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.

A call for next generation of professors: Apply for the Vice-Chancellor’s Prestige Scholars’ Programme

2014-12-19

Examples of the rector's prestige scholars' international footprint: Dr Olihile Sebolai, Fulbright scholar (left) returned to the UFS after six months at the University of Birmingham and three at the University of Missouri. Dr Cilliers van den Berg (right) visited Cornell University on a ten-month sabbatical.

The Vice-Chancellor’s Prestige Scholars’ Programme (PSP) seeks to identify, develop and promote the next cohort of the most promising and talented UFS academic members of staff who obtained a doctoral degree within the last five years or will graduate by June 2015.

Scholars identified benefit from an intensive programme of academic and professional support that includes an advanced residential programme, exposure to leading scholars, concentrated reading and writing programmes, high-level seminar participation and presentation, nuanced publication schedules and personal mentoring and advice, including participation in the annual PSP mock NRF rating and the development of a postdoctoral intellectual project for funding submission (Thuthuka, and similar).

Past prestige scholars have become Fulbright scholars, received funding from among others the Association of Commonwealth Universities, the Japan Society for the Promotion of Science, Erasmus Mundus, NRF Blue Skies, Thuthuka, etc. They have spent time at universities in Canada, the USA, United Kingdom, Europe and Japan.

This year the selection process will be anticipated by pre-selection. Final selection to the programme will take place in September 2015. The selection is highly competitive, and aimed at those young scholars with the potential to obtain upper-level NRF ratings (Y1 and P).

Criteria for selection:

Recently obtained a PhD degree.
Evidence of an active publication record.
Early recognition of scholarly work, e.g. successful funding/grant applications and academic awards.
The early development of a post-doctoral intellectual project that shows evidence of scholarly “potential” (defined by the NRF Y-category).
Indication of the young scholar’s understanding of what their envisaged postdoctoral endeavours will contribute to the body of disciplinary knowledge.
Full participation in the pre-selection residential programme and activities is a requirement for selection.

Call for interest: 2015 (PDF)

Requests for further information can be directed to Prof Jackie du Toit at dutoitjs@ufs.ac.za.

Applications close on 16 February 2015.
