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 can lead SA in race relations - Ramphele

The University of the Free State (UFS) could well be a perfect model of excellence in race relations that the whole of South Africa could emulate.

This was said by Dr Mamphela Ramphele, the first African to be a Managing Director of the World Bank, during the Anti-Racism Network in Higher Education (ARNHE) Colloquium held at the UFS recently.

“Healing circles need to be constructed on this campus to address issues raised by the Reitz incident,” she said.

“You might yet be the pioneer of what needs to happen on a nation-wide level.

“Can we confidently commit today to go on this quest for a true humanity and walk together as fellow citizens and strive for a more human face for our society? That is our challenge. That is what the UFS is called to give leadership to.”

“It is this human face which has the power to liberate us from the body of death and strengthen us in our struggle for meaningful life together in South Africa,” added one of the main speakers, Dr Allan Boesak, a cleric and former anti-apartheid activist.

However, said Dr Ramphele, this could only be achieved if all South Africans, black and white, abandoned the fear for each other that was hindering, if not stalling, progress in this regard.

“Fear of each other is the most important impediment to the sustainability of our journey into a society united in our diversity,” she said.

“People in this country are afraid to stand up and be counted, including many vice-chancellors and clerics. They are afraid of being seen to be difficult, and that is a major problem. Fear is the most destructive emotion that you can have because it makes you really incompetent and unable to respond to challenges.”

She said the biggest impediment, though, to ending racism was denial. “White people deny vehemently that they are or have ever been racist,” she said.

“We need to go through a process of acknowledging our wounds and scars from our racist past and present missteps in public policy.”

“Instead of saying they are sorry, those who are conscious of their whiteness should rather say what they are sorry for,” said another main speaker, Prof. Dennis Francis, the Dean of the Faculty of Education at the UFS.

On the other hand, according to Dr Boesak, blacks were and still are, to a large extent, also to blame for their own ongoing oppression. “The key here was the acknowledgement of our sheepish timidity, our complicity,” he said.

The Chairperson of ARNHE, Prof. Norman Duncan, had this to say: “If we are to confront and eradicate racism in higher education institutions, we should not do so to create comfort zones for ourselves.”

The theme of this ARNHE Colloquium was Black consciousness and those conscious of their whiteness. It was presented by the International Institute for Studies in Race, Reconciliation and Social Justice at the UFS.
