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.

UFS honours young researchers

The University of the Free State (UFS) last night honoured 24 young researchers who are taking part in the National Research Fund’s (NRF) Thuthuka programme.

The recognition function is the first of its kind at the UFS. “The renewed focus on research development that was recently announced at the official opening of the UFS by the Rector and Vice-Chancellor, Prof Frederick Fourie, is an indication of the institution’s endeavour to create an environment in which research can be improved and flourish. This can only be obtained when researchers are being valued and that is why it is important to honour our young researchers,” said Mrs Annelize Venter, researcher at the UFS Research Development Directorate and coordinator of the programme.

The focus on research was also touched on recently by President Thabo Mbeki during the opening of Parliament when he said: “We will continue to engage the leadership of our tertiary institutions focused on working with them to meet the nation’s expectations with regard to teaching and research. For its part, the government is determined to increase the resource allocation for research and development and innovation, and increase the pool of young researchers."

According to Mrs Venter, research done in 2004 shows that the majority researchers who publish are white males above the age of 50. “Many students who undertake magister studies choose not to conduct research, but rather to do a thesis and additional subjects. This means that research is not stimulated. Students also find it difficult to obtain financial support for postgraduate studies,” she explained.
“Thutuka is a capacity building programme of the NRF that is aimed to
fund and support the qualifications of women and young black scientists and other researchers who do not have a rating for postgraduate research. It is based on a funding partnership between the UFS and the NRF,” said Mrs Venter.

Last night Prof Frans Swanepoel, Director: Research Development at the UFS, added to his by saying: “With the Thuthuka programme we aim to create and sustain a research culture at the UFS, promote international research and train researchers of a high quality and enhance the research capacity at the UFS by focusing on women, black researchers and other promising researchers.”

The programme was started by the NRF in 2001. At that stage only 17 grants were made countrywide. Last year 370 postgraduate students took part in the programme.

According to Mrs Venter the programme was implemented at the UFS in 2003. “At that stage we only had 5 grant holders. This year there are 24 Ph D and magister students on the programme,” she said.

A couple of young promising researchers, who will be participating in the programme in 2007, also attended last night’s recognition function.

The guest speaker was Prof Jonathan Jansen, Dean: Faculty of Education at the University of Pretoria (UP). He gave tips to young and promising researchers on how to be an outstanding scholar.

Nine professors were also congratulated with their promotion to senior research professor, namely Proff Louise Cilliers (Department of English and Classical Languages), James du Preez (Department of Microbial, Biochemical and Food Biotechnology), Johan Grobbelaar (Department of Plant Sciences), Dingie Janse van Rensburg (Centre for Health Systems Research and Development), Dap Louw (Department of Psychology), Philip Nel (Department of Afro-asiatic Studies and Language Practice and Sign Language), Louis Scott (Department of Plant Sciences), Dirk van den Berg (Department of History of Art) and Andries Raath (Department of Constitutional Law and Philosophy of Law).
