The large energy density of cosmic rays is close to that of starlight, adding their own glow to the sky as they blast across the universe. Cosmic rays are the atomic nuclei of elements ranging from hydrogen to uranium accelerated to high energies, with half being protons and most positively charged.

Much of the technology used to observe cosmic rays has changed little over the decades since first inventions and still plays a role within newer technologies.

It appeals to me that the excitement of observing particles from other galaxies happened at these unassuming structures.

Sharing the landscape of Haverah Park cosmic ray air shower detector array huts are the striking white radomes that shield secret radar equipment at RAF Menwith Hill. The spy station has been there since the cold war space race began in the mid-fifties. Little is known about what goes on here but broadly it is said to gather electronic intelligence and is operated by US National Security Agency (NSA) and UK Government Communications Headquarters (GCHQ). As satellite technology has increased so has the number of radomes which now number 37 at the site. It is worth noting that satellites are vulnerable to unpredictable space weather and cosmic ray interference.

The total number of particles detected in a shower can be used to estimate the energy of the primary cosmic ray. Some particles contain the highest energy form of radiation known to exist anywhere in the universe and their origin is one of science’s greatest mysteries. Air showers of secondary particles generated from a primary cosmic ray hitting the Earth’s atmosphere are spread over many kilometres when they hit the ground so it is useful to have detectors spread over a large area. The difference in the time of arrival of recorded particles at multiple detectors can be used to estimate the arrival direction of the primary cosmic ray. However, this does not necessarily reveal the origin of the particle as magnetic fields within the galaxies bend their trajectories so that the memory of their original direction is obfuscated.

The cosmic ray detectors I made for the The Breath of Stars use a block of plastic scintillator which emits a short burst of UV light when a charged particle passes through it which is picked up by a single-photon-sensitive device. The detectors used at Haverah Park are water Cherenkov detectors. These are large steel tanks of purified water with photon sensitive detectors in the water.

While the speed of light in a vacuum is a universal constant its speed through a material may be significantly reduced as it is slowed by the medium. A particle passing through a material faster than that at which light can travel through the material loses electrons thereby emitting light. When cosmic rays pass through the water tanks, they emit Cherenkov radiation because they travel faster than the speed of light in water. Cherenkov light is similar to the production of a sonic boom when an airplane is traveling through the air faster than sound waves can move through the air. Pavel Cherenkov along with Ilya Frank and Igor Tamm discovered and demonstrated this phenomenon in 1934, astonishingly, it had been predicted in 1888 by Oliver Heaviside, and in 1910 Marie Curie had noticed a strange blue glow from her radium experiments.

Other huts from the Haverah Park experiment are in a state of collapse.

There are so many high energy particles hurtling around the universe that they almost equal starlight in energy density. Cosmic rays travel at almost the speed of light and because they are charged particles most cosmic rays are confined, spiralling within our galaxy for a million years or more, by the magnetic fields which permeate it.

Five million cosmic rays pass through your body each day. Some will collide with atomic nuclei. A particle passing through a material at a velocity greater than that at which light can travel through the material emits light. Maybe we glow a little.

Following the disappearing trail. Haverah Park hut with an intriguing hexagon tank.

Inside Hut no. 7 is a dumping ground. Waste is a big problem in space as well as on Earth. The thickening shell of space junk in low Earth orbit, if left to accumulate, could cause a conductive shield to form, weakening the effectiveness of the magnetosphere, which protects life on earth from most cosmic radiation.

A decaying wall map of the entire Haverah Park experiment is just visible through a window of one of the huts in the central hub, but not much else remains inside.

It looks like these huts have been recently emptied into a skip which, by chance, was collected while I was there. Unfortunately, the driver had no enlightening information for me about the future of the huts.

Cherenkov radiation is a form of energy that gives off a blue glow when electrically charged particles are moving at speeds faster than light is able to travel through the same medium. The experimental physicist Blackett, who received the 1948 Nobel Prize in Physics for his investigations into cosmic rays, believed that extensive air showers should produce flashes of light that could be perceived by the human eye when lying down and looking upwards under dark skies. Whether he achieved seeing this phenomena himself is not known, but he inspired colleagues Galbraith and Jelley, in 1952, to devise an experiment to detect light from air showers using a rubbish bin painted black on the inside, a recycled searchlight mirror and a small phototube. With these simple items, they made the first observation of Cherenkov light produced by cosmic rays passing through the atmosphere. Not all the twinkling in the night sky is starlight.

During the Haverah Park experiment, the water Cherenkov detectors deployed across the moors were connected by underground cables and transmitted information to the control huts via radio signals in the microwave frequency range. All communication is now severed. Cut cables coil in rain filled tanks. The cosmic rays are still pounding down upon these new unwatched ecosystems but the detectors have moved elsewhere.

I am looking forward to meeting Professor Alan Watson FRS here in the autumn. He is eminent in the field of cosmic rays and helped initiate the extensive air shower project, working at Haverah Park for 25 years. He has kindly agreed to meet and share his insider knowledge of the history and operations at the site.

The idea to build a truly giant shower array was launched by Alan Watson and Jim Cronin shortly after Haverah Park was decommissioned and thanks to the ground breaking work undertaken in these huts, it evolved to become the vast Pierre Auger Observatory in Argentina, named in honour of the man who first discovered extensive air showers.

Peering into the darkness, trying to fathom the structures of the universe or what’s inside the hut, and the nature of that relationship.

The ultra high energy particles detected at Havarah Park and new arrays across the globe are very rare, possibly less than one per square kilometre per century, so it is big news when one arrives. Because they have such high energy, it is thought they shouldn’t be affected by galactic magnetic fields, and therefore, the direction of the particle could be determined and the source located. The Amaterasu particle, named after the sun goddess in Japanese mythology, the second most powerful particle to be recorded, appears to have emerged from the Local Void, ana area with no astronomical objects that might produce such a particle. There is no explanation of where these particles come from, just hints of bigger mysteries to unfold.

Many water tanks remain around Haverah Park, stripped of their purpose as water Cherenkov detectors they now reflect the sky in the rainfall they collect rather than record showers of particles from space.

During operation, huts were built in groups of three, each with six large galvanised steel tanks lined with white plastic to diffuse the light and filled with local purified water. Each tank was monitored by extremely sensitive photon detectors which recorded the Cherenkov light emitted as particles passed through the water. At the end of the large array experiment, one of the detectors was opened, and the water was found to be crystal clear and good enough to drink. The proof that water could be kept bacteria-free in a sealed container for over 25 years gave confidence in using the same technology for a future larger cosmic ray detector array to be developed.

Haverah Park was once one of the largest extensive air shower arrays in the world, with an area of 12 km2, but in the end, it just wasn’t big enough.

When Alan Watson and Jim Cronin proposed building a new 3000 km2 shower array, the question from funders was, ‘why do you want to make the array so large?’. The answer is, of course, to discover those known and unknown unknowns, but funders don’t usually like unpredictable outcomes. Luckily their plea was bolstered by the Fly’s Eye Cosmic Ray Detector Array out in the Utah Desert recording the Oh-My-God particle in 1991, it’s energy was 40 million times greater than that of any particles ever produced in any terrestrial particle accelerator. This and other evidence of extremely high energy particles sparked interest in the field of astrophysics and validated the discovery of similar particles at Haverah Park, which had not been taken seriously at the time. This ambitious proposal gained momentum during the 1990s to become the Pierre Auger Observatory in Argentina, with the detector design developed from the water Cherenkov tanks so successfully operated at Haverah Park. The huts here may be in ruins, but their legacy lives on at the world’s largest extensive air shower detector array, which is edging closer to answer the question ‘Where do ultra-high-energy cosmic rays come from?’

I am looking forward to developing work responding to the legacy of the Haverah Park experiment and building on my experience of creating The Absolute Hut (of absolute potential) New surfaces to explore, more moss, and also lichens here.

‘The Belly of a Rock’ video has waited a long time for its crusted shell. A hybrid between rock, mollusc, and technology inspired by the chemical conversations and urge to create described by Italo Calvino in his story ‘The Spiral’. We don’t always know what we are creating. Within ‘the belly’ surfaces slide and scrape along lines of fissure, distended innards ooze and rocks moan as they are distorted by untold pressure. The turbulent spiralling of the core births rock and lifeforms acted upon by the drag of the oscillating magnetic field.  

I have acquired a large number of photochromic optical lenses. These I have sorted by diameter, thickness and distortion. Initial thoughts about their use include using them as petri dishes to grow crystals which are embedded into small concrete hexagonal pillars of differing heights with reference to the geology of giants causeway. Using them to create composite windows into a new hut structure filled with video projections referencing the fly’s eye cosmic detector array.

A good workout on the guillotine making 201 cuts in copper sheet in preparation for a new concrete tablet in the Instruments of the Anemoi sculpture series.

Beverley Duckworth’s installation Surplus at Goldsmiths MFA final show. Beverley’s work is grown through a diligent process of care. Found materials are literally given new life in the seeds which are embedded into them, which then transform and colour them. The installation includes an intermittent sound element of recordings of the melody played by waste trucks in Taiwan to call people to bring out their rubbish.

Apparently I wasn’t the first person to be struck by similarities to the landscape of Yangshuo near Guilin China. I visited in 1984 and think it is no longer a quiet little village.

It was the first time I had been back inside the Ben Pimlott building at Goldsmiths since by own graduation, a scary twenty years ago. The building was brand new then and the views with little visible green fed into my installation Re:construction – a large screen print with tiny viewing hole to a tiny oasis amidst the grey, albeit a synthetic one.

Yinka Shonibare Suspended States at Serpentine South. Horrors of war and colonialism are filed under dazzling colour, birds on the brink of extinction stare in plea or accusation, beacons of light in the darkness come from miniature replicas of sanctuaries.

Yinka’s socially engaged inclusive practice spills over into real help for artists and communities. The exhibition celebrates Guest Projects and G.A.S. Foundation in Lagos. Guest Projects is such a generous idea and I have been so lucky to benefit from it with the project Laboratory of Dark Matters

Being awarded a month’s residency at Guest Projects was crucial to the success of Laboratory of Dark Matters as a site for developing ideas and subsequently touring the project. Wonderful to meet Yinka and also to be part of the selection committee for the next round of projects.

Judy Chicago Revelations at Serpentine North. The highlight of this show is the video documenting The Dinner Party (1974-79) installation and the preparatory drawings and sample plate. What a shame the actual installation wasn’t here, I will have to visit the Brooklyn Museum, New York sometime to see it. The research, collaborations, crafts and designs that went into creating it was phenomenal.

Saw Complicité’s excellent Mnemonic at The National Theatre, 25 years after first seeing it at Riverside Studios. ‘A body is found in the ice, and a woman is looking for her father while a man searches for his lost lover. Mnemonic is as much about origins as it is about memory, and remembering what is lost. Mnemonic asks us: what is our place in the natural world? How have human relationships with the environment shaped patterns of migration? Who are we, and where do we come from? ‘

Visited the delightful mellow brick country home and extensive gardens of pioneering naturalist Gilbert White at Selborne. His book ‘The Natural History of Selborne’ (1789) has never been out of print since it was published more than 230 years ago. He was brought to many people’s attention, including mine, during the pandemic and lockdowns of 2020 when writer Melissa Harrison included his diary readings in her podcast The Stubborn Light of Things.
