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.

Double achievement for Prof. Paul Grobler

Early this year, two journal editions appearing almost simultaneously in Europe featured cover photographs based on papers by Prof. Paul Grobler of the Department of Genetics and his collaborators.

These papers stem from collaborations with Prof. Gunther Hartl at the University of Kiel (Germany) and Dr Frank Zachos from the Natural History Museum in Vienna (Austria). Both papers cover aspects of the genetics of southern African antelope species.
 
The first paper appeared in the Journal of Zoological Systematics and Evolutionary Research” (from the Wiley-Blackwell group). This was titled “Genetic structure of the common impala (Aepyceros melampus melampus) in South Africa: phylogeography and implications for conservation”.
 
In this paper, the team analysed impala from various localities in South Africa to determine the relationship between distribution and genetic structure. The results suggest a clear relationship between genetic characteristics and habitat features that regulate gene flow.
 
The second appeared in the journal Mammalian Biology (from the Elsevier group), with the title “Genetic analysis of southern African gemsbok (Oryx gazella), reveals high variability, distinct lineages and strong divergence from the East African Oryx beisa”.
 
Here, the researchers looked at various aspects of the genetics and classification of gemsbok. Among the notable findings is that gemsbok populations on the game farms studied are less inbred than previously predicted.
 
Proffs. Grobler and Hartl initiated these projects on gemsbok and impala, with sub-sections of the research later completed as M.Sc. projects by students from both South Africa and Germany.
 
Prof. Grobler has been involved with aspects of the population genetics of various mammal species since the early 1990s, and continued with this line of research after joining the UFS in 2006. Current projects in this field include work on wildebeest, vervet monkeys and white rhinoceroses.
