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 King’s Singers, the acclaimed British a cappella vocal ensemble, are coming to Bloemfontein, hosted by the Odeion School of Music at the University of the Free State, for an unmissable performance.

Concertgoers from Bloemfontein and surrounding areas have the opportunity to experience this extraordinary vocal ensemble at the Dutch Reformed Church Universitas at a concert sponsored by the Arts Trust.

Named after King’s College in Cambridge, the group was formed in 1965, and for the past 48 years, their work, synonymous with the very best in vocal ensemble performance, appeals to a vast international audience.

The ensemble has performed for hundreds of thousands of people each season, and regularly tours Europe, North and South America, Asia and Australasia. Instantly recognisable for their immaculate intonation, vocal blend, diction and incisive timing, the King’s Singers are consummate entertainers.

The group’s repertoire has evolved to become one of the most diverse and compelling imaginable. They have commissioned more than 200 works, including landmark pieces from leading contemporary composers including Luciano Berio, György Ligeti, Sir James MacMillan, Krzysztof Penderecki, Toru Takemitsu, Sir John Tavener, Gabriela Lena Frank and Eric Whitacre. They have also commissioned arrangements of everything from jazz standards to pop chart hits, explored medieval motets and Renaissance madrigals, and encouraged young composers to write new scores.

In addition to performing to capacity audiences and creating highly regarded and much-loved recordings, the King’s Singers share their artistry at numerous workshops and masterclasses around the world.  

Double Grammy award-winning artists, the group were honoured in 2009 for their Signum Classics release, Simple Gifts, and again in 2012 for their contribution to Eric Whitacre’s Light and Gold album. Recently voted into Gramophone Hall of Fame, rave reviews and repeated sell-out concerts confirm that the King’s Singers are one of the world’s finest vocal ensembles.
