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.

Master’s student awarded Mandela Rhodes scholarship

Candice Thikeson was recently selected as the only 2016 Mandela Rhodes Scholar from the University of the Free State. She is one of 50 young African postgraduate students, eager to contribute positively to the educational development of the continent.

The Mandela Rhodes scholarship is a fully-funded postgraduate scholarship awarded to promising future leaders by the Mandela Rhodes Foundation. It is named after the former president of our country, Nelson Mandela, and Cecil Rhodes, who was known for his business skills and political influence in South Africa. Instituted in 1999, the scholarship aims to advance scholars who demonstrate the principles of Leadership and Reconciliation embodied by Mandela and Rhodes’s legacy, as they relate specifically to Education and Entrepreneurship.

Thikeson expects the programme will educate her on how to integrate the four pillars in relation to her field of study.

For Thikeson, earning the scholarship served as an endorsement of her dream of becoming an academic. “I want to obtain a PhD, lecture at a university, publish papers, and speak at conferences,” she related. “I also want to produce academics, I want to mentor young people,” she added.

Her academic journey began in 2011 when she pursued a BA Fine Arts degree for a year. Thikeson then transferred to a BA General degree which she completed over two instead of the standard three years. She went on to study an Honours degree in Art History and Visual Culture Studies. In the same year, she travelled to Rijksuniversiteit Groningen (University of Groningen) in the Netherlands as part of an exchange agreement between the university and the UFS, where she completed her mini-dissertation in four months. Both her BA and Honours were passed with distinction. Currently, Thikeson is pursuing a Masters degree at the Department of Art History and Image Studies under the supervision of Prof Suzanne Human.

Some accolades to her name include the Jan Teurlinckx Prize for the best student in Art History (2011), the David Jacobs Prize, awarded to the best student in Philosophy (2013), and the Richard Miles Prize, presented by the Dean of the Faculty of the Humanities (2013). Thikeson was also selected as a member of the Golden Key Honour society in 2012, for her consistent academic excellence.

Last year, Lehlohonolo Mofokeng, Zola Valashiya, and Tumelo Morobane made the UFS proud by graduating as the class of 2015 Mandela Rhodes Scholars.
