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.

Our university honoured our top athletic achievers at the annual Kovsie Sports Star Awards that took place on 23 October 2014.

Maryka Holtzhausen and Wayde van Niekerk were named Sportswoman and Sportsman of the Year respectively.

Holtzhausen captained the Protea netball team that participated in a host of test series and championships. These included:
•   a test series against Trinidad & Tobago and England in October last year,
•   the Fast Five World Series in Auckland, New Zealand during November 2013, as well as
•   the Commonwealth Games in Glasgow this year.

Van Niekerk, in turn, set a new SA record in the 400 m of 44.38 at the Diamond League meeting in New York, USA during June 2014. As a member of the Protea team who participated in the Commonwealth Games in Glasgow earlier this year, he won the silver medal in the 400 m sprint. In August 2014, Van Niekerk clinched the silver medal in the 400 m at the CAA Senior African Athletics Championship in Morocco. He also formed part of the CAA African Athletics team who competed in the intercontinental cup meeting during September 2014. The team won gold in the 4x400 m relay at this event.

The Junior Sportsperson for 2014 is Driaan Bruwer. He was a member of the SA U/19 cricket team that won the Junior World Cup this year.

Our university’s sports stars were honoured in the following five categories:

•   Sportsman and Sportswoman of the Year. Everyone that represented South Africa at a senior level was eligible for the title. The winners each received a trophy and each sportsman and sportswomen in this category were honoured with a medal.
•   Junior Sportsperson of the Year. The winner received a trophy.
•   Sports stars that represented South Africa at senior and junior level. The achievers received certificates.
•   Sports stars that represented the UFS in the national student teams. These sports stars also received certificates.
•   Certificates were also awarded to the KovsieSport Club sports stars.
