In his book, The World is Flat, Thomas Friedman mentions how at first countries, then companies, and eventually communities went global. In true flat-world fashion, a combined team of the University of the Free State (UFS) and the Astronomical Society of South Africa – led by Prof Matie Hoffman, Associate Professor in the Department of Physics – participated in a once-in-a-lifetime event with their counterparts from the Ellinogermaniki Agogi School and the Skinakas Observatory in Greece.

On 21 December 2020, Earth was treated to the Jupiter-Saturn conjunction, when the two planets were only 0.1 degrees apart in the sky. Although conjunctions are regular phenomena, NASA mentions that the great conjunction of Jupiter and Saturn in 2020 was the closest since 1623 and the closest observable since 1226! A pinkie finger at arm’s length could cover both planets – although they were still millions of kilometres apart in space.

Planning started months ahead of the event, with the Ellinogermaniki Agogi Observatory in Greece and the Boyden Observatory in Bloemfontein chosen as the two selected vantage points. From both the Southern and Northern Hemisphere, the conjunction would be broadcast live on YouTube. As with any other technical project on an international scale, challenges arose. For example, in the Northern Hemisphere, it was already dark at 17:45 while the South African astronomers were still basking in sunlight until after 19:00. The conjunction would only be visible from South Africa after 19:30, almost two hours after it would be visible in Athens. The time was well used, with the event including a word of welcome by the Consul General of Greece in South Africa, Ioannis Chatzantonakis, presentations on Saturn and Jupiter, as well as a virtual tour of the Boyden Observatory, emphasising its connection with Greece through its first Director, Stefanos Paraskevopoulos.

On Saturday, 19 December, the teams ‘gathered’ on opposite sides of planet Earth to do a dry run. One could sense the urgency and tension as both teams realised that they would have a huge captive audience on YouTube, and plans had to be made in case of connectivity challenges and if the weather did not allow the conjunction. As preparations progressed, Prof Hoffman was talking to his Greek counterparts and was simultaneously walking around with his laptop to share the landscape and activities via his webcam with colleagues in Greece.

Monday 21 December 2020 – the weather prediction was correct. Clouds covered the Free State sky and scattered raindrops started to fall. Revert to Plan B. A recording made on Saturday evening was shared via the YouTube link, while a live feed of the conjunction from elsewhere in South Africa was arranged. From both sides of the world, information was shared about the history of the venues, as well as the marvel of what was happening in space. Fortunately, expert planetary photographer Clyde Foster was able to share a live feed just after 19:30 from the observatory at his home in Centurion, Gauteng. Those attending the event where visuals and speakers were together on one screen – yet thousands of kilometres apart – watching an event in outer space, will indeed agree with Thomas Friedman: the world is flat. The live-stream event of the conjunction was a catalyst that will result in continued collaboration between the UFS and colleagues in Greece in the field of astronomy.

By the time of this writing, the livestream has reached more than 50 000 people.

Co-architect of peace and reconciliation in Northern Ireland to present Annual Reconciliation Lecture today

2015-03-03

Colm McGivern, Director of the British Council in South Africa

To emphasise the University of the Free State’s Human Project, the UFS has positioned itself as an institution that is recognised across the world not only for excellence in academic achievement, but also in human reconciliation. The Annual Reconciliation Lecture, whose organising committee is chaired by Prof Pumla Gobodo-Madikizela, is a unique and major initiative to enhance this important vision of our university.

This year, Colm McGivern, Director of the British Council in South Africa, will present the Fourth Annual Reconciliation Lecture at the Centenary Hall on Thursday 5 March 2015.

Colm McGivern was brought up in Northern Ireland at the height of the conflict that has come to be known as the ‘Troubles.’ His early experiences of conflict, sectarianism, and living in a divided society have driven his career, and his personal commitment to peace-building and promoting reconciliation. He was a student leader at Queen’s University in Belfast during the time of the first IRA Ceasefires in the 1990s, and then worked in the Higher and Further Education sectors, and at a community level with peace-building groups across Northern Ireland and internationally. He was Director of the British Council in Northern Ireland for four years and, in that role, facilitated discussions between divided communities before and during the Ceasefires and Peace Process, with a particular focus on bringing young people together across Ireland.

In his role as Director of the British Council, McGivern has created thousands of cultural and educational connections between the UK and SA. Every year, he ensures that young South Africans can get access to educational and cultural opportunities that are life-changing while deepening their connection with the UK.

A highlight of this year’s lecture will be a performance by musicians from the Odeion School of Music, Tumi Ntantiso (soprano), Bertha Menyatso (mezzo-soprano), Malefetsane Mofokeng (baritone), and Cezarre Strydom (piano). They will be performing works from ‘Tales of Hoffmann’ by Jacques Offenbach, among others.

Members of the public and media are welcome.
