During the installation of the new computer and projector equipment at the Naval Hill Planetarium, were from the left: Dieter Schwab and Alex Reither from Sky-Skan, and Prof Matie Hoffman, Barry Crous (Instrumentation), and Pat van Heerden (Department of Physics) from the UFS.

The Naval Hill Planetarium at the Centre for Earth and Space on Naval Hill was inaugurated on 1 November 2013. It was the first digital planetarium in Africa south of the Sahara. 

The Department of Physics at the University of the Free State (UFS) is responsible for the Naval Hill Planetarium (formerly the Lamont-Hussey Observatory). The department uses the planetarium to educate and inform citizens about the natural sciences. The planetarium, together with the Boyden Observatory, is also important for the display and communication of South Africa’s astronomical heritage.

The planetarium system was recently upgraded in a project that cost R6 million. According to Prof Matie Hoffman from the Department of Physics, it was time to upgrade the computers and graphic cards, and to replace the lamp projectors with laser projectors.

Funding for the state-of-the-art equipment came from the Faculty of Natural and Agricultural Sciences and the Information and Communication Technology Services (ICT Services) at the university. Businesses in Bloemfontein – First Technology and Raubex Construction – also contributed to the project. 

Presenting programmes more often

Planetarium specialists Dieter Schwab and Alex Reither from Sky-Skan Europe, based in Germany, installed the new equipment over a period of two weeks.

Prof Hoffman says the new equipment will enhance the experience of people visiting the planetarium for a close encounter with the wonders of the universe to deepen their appreciation of science and astronomy.

“Besides a clearer image with better colour, the new projectors will also be more economical to operate. This means we will be able to offer programmes at the planetarium more often,” he says. 

The upgrades also include new software. Prof Hoffman explains that the software will enable more sophisticated presentations and open the door to the use of the planetarium for higher level visualisation of scientific data where any large data sets with many variables are involved, such as climate science, astrophysics, and cosmology. 

Offering an incredible experience

After completion of the installation, a period of two weeks will be spent on training to master the use of the new equipment and the software. The public can expect the first show with the new equipment at the end of June. 

“I am most looking forward to the planetarium creating an incredible experience – better than in the past – for the public and increasing everyone's admiration and understanding of the universe. I also believe the planetarium is an excellent facility to improve students' skills in science communication, and it provides these students the opportunity to share their knowledge with the public,” concludes Prof Hoffman.

Out of the ordinary lunch with Prof Jansen
2015-08-17

Prof Jansen and the twins pose for pictures after enjoying a laugh and chat at the lunch event.

Numerous sets of twins and a set of triplets were entertained by, and enjoyed lunch with, the Vice-Chancellor and Rector of the university, Prof Jonathan Jansen.  Wednesday 12 August 2015 marked an extraordinary day in the Kovsie history book.

The Reitz Hall in the Centenary complex was filled with echoes of laughter as Prof Jansen told “twin jokes” he had Googled earlier for the occasion. Save for the humour, he said that twins and triplets represent a unique bond.  “After all, we should be striving for a way of being together,” he said, speaking about the quest for national solidarity.

Sitting in groups of six, and after the introductions, the duos and trio were soon engaged in conversation.

Anita and Mikita Miza, who were sharing a table with Marike and Ilna Marais, told stories from their childhood.

“We did not realise that we were twins until we were in grade one,” said Anita, who is studying the same course as her sister. Mikita is in the second year of her BSoc Science degree, while her twin is a year ahead. She had to remain in Mtata, their hometown, for a year while Anita began her first year. “It was the longest year of my life,” said Mikita.

Marike and Ilna are first years in Physiotherapy and Optometry, respectively. When asked by Prof Jansen what they never share, the non-identical twins were quick to reply: “clothes,” although they still share a room. When they were in high school, fellow learners struggled to believe that Marike and Ilna are twins, because of their distinctly different looks.

The lunch united strangers, who have a unique common bond, and acted as a platform to tell interesting stories that are seldom heard.
