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.

Khayalami residence launches first in-house library

“It is said that reading means to the brain what exercise means to the body. For that reason, we want to bring back the culture of reading to our students who are, after all, the future replacement of the leadership of our wounded and broken country,” said Sinoxolo Gcilitshana, Deputy Residence Head, and Prime of Khayalami.

Titles such as A Life Ever Lasting by Miranda Hearn, To Live Free by William Wilberforce, Powers of Darkness Powers of Light by John Cornwell, and Character Counts by Charles Dyer are among the 228 inspirational books on the shelves of Khayalami residence’s library. Tuesday 12 April 2016 was a proud moment for the residence as it launched the first library in the country located within a university residence on the Bloemfontein Campus of the University of the Free State.

Last year, Dimpho Jasa, a resident at Khayalami, approached Sinoxolo, who then held the Residence Committee (RC): Academics portfolio, with an idea of forming a book club. Sinoxolo had suggested that a library be established in order to make the book club sustainable. That conversation served as a foundation of the 24 hour in-house library.

“We started with five books last year,” said Sinoxolo, “and ever since we sent the message out, the Vice-Chancellor and Rector, Prof Jonathan Jansen has been supporting us together with the Vice-Rector, Prof Nicky Morgan, as well as the Dean of the Faculty of Education, Prof Sechaba Mahlomaholo, and the Head of the Department of English, Prof Helene Strauss.”

Now, more than 170 young men have access to a growing library that is expected to hold 1500 books by September, when Sinoxolo steps down as the Prime. According to Bongani Mtotoba, the RC: Academics and librarian, some residents have made pledges to help expand the collection. “The response has been quite positive from the guys,” he said.

Borrowers are required to submit a book review upon returning the book. This feedback will be compiled by the English Department into a book available to the public.

Khayalami’s pioneering spirit has also seen the residence run a successful writing competition in 2015. It has since been introduced to the rest of the East College, and now will take place annually.

For more information on how to donate books or enter the writing completion, contact Sinoxolo on 0783332203 or semsinoxolo@hotmail.com.
