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.

Dr Oprah Winfrey brought Bloemfontein a warm day in the middle of a bitter cold winter. Outside the Callie Human Centre of our university, people were shivering in temperatures below 10 degrees Celsius.

Inside, however, the audience was engulfed in the excitement and warmth of a very special occasion: media icon and philanthropist Dr Winfrey received an honorary degree in Education from our university.

The graduation was probably the biggest ceremony of its kind in South Africa. The Callie Human was packed with more than 4 500 people who had jumped for the opportunity to attend one of the great milestones in the existence of our university. They had to brave long queues to obtain tickets and to get seated. However, this just added to the excitement of seeing Dr Winfrey in real life.

The ceremony was like a huge reunion or festival. Some people had called in designers to dress them for the occasion, while others fetched their very best clothes from their wardrobes. People tweeted, sent SMS messages, phoned or brought their families with them. Cell phones and cameras captured the occasion.

The graduation ceremony was also an emotional moment for Dr Winfrey, who shed silent tears.

Her motivational talk afterwards was very inspiring. Dr Winfrey said that everybody can be successful. They just need to apply their minds to what they want.

“Never give up. You are not defined by your circumstances. There is hope. Have a vision and let that vision be bigger than yourself. Allow yourself to live in that space of yourself,” Dr Winfrey said.

About 100 volunteers from the univeristy community helped by among others showing guests to their seats, providing guests assistance with parking and taking care of general enquiries from the audience.

The university received messages of congratulations from all over for the arrangements and the professional way in which the ceremony was presented.
