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 Council of the University of the Free State (UFS) has approved the appointment of Prof Loyiso Jita as Dean of Education during its quarterly meeting held on the Bloemfontein Campus on 17 November 2017.

“Prof Jita has a strong academic background and a good understanding of the higher-education sector. I look forward to working with him and to realise the vision of the university as a research-led, student-centred and regionally engaged university that contributes to development and social justice through the production of globally competitive graduates and knowledge,” says Prof Francis Petersen, UFS Rector and Vice-Chancellor.

“It is indeed a privilege for me to lead a team of committed teachers and researchers in the faculty, providing excellent service to our undergraduate and postgraduate students. I thank the Council and executive management for their trust in me,” says Prof Jita.

In January 2017, Prof Jita was appointed as the Acting Dean of the Faculty of Education at the UFS. He will assume the position of Dean of the Faculty of Education on 1 December 2017.

Prof Jita began his career as a Science and Mathematics teacher, after graduating from Wits University in 1988. He later took up a lectureship position at the University of Zululand, where he was awarded a Fulbright scholarship to read for a PhD at Michigan State University in the USA. In the mid-1990s, he worked as a policy researcher at the University of KwaZulu-Natal where he, among others, helped to compile the submission on the Violation of Educational Rights of South Africans during apartheid, to the Truth and Reconciliation Commission (TRC).

He joined the University of Pretoria (UP) in 2001, after returning from a post-doctoral fellowship at the Northwestern University in Chicago, and was later appointed Director of the Joint Centre for Science, Mathematics and Technology Education (JCSMTE). He left the UP in 2008 for an appointment as an associate professor at the University of South Africa (Unisa), where he later became the inaugural Director of the School of Education. In 2011, he became a full professor and was appointed as the acting Deputy Executive Dean in the College of Human Sciences at Unisa.

In 2012, he joined the UFS as Research Professor in the School of Mathematics, Natural Sciences, and Technology Education. In November 2014, he was appointed as the SANRAL Chair for Science and Mathematics Education. Professor Jita has published many articles on instructional leadership, teacher development and change, Science and Mathematics education, and has presented over 50 papers at local and international conferences. He has also supervised to completion more than 37 master’s and PhD graduates, and is currently the editor-in-chief for the accredited journal, Perspectives in Education (PIE).
