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.

Medical student stars in local movie
2015-10-15


Sung-Hoon as the on-screen character Operator 2

Sung-Hoon Kim’s dream of starring in a movie became a reality with the release of Reconnect on 16 October 2015 in Nu Metro cinemas across the country.

The second-year medical student at the University of the Free State transitioned into a professional actor in December 2013, when he made the leap from his high school drama stage to shooting for the big screen.

“I did plays in high school where I had roles like Simba in The Lion King,” said the first-time movie star. 

The film is a purely South African creation. It is set in Potchefstroom and Klerksdorp, Sung-Hoon’s former and current hometowns. Sung-Hoon plays two major roles: XJ-1- a robot, and the on-screen role of artificial intelligence Operator 2 at SKY CORP - an international intelligence company that protects top secret information from around the world.

Reconnect was directed by the late Marius Swanepoel, who Sung-Hoon described as “a great blessing to all those privileged enough to have known him.” The movie explores the relationship between human beings and artificial intelligence.

Eric Scott discovers XJ-1 at an abandoned warehouse, and transfers him to SKY CORP where he becomes destructive. Eric and his friend, Jason, are then faced with the challenge of containing the situation, and saving the company which XJ-1 has infected with a dangerous virus. As the science-fiction action unfolds, viewers catch a glimpse into the life of XJ-1.

Shooting the movie was an exciting experience for Sung-Hoon. “It was quite fun because I like imitating voices,” he said.
