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.

Elinor Sisulu to present lecture at the UFS
2008-07-30

Human rights activist, Ms Elinor Sisulu, will deliver a Women’s Day lecture, titled: “Voiceless and voteless, fleeing zanuphobia into xenophobia: A Zimbabwean woman’s perspective of National Women’s Day” at the University of the Free State in Bloemfontein on Wednesday next week.
.
She was invited by the Faculty of the Humanities at the UFS to deliver the lecture on Wednesday 6 August because of her stature as an activist and writer and her views on the topical issue of Zimbabwe.

The Vice-Dean of the Faculty of the Humanities, Prof Engela Pretorius, said the UFS was keen to engage the larger community on these kinds of issues and invites all interested people to attend.

Ms Sisulu is a writer, human rights activist and political analyst. Born in Zimbabwe, she was educated in Zimbabwe, Senegal and the Netherlands.

She combines training in history, English literature, development studies and feminist theory. In 1994 she published an award-winning children's book, “The Day Gogo Went to Vote”.

Her biography about her mother-in-law and father-in-law, titled “Walter and Albertina Sisulu: In Our Lifetime”, was published to critical acclaim in December 2002. The book was runner-up in the 2003 Alan Paton Non-fiction Award and won the 2003 Noma Award for publishing in Africa.

Ms Sisulu works in the South African office for the Crisis in Zimbabwe Coalition, the major umbrella body of Zimbabwean non-governmental organisations.

The lecture will start at 19:00 in the CR Swart Auditorium on the main campus in Bloemfontein.

Light refreshments will be served.

Those wishing to attend must please make a booking with Hettie Beukes at 051 401 2240 or beukeshs.hum@ufs.ac.za.
