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.

Study shows that even cheating monkeys alter their behaviour to avoid detection and punishment

A recent article headed by Dr Aliza le Roux from the University of the Free State Qwaqwa Campus’ Department of Zoology and Entomology, asserts that cheating and deception is not only a human phenomenon - it is also found in non-human animals.

“Our specific study investigated cheating and punishment in geladas. While human beings are known to deceive one another, and punish cheaters that get caught, it is actually very rare to find proof of this kind of behaviour in non-human animals,” said Dr Le Roux.

“We don't know if this is because humans are uniquely deceitful, or if it is just that animals deal with cheating differently. Our study was therefore the first to demonstrate that gelada males and females try to deceive their partners when they are cheating on them. This means they try to hide their unfaithful behaviour.” This is therefore the first investigation to document tactical deception in primates living in a natural environment.

“We also showed that the cuckolded males then punish the cheaters, but could not determine if the punishment actually caused cheaters to stop cheating,” said Dr Le Roux.

This on-going and long-term study continues to observe the population of wild geladas in the Simien Mountains National Park in Ethiopia. The study investigates primate hormones, cognition, genetics, social behaviour and conservation, and is done in collaboration with the Universities of Michigan and Pennsylvania.
