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 University of the Free State (UFS) became the proud recipient of a copy of a Pasture Science research volume.

The 508-page volume was presented by Prof. Brian Roberts, an adjunct professor at the James Cook University in Cairns, Australia, to the UFS Sasol Library. It consists of 43 papers on his agricultural research work in the Free State from 1956 to 1975.

He said the Faculty of Natural and Agricultural Sciences at the UFS had the power and expertise to lead the way in food security in South Africa and in building a sustainable society. He also stated that not enough people were taking food security seriously.

“Whatever else you regard as priority, none is more basic than support for the nation’s food producers,” he said.

The papers in the bound copy are arranged in two groups. The first section focuses on Pasture Management. “This series forms a useful overview of Pasture Science,” he said.

The section on Grassland Science covers all aspects of the maintenance, improvement and utilisation of veld and cultivated grasslands.

The second part is a series of publications arising from his fieldwork in the Free State, Eastern Cape and Lesotho.

“Having read with great interest the curriculum vitae of the Vice-Chancellor of the UFS, I felt a strong inclination to contribute somehow to the transformation process and the emerging future UFS,” said Prof Roberts.

Although he acknowledged that change could not happen overnight he was, however, positive that medium-term results could be achieved in that regard.

“One way of doing this is to focus staff and students’ attention on working towards a sustainable society, an on-going curriculum challenge which should, at an early date, replace the past preoccupation with race – an issue that has dogged progress for too long,” he said.

Prof. Roberts was a foundation lecturer in Pasture Science at the UFS 36 years ago before he left for Australia where he plays a fundamental role in land-use planning.

He is also recognised as the father of Landcare, an Australian partnership between the community, government and business to protect and repair the environment.
