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.

Student gives hope to childhood cancer patients

2015-10-16

Siphokuhle Jama believes that the underprivileged are also destined to reign.

The inaugural ‘Dance and Musical Childhood Cancer Fundraising Day’, held on Saturday 26 September 2015 at the Free State Childhood Cancer (CHOC) Foundation, was “a huge success,” according to Siphokuhle Jama, the organiser.

Siphokuhle is a second-year BSc Agricultural Economics student at the University of the Free State (UFS), who has devoted his life to bettering the lives of the less fortunate. The 21-year-old self-proclaimed motivational speaker, entrepreneur, and budding author was inspired by his humble beginnings to found the Destined to Reign Foundation, which champions various community initiatives in both his home town of Mtata and Bloemfontein.

To support the fight against childhood cancer, the young philanthropist took it upon himself to invite music and dance fanatics either to perform or to enjoy spectatorship for a good cause. The impressive support received from the UFS, Universitas Academic Hospital, and Central University of Technology (CUT), various artists, and the community has contributed towards ensuring that the inaugural fundraiser was a prelude to annual events to come.

Singers, dancers, and poets entertained the audience with vigour, making the day one of the most special for the young children, who spend their days and nights at the CHOC House, with little to do but undergo radiation and chemotherapy and await a discharge date. .

All proceeds went towards basic needs, such as food, toiletries, and clothing for the children residing at the House, which is located in the same suburb as our university. In addition to accommodating dozens of cancer patients and their mothers, the House also assists with the treatment and rehabilitation of children suffering from life-threatening blood disorders. Thus, the fundraiser served to promote awareness of these health conditions.

Siphokuhle’s passion for giving hope to the underprivileged was unveiled by a school community engagement project 14 years ago. He has never looked back.“It has always been in my heart to serve my community,” he said.
