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.

With water being considered as a threatened resource in the world, the Health and Wellness Centre and the Faculty of Natural and Agricultural Sciences at the University of the Free State (UFS), in collaboration with Provincial Government and private stakeholders, hosted a Water Extravaganza at the Bloemfontein Campus.

The UFS has a Strategic Academic Cluster: Water management in water-scarce areas, which has a number of participating academics and postgraduate students who are all looking to combat the problems associated with water, the threatened resource, in South Africa.

Prof Maitland Seaman, Director of the cluster for Water management in water-scarce areas, says South Africans should remember that, when and where there is water, you only have temporary use of it.

He also warns that water needs to work, otherwise it will become useless.

“If water is to work, we must conserve the natural ecosystems that purify it and make it available for further use; we must use it judiciously and optimally (for agriculture, industry and domestic use); and we should not pollute our water sources.”

Prof Seaman will deliver a presentation on the Modder River as the life blood of Bloemfontein at the Water Extravaganza. Other presentations will be on fracking, water-related disasters and the water situation in Mangaung.
