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.

Food insecurity at university campuses under the spotlight

2015-08-20

"Food insecurity is becoming an increasing problem at South African universities, much to the surprise of university managers." - Dr Louise van den Bergh, senior lecturer and researcher at our department of Nutrition and Dietetics

More than 70% of early university dropouts in the country were forced to abandon their tertiary studies because of food insecurity and financial need.

This was one of the conclusions drawn during the first higher education colloquium on food insecurity. The colloquium was hosted on by the University of the Free State (UFS) on the Bloemfontein Campus on 14 August 2015, where researchers from universities across the country shared their research about food insecurity on university campuses.

In South Africa, university campuses are not usually associated with food insecurity but, over the last few years, tertiary education has become more accessible to an increasing number of first-generation students and students from low-income households.

Some of the research indicated that students from lower-income households are often lacking financially, even with bursaries. The research has also shown that students frequently have to use part of their bursary money to support their families. This results in students not having enough money to buy food, which means they will do almost anything to get food.

A study by the UFS Department of Nutrition and Dietetics found that as many as 60% of our students are food insecure, and experience hunger frequently. This study was the first of its kind in South Africa. In 2011, the UFS launched the No Student Hungry Bursary Programme to provide food bursaries to food-insecure students.

At the opening of the colloquium, Prof Jonathan Jansen, Vice-Chancellor and Rector of the UFS, said by helping students with a basic commodity like food, you give them much more than food; you give them humanity and dignity.

Dr Louise van den Bergh, senior lecturer and researcher in the UFS Department of Nutrition and Dietetics, explains that the problem is considerably more complex than just providing for students financially.

Dr Van den Bergh says that funders need to reassess bursaries, keeping issues such as food insecurity in mind, and not focusing just on tuition.
