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.

The Centre for Africa Studies at the University of the Free State (UFS) recently launched its series of seminars commemorating the centenary celebrations of the African National Congress (ANC). The launch of the series took place on 30 November 2010, with the seminar series running from February 2011 until February 2012, the year of the centenary celebrations of the ANC.

Along with UFS staff members and students, various special guests also attended the launch of the seminar series, including former Premier Ms Winkie Direko, representatives of the office of the current Premier and the Vice-Chancellor and Rector of the UFS, Prof. Jonathan Jansen. Prof. Jansen praised the Centre for Africa Studies for its vision in establishing the seminar series and added that he would be a regular attendee when the seminars kicked off in 2011.

The seminar series is the brainchild of Prof. Kwandiwe Kondlo, Head of the Centre for Africa Studies at the UFS. Prof. Kondlo explained that the aims of the seminars were to delve into the legacy of the ANC from a firm historical perspective, as well as to develop a firmer understanding of the dynamics of contemporary South Africa. He stressed the scholarly and academic nature of the seminars, hoping for robust and critical debate amongst future audiences about the topics at hand. Publications in journals and books at the end of the series will be the secondary objective of the Centre.

The three guest lecturers for the launch were Dr Pule Matjoa, Prof. Chris Landsberg and Herbert Maserumule. Dr Matjoa, an ANC veteran, elucidated the history of the party from an insider’s perspective while Prof. Landsberg spoke about the past and present foreign policy of the ANC. Mr Maserumule examined the ruling party’s economic thinking, with special focus on the distinctions between a democratic and developmental state.

The question-and-answer session after the lecture produced lively debate, which set a premise for the rest of the series. The first seminar in the series will take place on 4 February 2011.
