DR FABIO SILVA, a lecturer in the Sophia Centre at the University of Wales Trinity Saint David’s Lampeter campus, and Dr Daniel Brown, an astronomy lecturer at Nottingham Trent University, have caused a world-wide media sensation with their theory on the use of prehistoric tombs as ‘telescopes’.
After examining 6,000 year old passage graves in Portugal, Silva concluded they functioned like telescopes without a lens.
Viewers within the tunnels would have had a chance to spot the first appearance of Aldebaran, the red star that is the brightest object in the constellation of Taurus before those outside. This was crucial for the rituals which timed seasonal migrations, such as taking sheep to higher pastures. The annual event, Silva argues, could have coincided with the star’s first appearance in the morning twilight each year. “This first rising of Aldebaran occurred at the end of April or beginning of May 6,000 years ago, so it would be a very good, very precise calendrical marker for the move to higher ground,” he said.
“The key thing is that a passage grave with its long corridor acts like a telescope that does not have a lens – it is similar to a long tube that restricts views to the sky close to the horizon.” Dr Daniel Brown added: “Seeing only a small portion of the sky while in a dark environment could help the eye fixate and prolong dark adaptation.”
These astronomical observations could have been linked to ancient rituals in which individuals were left on their own in the tomb with the remains of their ancestors. “There is a wealth of evidence now that these passage graves were not only used as tombs for burials, but they could also be used for rites of passage,” said Dr Silva. Such rituals, he adds, often involve the revelation of an astronomical secret to the initiate. “Could the secret be that the initiate could see the star rising days, if not a full week, before everybody else that was outside the passage grave could see it?” he said.
Dr Silva and the team are currently testing these ideas by simulating the conditions of celestial visibility from within the passage graves in the laboratory.
Dr Silva and the team‘s work was presented at the Royal Astronomical Society’s National Astronomy Meeting 2016 at a dedicated cultural astronomy session coordinated by Dr Brown. It was reported in the UK in The Guardian, The Daily Telegraph, New Scientist and Astronomy Now, and around the world on the BBC World Service; Der Spiegel (Germany); Archaeology magazine, WIRED magazine, CBS News, FOX News and The Washington Post (USA); New Zealand Herald (NZ); The Hindu (India); Jibada (China); and Globo (Brazil).
Dr Silva teaches the course on Skyscapes, Cosmology and Archaeology in the University’s Sophia Centre for the Study of Cosmology in Culture.
Changes to bus services in Ceredigion confirmed by local authority
THERE will be changes to local bus services in Ceredigion from Tuesday 3 January 2023.
The tenders received as part of a procurement process for operating several services have shown significant cost increases. This has resulted in substantial increases in subsidy levels being requested at a time when public finances are under tremendous pressure. The higher costs are largely reflective of particular challenges affecting the bus industry currently which includes considerable increased operating costs, lack of qualified and available drivers, uncertainty around future funding mechanisms as well as declining passenger numbers and changing travel behaviours.
Bus passenger numbers have been in decline across Wales and essentially halved in the period between 1982, where there were 181 million passenger journeys and 2019/20 where there were 91 million passenger journeys. This has been severely compounded by the Covid-19 pandemic, which saw a drop to 26 million passenger journeys in 2020/21, that has further impacted on the viability of local bus services.
The 22T (Aberystwyth-Devil’s Bridge), 27T (Penrhyncoch-Penbontrhydybeddau) and T29 (Tregaron Circular) demand responsive services will stop at the end of December 2022. This is due to the significant costs associated with providing them and the very low level of usage, which equate to unviable levels of public subsidy per passenger journey.
There will be changes to the timetables on the 525 (Aberystwyth-Ponterwyd), 526 (Aberystwyth-Penrhyncoch) and 585 (Aberystwyth-Tregaron-Lampeter) services. The timetables for these services, subject to submission by the operators and approval by the Traffic Commissioner, are attached. These timetables are based on proposals provided by the local bus operators and reflect what is operationally deliverable with the resources available, in terms of buses and drivers, at this time.
The T21 (Aberystwyth-Llanafan-Tregaron) and 552 Cardi Bach (New Quay-Cardigan) services will continue as currently.
All these contracts have been awarded on a 6 month basis to allow for a wider review.
Councillor Keith Henson, Cabinet Member for Highways and Environmental Services and Carbon Management said: “I would like to thank the local bus companies for their ongoing engagement in what is very challenging operating environment. We continue to work with them and in partnership with the other key stakeholders including the Welsh Government and Transport for Wales, seeking possible solutions and a way forward. Bus services and networks are dynamic and subject to change. Further changes are likely as the reality is that, in addition to the sparsity of resources, the amount of subsidy now required to provide the services is unaffordable, unjustifiable and unsustainable in the current financial climate.”

New Rural Health Economics Professor builds on University healthcare provision
AN ACADEMIC who played a key role in decision-making in the adoption of medicines in NHS Wales and NHS England has been appointed as Professor of Rural Health Economics at Aberystwyth University.
Professor Murray Smith, an expert in the use of economics and statistics to predict outcomes in health and health-related behaviours, joins Aberystwyth Business School.
His recent research has centred on the quality of use of pharmaceutical medicine, with one project exploring the use of an inhaled analgesic for acute pre-hospital trauma pain, and others on topics that have spanned medicine use across a number of chronic disease areas.
After beginning his career in Australia, Professor Smith moved to the United Kingdom in 2007 and has worked at the universities of Aberdeen, Nottingham and Lincoln.
Professor Smith said: “I am delighted to join Aberystwyth Business School. Health economics is a vital subject because it provides methods and tools to help decision makers in the choices they face when trying to deliver high quality healthcare in a modern resource-limited economy.
“I am excited about adding to Aberystwyth Business School’s existing portfolio of expertise in research and to being given the opportunity to continue to use my skills to help the NHS to identify and deliver cost-effective healthcare and services to the people of mid Wales.”
Professor Elizabeth Treasure, Vice-Chancellor of Aberystwyth University said: “It is vital as a society that we continue to innovate in our approaches to healthcare and Aberystwyth University is stepping up to the challenge with the launch of our first ever nursing degrees in September 2022 and through interdisciplinary research into combating diseases, using artificial intelligence to improve patients’ health, and exploring new techniques to improve human health through diet.
“The appointment of Professor Smith demonstrates our continuing commitment to developing and delivering high quality healthcare education and research at Aberystwyth. His expertise will focus on the economic aspects of healthcare, and his teaching and research will benefit our students and beyond.”
Professor Smith’s appointment coincides with the awarding of Honorary Professorships to three executives from Hywel Dda University Health Board, further strengthening Aberystwyth University’s expertise in healthcare as well as building on its partnership with the local health board.
Dr Helen Munro, Consultant in Community Sexual and Reproductive Healthcare at the Board; Dr Leighton Phillips, the Board’s Director of Research, Innovation and University Partnerships, and Huw Thomas, its Director of Finance collectively have decades of expertise in the health sector in the United Kingdom.
Steve Moore, Chief Executive of Hywel Dda University Health Board, added: “On behalf of the Board I would like to offer my warmest congratulations to Helen, Leighton and Huw on their appointment as Honorary Professors at Aberystwyth University. Our partnership with Aberystwyth University continues to go from strength to strength and we look forward to continuing our vital work together in the future.”
Professor Elizabeth Treasure added: “I am delighted to welcome our new Honorary Professors, who together will bring decades of experience to our research and teaching. Their expertise will further contribute to the role we have to play as a University in helping improve healthcare provision for everyone.”
