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.

"Learning more about ourselves, our group and the world at large..."
2011-09-28

 

For the latest news from our students abroad, you can follow us on twitter and join us on facebook.

A group of 98 first-year students from our university departed from the Bloemfontein Campus’s International Offices to the OR Tambo International Airport on Thursday 22 September 2011. From there, they will be flying to New York, USA, via Dubai. Shortly after their arrival in New York, they will be welcomed by Dr Anthony Marx, the president of the NYPL.

The programme, a first in South Africa, kicked off in 2010 with 71 students visiting the USA.

The programme gives students intense exposure to the academic, social, cultural and residential lives of students abroad. A total of 150 UFS students are now part of the programme. The rest of the group of 2011 will leave for universities in Europe and Asia in January 2012.

"The group travelling to Minnesota University... We are having a great time, learning more about ourselves, our group and the world at large. Thank you for the grate opportunity!"

"by Sherilyn Roelofse - Apart from the amazing beauty of the JMU campus (Harrisonburg, Virginia), I am taking in so much! It is amazing to see how everything functions here. I am astounded by the way the food system of the university works - it's so organised! I also love how there is always something happening on campus. For example, tonight we attended a session hosted by the Harrisonburg Fire Department and we had to move through a smoke filled room. drag a deadweight-dummy, and put out a fire. And yes, we have discovered that the American campus life is pretty much exactly what it looks like on movies! ;)"
