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.

Gaza doctor speaks of hope and courage

In 2009 Israeli forces bombed the house of Palestinian doctor Izzeldin Abuelaish killing four people: three of his daughters and a niece. Speaking about this life-changing event, Dr Abuelaish delivered two public lectures at the University of the Free State (UFS) this week spreading the message of hope and peace.

Dr Abuelaish, who was introduced as the Nelson Mandela of Palestine by Prof. Jonathan Jansen, Vice-Chancellor and Rector, spoke emotionally about the loss of his daughters Bessan, Aya and Miyar. He told the audience that there was no reason for them to be killed. His girls were armed with love, hope and education.

He urged people to have moral courage and encouraged them to strive for justice, truth and peace. When there is justice and truth, peace is a consequence. “As a medical doctor I never lose hope. By the end of this world we will forget what enemies did, but will never forget the silence of brothers.”

Dr Abuelaish spoke passionately about the role of women in society and said a country develops by how much it invests in women’s education. “We must realise the strongest members in a community are women. Women maintain the hope.”

Speaking about his life in the war, being born Palestinian, Dr Abuelaish said it was painful to hear that Palestinians are numbers and statistics. “When a soldier is killed in Iraq or another place, the screen speaks for days about what he ate and what he hoped for, others are figures and numbers.”

Dr Abuelaish, who wrote the book I shall not hate, A Gaza Doctor’s Transformational Journey of loss, Love and Change, said the death of his daughters made him stronger and more focused not to give up. “I swore to my daughters and God not to rest, I fully believe I will meet them one day. I will meet them with the big gift of justice.”
