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.

UFS receives record number of applications

2011-12-31

The University of the Free State (UFS) is looking forward to the start of the new academic year in January 2012, when thousands of new students will be joining the Kovsie family.

The UFS received almost 13 000 applications for studies in 2012. This is an increase of about 80% compared to the total number of applications received in 2010 for studies in 2011.

This increase is partly attributed to the university’s new method in approaching prospective students and the marketing initiatives followed during 2011. These included visits to various schools in the country by the Vice-Chancellor and Rector, Prof. Jonathan Jansen.

“This shows that the UFS is becoming a preferred place of study. Unfortunately, we can only take in about 4 000 first-years from these applications. We will, of course, choose the best and most diverse class of students,” says Prof. Jansen.

The university’s marketing initiatives will be intensified next year where students will take part as ambassadors in the university’s student recruitment campaigns for 2013.

Mr.Rudi Buys, The Dean of Student Affairs at the UFS, says Prof. Jansen’s visit to various schools in the country was very successful. This will be continued in 2012 and student leaders from residences, associations as well as the Student Representative Council will accompany him on these visits during the course of the year.

“These learners, just like our students, are part of a new generation of new democratic South Africans. Our students are excellent examples of youth leadership in the country and we are very excited about all our initiatives,” Mr Buys said.

The UFS is aware of the fact that learners will only receive their final Grade 12 results in January 2012. Final admission will therefore only be granted upon the submission of a certified copy of the matriculation results. Fax these results to 086 586 8947 or e-mail to applications@ufs.ac.za as soon as it is available.
