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 journey does not belong to him alone, but to everyone at KovsieSport.

These were the words of University of the Free State’s (UFS) Wayde van Niekerk, after being named as KovsieSport’s Senior Sportsman of the Year on Wednesday 21 October 2015.

The South African sports star walked away with the award for the third consecutive year, while the Protea netball defender, Karla Mostert, was crowned Senior Sportswoman for the first time.

The Junior Bok, Ox Nche, and the Protea hockey player, Nicole Walraven, were named as Junior Sportsman and Junior Sportswoman of the Year respectively.

Nche represented South Africa’s U20 rugby team this year at the Junior World Championships, played for the Shimlas, and was named the UFS Rugby Club’s best junior player.

Walraven made her debut for South Africa in 2015. She was crowned jointly as the best player at the Provincial U21 tournament, and was also Hockey South Africa’s U21 Player of the Year.

Van Niekerk won gold in the 400 metres at the World Championships in Beijing, becoming only the fourth athlete in history to run the 400 m in less than 44 seconds, and the 200 metres in less than 20 seconds.

“This is precious, and something I will cherish as an athlete: being part of KovsieSport,” he said.

“I arrived at the UFS as a high school boy, started as a junior, and was accepted immediately.”

“I really appreciate everybody who played such a huge part in my life.”

Mostert was named as Player of the Series in the Brutal Fruit series, as well as the Varsity series this year. She was also a star for the Proteas at the World Cup.

“This (the award) is definitely a good way to end my time at Kovsies. This is something one is trying to achieve for years, so it really is a highlight.”

She said it was difficult to describe how much KovsieSport is doing for its athletes, and this was the reason why the UFS achieves so many successes in sport.
