I am thrilled to have work included in Cosmos: The Art of Observing Space curated by Ione Parkin showing at the Royal West of England Academy, Bristol. Delivered in partnership with the Royal Astronomical Society, this exhibition offers a unique journey through time, imagination, and inquiry – inviting you to experience the awe, wonder, and curiosity that the cosmos continues to inspire.

My works in the exhibition include The Azimuth Obelisk (of Sedimentary Knowledge), a reimagining of an obelisk operating as a permanent azimuth mark, from which the drift of the magnetic North Pole is monitored; Orbital a multiscreen installation looking at the interaction between space weather and Earth’s magnetic field; 92 Years Measured in Lighta reflection on time spent on Earth in relation to the vastness of the cosmos and Sun Factora look at sun worship and a reminder of the Sun’s true power.

Install in progress.

I enjoyed a site visit to Brompton Cemetery Chapel on a bright frosty morning with curator Catherine Li to plan a future exhibition at this magnificent Grade II listed building. Entering the glass domed chapel is entering a space both hushed and echoing. Concentric circles in varying shades of bath stone span the floor circled by eight giant Corinthian columns. Built in 1842 the eight-sided building is said to represent life on earth, while its lofty dome suggests heaven. Early ideas for the exhibition are thinking about ‘way finding’ in terms of physical and spiritual navigation to find a path or direction.

Brompton Cemetery offers a rich site for discovery of the many symbols used to represent the passage from life to death, to comfort, grieve and express love. I was particularly taken by the beautiful sun dial with the inscription YET A LITTLE WHILE IS THE LIGHT WITH YOU

Lessons in electrons.

I listened to an archive episode from In Our Time Pauli’s Exclusion Principle

The Pauli Exclusion Principle proposes that no two electrons in an atom can be in the same configuration at the same time, and it helps explain a wide range of phenomena such as the electron shell structure of atoms. This principle explains the chemical behaviour of the elements and why matter is stable. At the beginning of the 19th century the elements were ordered in the periodic table by mass and it was noted that inert elements appeared very regularly in the table with active elements either side – a periodic occurrence of common properties, hence the name. It was found that if you heated the elements, each element emitted light of a specific colour which became known as the spectra.

The internal workings of the atom were discovered to consist of negatively charged electrons whirling around a positively charged nucleus but the metaphor of a miniature solar system based on gravity was inaccurate. It is hard to get away from imagining this image. It was Niels Bohr who realised that electrons were not free to travel anywhere but are restricted to ‘orbits’ – a helpful analogy is to think in terms of a ladder where an electron can be on a high rung with high energy or a low rung with low energy but can’t be between rungs. Electrons can jump from a high rung to a low rung and in so doing lose energy as light in a characteristic colour.

Pauli, a theoretical physicist, discovered that electrons cannot move to a place where there is already an electron and this is what gives rise to structure and the different chemical natures of the atoms. The different rungs on the ladder have different shapes and can accommodate different numbers of electrons. The bottom rung can only fit two electrons, if the rung has just 1 electron it is hydrogen, if it has 2 electrons it is helium and that rung is then full. Helium is chemically inert because that low rung is now full. The next rung up can hold about 10 electrons and when that is full that element is inert. Pauli also noticed that it was possible for electrons to have two values but couldn’t explain this – we now know this as spin – the electron can spin in different directions.

Photons do not have an exclusion principle, you can add more and more photons and make laser beams as intense as you like. I always wondered about Vantablack (the world’s blackest man-made substance, a coating of vertically aligned carbon nanotubes that absorbs up to 99.965% of visible light) and if it absorbs so much light where does it go and does the material get hot.

It’s nearly 10 years since the Laboratory of Dark Matters project when, thanks to astrophysicist Dr Cham Ghag and lab director Prof. Sean Paling, I was able to visit Boulby Underground Laboratory to meet scientists looking for dark matter over 1km underground on the N.E coast of England. Dark matter has still not been detected but is still thought to be some sort of particle. Direct detection methods have moved on from trying to detect a direct hit from a dark matter particle with an atom nucleus to looking for signs of electrons scattering from the target.

A surprise Christmas gift was a Van Der Graaf Generator which demonstrates ‘static’ electricity. Considering how the electrons caught up by the generator are rushing about desperately trying to get back to the earth it doesn’t sound very static. Electric current is simply electrons on the move. I’m not expecting quite such dramatic results as achieved by this 43-foot-tall experimental high-voltage Van de Graaff generator built at Round Hill, Massachusetts in 1933 as the world’s most powerful particle accelerator, but looking forward to trying some of the experiments.

In February 2023, the highest energy (around 220 million billion electron volts) neutrino ever detected (KM3-230213A) was spotted by the Cubic Kilometre Neutrino Telescope detector, a network of vertical strings with glass spheres holding sensitive Cherenkov radiation light detectors, submerged at great depths in the Mediterranean Sea. This neutrino had over 100 times higher energy than any other previously detected and its origin is still under investigation. High energy neutrinos travel in straight lines, unaffected by galactic magnetic fields, and so could point directly to their violent birthplace, offering insight into the universe’s most energetic processes. It may have been a cosmogenic neutrino, generated when powerful cosmic rays from deep space smash into gas clouds or photons in the interstellar medium creating these rare elusive particles, or from the universe’s most energetic phenomena, involving immense gravity, density, or explosive power, primarily driven by compact objects like black holes and neutron stars, or even decaying dark matter particles.

AI is not like us; the only way we can have a relationship with it, is for us to become like it.

I thought the ideas presented in the Gresham Lecture Becoming AI – Your Journey to Assimilation? gave a prescient perspective – we are so often focused on AI being trained or designed to be more like humans but are losing sight of the fact that it is we humans that are becoming more like AI, it is us that are changing how we communicate to adapt to the methods of the machine.

While thinking about minerals in clay and how pottery and bricks preserve the direction of the magnetic field in their minerals during the process of firing which heats and then cools the clay – the same process that occurs in a lava flow. Iron-bearing minerals (like magnetite) in clay become “magnetic” when heated in a kiln. As the pottery cools, these minerals lock into the Earth’s magnetic field direction and strength at that time.  I came across Rescued Clay, who transform discarded clay from construction sites into new narratives. Together with local communities, they shape this once-forgotten earth into objects, artworks, and spaces that preserve the memory of land, culture, and people, turning waste into stories worth keeping.

I was fascinated to read about the oldest rock found on Earth in Marcia Bjorerud’s little Geopedia compendium. The Acasta Gneiss complex dates from 4.03 billion years ago, any rock that formed on Earth before this time has been melted, obliterated or subducted through violent geologic and astral events save for a few tiny crystals of zircon. The first geologic interval on Earth has left no record. The age of the Earth is therefore determined by looking at the composition of meteorites and planets in the solar system that formed at the same time as Earth and have remained unchanged since. I find this mind blowing.

Out and About

Objects that slip Between the Floor and the Wall at Thames-side Studios Gallery. Some playful works and I particularly enjoyed Eleanor Bedlow’s Push Pull that embodies that idea so well, Jane Millar’s impossibly spikey ceramics with the most gorgeous glazes, the skewed geometrics of Johanna Bolton, morphing oversized beads of Janet Currier and mad Mountain View of Sandra Lane.

Noémie Goudal The Story of Fixity, an Artangel commission at Borough Yards. Three large screens layered with cut out shapes, that add a 3D staging to the film projections which cycle every 15 minutes through lush vegetation, whiting out to fading painted backdrops and water cascading in rivulets or vaporous spray and dark rocks. Water also drips from the ceiling pooling and staining large steel plates on the floor. The sound is layered like a deep forest. Haunting and beautifully captivating.

Prof. Mike Lockwood gave a talk at the Royal Astronomical Society on Aurora borealis observations over the past 400 years in part inspired by the events of 10/11th May 2024 when the aurora was seen by many people across the UK at extremely low latitudes. It is estimated that this aurora in May 2024 was the third most extensive seen in the past 400 years.

Earth’s magnetic field is constantly moving and this has a major effect on where aurorae occur.

It is thought the vision of Ezekiel in the old testament was possibly a red coronal aurora seen in Nippur (Iraq) as it tallies with Assyrian and Babylonian documents which date it at 12th March 567BCE.

In 1741, Clockmaker and geophysicist, George Graham witnessed the aurora in London and made the connection between the lights and geomagnetic activity which he was able to measure with his almost friction free compass needle that he had invented in 1701.

He noted ‘Who could have thought it? That a compass needle could have sympathy and a connection with the aurora!’.

The 1859 Carrington Event was the strongest recorded geomagnetic storm in history, caused by an unusually strong solar flare. The simultaneous observation of the solar flare by the English astronomers Richard Carrington and Richard Hodgson and the subsequent geomagnetic disturbance led scientists to realize the Sun could directly affect Earth’s magnetic field, a pivotal moment in the study of space weather. 

On 7/8th March 1918 the UK skies were lit up to devastating effect as the auroral light reflected along the path of the river Thames giving German bombers a map to the otherwise darkened city of London.

With the advent of the digital camera aurora recording has become ubiquitous across social media. It appears the phone camera can ‘see’ a much brighter and more vibrant effect than the human eye. This is because it can take at least 30 minutes for the human eye to become fully adapted to the dark and sensitive enough to compete with the camera. Looking at the phone will also negate any sensitivity of the eye. Human night vision has evolved to be in black and white, the cones that create colour do not fire unless the light is very bright and so the aurora is often experienced as white pillars without the greens and reds we see on the camera.

The European Space Agency has simulated a solar storm on the scale of the Carrington Event, the most powerful in recorded history. The simulation shows that in minutes, communications were disrupted and in hours, satellites destabilized. There’s no way to stop it, but early warning systems and space weather monitoring could help us prepare.

Scientists Warn: A Solar Superstorm Could Hit Earth Any Day

I am excited to be planning a visit to Haverah Park, the site of a cosmic ray air shower detection array consisting of water Cherenkov detectors distributed over an area of 12 km2 on the Pennine moorland, North Yorkshire. The experiment was operated by University of Leeds for 20 years, and was switched off in 1987. During its lifetime many 1000’s of extensive air showers were recorded including four exceptional ones of such size that the cosmic rays that generated them must have had energies greater than 10eV. These particles are the highest energy form of radiation known to exist anywhere in the universe and their origin is one of science’s greatest mysteries. Having reimagined The Absolute Hut seen at Hartland Magnetic Observatory for the exhibition A Stone Sky I am hoping a future project may be the reimagining of the huts from Haverah Park.

The exhibition Carbon: under pressure at Science Gallery Bengaluru is still running and I am so proud to have my work Cosmic Chiasmus: crossing the universe included in this amazing show. This video 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 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.

I am fascinated to learn more about cosmic magnetism and its influence on the development of early life.

The Universe is magnetic. From stars to galaxies to intergalactic space, magnetic fields thread the cosmos. Yet the origin of cosmic magnetism is still unknown, so astronomers are attempting to make maps of the magnetic fields inside massive galaxy clusters to determine if cosmic magnetism came from the early origin of the universe or developed over time. If it is discovered that there is an alignment of fields across the universe this would point to a primordial source of the cosmic magnetic structure rather than a slow emergence from seed magnetic fields. Understanding the origin of cosmic magnetism may give clues to the development of life on Earth and the possibility of life elsewhere in the universe. Only planets with a magnetic field have an atmosphere and offer protection from most radioactive cosmic rays.

Those cosmic rays that do penetrate the atmosphere may have influenced the development of early life. Chirality, also known as handedness, is the existence of mirror-image versions of molecules. Like the left and right hand, two chiral forms of a single molecule reflect each other in shape but don’t line up if stacked. All known life-forms show specific chiral properties in chemical structures as well as macroscopic anatomy, development and behaviour. The sugars that make up DNA, for example, are all right-handed. The amino acids that make up proteins are all left-handed. It is not clear how this asymmetry evolved but one theory suggests that magnetic surfaces on minerals in bodies of water on the primordial Earth, charged by the planet’s magnetic field, could have served as “chiral agents” that attracted some forms of molecules more than others, kicking off a process that amplified the chirality of biological molecules.

Another theory proposes that the influence of cosmic rays on early life may explain nature’s preference for a uniform “handedness” among biology’s critical molecules. Before life emerged on Earth, self-replicating molecules were slowly evolving beneath a constant shower of energetic particles from space. Researchers believe that cosmic rays with the ability to penetrate matter were potentially colliding with chiral molecules on Earth and everywhere else in the universe. These tiny differences in the mutation rate would have been most significant when life was beginning and the molecules involved were very simple and more fragile. Under these circumstances, the small but persistent chiral influence from cosmic rays could have, over billions of generations of evolution, produced the single biological handedness we see today.

Chirality is also seen in the spiral of a mollusc shell. I am in the process of finishing the sculpture shell for belly of a rock a hybrid work of chemical conversations at the intersection of the animate and inanimate, inspired by Italo Calvino’s Cosmicomics story The Spiral. Paper clay with crushed mussel shells.

My most recent video installation Orbital shown in Life Boat at APT Gallery focused on the potential risks to technology and life on Earth from extreme solar storms.

The following month, a barrage of large solar flares and coronal mass ejections jettisoning clouds of charged particles and magnetic fields, travelling at speeds up to 3 million mph toward Earth, created the strongest solar storm to reach Earth in two decades, and possibly one of the strongest displays of auroras on record in the past 500 years. There were even perfectly clear skies to view this extraordinary event, yet I missed it. So envious of all those who did get to see the displays of Aurora at such low latitudes. I am hoping there will be another chance to see the Aurora in the UK during this current year of peak solar activity, but not so dramatic a storm as to cause an ‘internet apocalypse’.

Gallery Visits

Andrea V. Wright Eyes of Skin at Thames-side Studios Gallery curated by Thorp Stavri. This exhibition explores the permeability and interactions between the body and architecture and the tensions arising from the ever-changing precariousness of our external and internal constructed environments. It was good to be able to chat with Andrea about her influences from fashion tribes and processes such as casting skins from buildings tumbling into ruins and tactics to avoid being vulnerable working in remote locations.

Holly Birtles and Charly Blackburn in Bog Bodies at APT Gallery. interrogate the complexities of wetland mysteries in the Thames Estuary and the Fenland Marshes exploring life, death, and metamorphosis through ceramics and photography. The Bog preserves the body in death enabling us to travel back in time as far as the Mesolithic period. Conditions inside the bog are acidic. They are perpetually wet, entangled with plants and peat, muddy and monstrous. A dense soup inhabited by complex ecologies that thrive in the anaerobic surroundings, creating a unique biochemical and physical occurrence that facilitates the mummification of prehistoric humans. This exhibition however, confounds expectations of oozing mud and swampy detritus. These ‘artefacts’ are presented in a pristine white cube setting, there maybe a slight whiff of smoke lingering from the ceramics but all is clean and orderly and the framing is thoughtful with a nice use of colour contrasts between image and frame. Good to be surprised.

SALON FOR A SPECULATIVE FUTURE: HOW TO BE IN THE FUTURE? at Vestry St – Cross Lane Projects with works from Aideen Barry, Quilla Constance, Lisa Chang Lee, Kate Fahey, Young In Hong, Evy Jokhova, Huma Mulji, Koushna Navabi, Monika Oechsler, Rebecca Scott, Jo Stockham. Postulating hope for a better future Rebecca Solnit (in an article in the Guardian, 2016): wrote “Hope is an embrace of the unknown”. Living in times of unprecedented change, uncertainty, she says, has “the power to influence the future”. Taking inspiration from the ‘future thinking’ of speculative fiction and looking at a wide range of fields from science and technology to spiritual, ecological and socio-economic issues, the exhibition highlights multiplicities and the complex interplay at work in global dynamics. The works, individually and collectively, draw on associations from different  subjectivities and contested /histories facilitating a space for contemplation and the discussion of positive futures. Strong shift shaping work here that gets under the skin, fake facades, hairy hissing and an AI doctored doctrine, make for an unsettling present from which to speculate on the future.

The Tipping Point at Bell House. The tipping point may arrive seemingly out of the blue as a slight change heralding a new way forward.  It can be magical or malevolent.  More than 40 artists in six individually curated spaces will examine different kinds of tipping points, both minor and major, literal and metaphorical. Sarah Sparkes and Jane Millar curate The Gowan Room using Octavia Butler’s dystopian novel, ‘Parable of the Sower’, as a point of reference. Jonathan Callan, Chudamani Clowes, Sarah Doyle, Lydia Julien, Marq Kearey, David Leapman, Yair Meshoulam, Jane Millar, Stephen Nelson, Victoria Rance, Alke Schmidt, Lex Shute, Ania Tomaszewska-Nelson, Sarah Sparkes, Sara Trillo, Marianne Walker and Alice Wilson explore a new awareness of change and exchange, a constant shifting of strange identities, the malleability of being, interspecies communication and the strength and vulnerability of community. Imagining new ways to merge; ways to intelligently and sensually live in the flux of a perpetual tipping point. Léonie Cronin curates the Lutyens room as a procession through objects of different artistic beliefs, pointing to new myths, a point of Syncretism where ideas become merged and the old symbols get incorporated into new systems.

Thomas Pausz in Haunted Ecologies at Stanley Picker Gallery. A very interesting show drawing threads of local history together with current urgencies such as sewage pollution of the local endangered chalk stream Hogsmill River. From spirit photography and the dark room experiments of Kingston’s Eadweard Muybridge, to digital manipulation, rendering and 3D scanning – Our perception of contemporary environment and culture is always haunted by spectres of the past and by hopes and visions of the future.

Symbiosis II group exhibition exploring the relationship between image makers, the more-than-human, and alternative photographic processes at Four Corners Gallery organised by London Alternative Photography Collective  curated by Hayley Harrison, Melanie King, and Ky Lewis. This exhibition considers the connections between symbiosis and alternative photography, and asks if nature is a collaborator or a commodity in alternative photography processes.

YOKO ONO: MUSIC OF THE MIND at Tate Modern. The main takeaway from this extensive overview of her pioneering work is the sadness that peace hasn’t been given a chance. The works are very direct, may appear simple in content or execution but cut deep into the human psyche. I particularly liked Half a Room, first presented in 1967, this is a room of objects cut in half and painted white. Ono said of this work “Molecules are always at the verge of half disappearing and half emerging…somebody said I should put half a person in the show. But we are halves already.” Another piece, Helmets (pieces of sky) from 2001 invites the audience to take a piece of the sky, which she sees as a hopeful symbol of limitless imagination. Jigsaw pieces of the sky are suspended in German army helmets, and although dispersed, offer the possibility of hope that they can be put back together through collective healing. Many works are participatory. A wall for drawing around your own shadow to create an entanglement of bodies. A boat to add your own wish to an ocean of wishes for the future.

Geographies of Print final iteration of Without Horizon, Without Shore at Thames-side Studios Gallery. Geographies of Print is a collective group created by artists Victoria Ahrens, Carol Wyss and Victoria Arney in 2020. This collective looks to explore and challenge notions of print within wider contemporary discourse and practice. The artists fully inhabit the given space with dramatic large scale pieces, that interact and collaborate to create an exciting and cohesive exhibition. Blocks of colour flash between a maze of hanging muslin panels where etchings of impenetrable blacks and misleading undulations recall both mountain paths and the shadowy mazes of ancient cities. Emotive live music improvisation by Jim Howard (trumpet and electronics) and Julie Walkington (bass) accompanied Victoria Arney’s film reflecting on the epic journey of migrating birds. Landscapes of the mind and the body, a birds eye view and the internal geology of the Earth are beautifully explored.
