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.

Archbishop Emeritus Desmond Tutu visiting the UFS once again

2012-07-13

Archbishop Emeritus Desmond Tutu
13 July 2012

The University of the Free State (UFS) will once again be honoured by the presence of Archbishop Emeritus Desmond Tutu on Wednesday 18 July 2012.

Dr Tutu will be speaking at our Bloemfontein Campus for the first session of a two-day “In Conversation With …”event that is part of the Global Leadership Summit currently being held on the campus.

This sessions starts at 09:30 at the Centenary Complex. The media is invited to attend this session.

Dr Tutu will be in dialogue with Prof. Mark Solms, Head of the Department of Psychology at the University of Cape Town and owner of the Solms-Delta Wine Estate in Franschhoek.

The theme for this conversation, facilitated by Prof. Pumla Gobodo-Madikizela, will be “Living Reconciliation: Winds of Change in Franschhoek and Transformation at Solms-Delta Wine Estate”. This is based on the transformation introduced by Solms on his farm in the Franschhoek Valley.

Prof. Gobodo-Madikizela is a Senior Research Professor on trauma, forgiveness and reconciliation at the UFS.

As owner of Solms-Delta Wine Estate in Franschhoek, Prof. Solms led an initiative to transform the lives of farm workers on the estate through the Wijn de Caab Trust. This initiative was extended to empower the wider community of farm dwellers when Prof. Solms co-founded the Delta Trust and the Franschhoek Valley Transformation Charter. This organisation aims to break trans-generational cycles of social division and inequality in the valley.

The dialogue with Dr Tutu will highlight the significance of these initiatives as examples of deepening the link between socially responsive scholarship, commitment to social justice and responsible citizenship in contemporary South Africa.

Last year, the UFS awarded Dr Tutu an honorary doctorate in Theology, marking a milestone in the history of the university.

At 12:30, Dr Tutu will visit the Red Square in front of the UFS Main Building, where he will join in the fundraising festivities for the university’s official Nelson Mandela Day event and deliver a short address.

Schools in the vicinity, UFS staff and students and the public are invited to take part in the R5 coin laying ceremony in front of the Main Building.

The money collected at this event will be used to benefit the No Student Hungry (NSH) campaign as well as Bloemfontein Child Welfare.
