A decade ago, the former Lamont-Hussey Observatory in Bloemfontein became Southern Africa’s first digital planetarium. Thanks to a collaboration between the University of the Free State (UFS), the Mangaung Metropolitan Municipality, the Department of Science and Innovation, and the Free State Province – as well as donations from trusts, foundations, and businesses – the project has grown and thrived.

Many different shapes, one place

The Naval Hill Planetarium was established in the old Lamont-Hussey Observatory. After the closure of the astronomical observatory, the buildings were refurbished and used by PACOFS as the Observatory Theatre. When the site became available again, it was envisioned to turn it into a planetarium. After many years of hard work, the newly refurbished buildings were opened in 2013 as the Naval Hill Planetarium – the first digital planetarium in Africa south of the Sahara. 

The decade has seen many changes on the site of the former Lamont-Hussey Observatory, founded by the University of Michigan in 1927 to study double stars through the largest refracting telescope in the Southern Hemisphere. Improvements include the conversion of the old telescope building into a modern digital planetarium, the refurbishment of the structure of the old Lamont telescope and its installation as a display outside the old telescope dome, an observing platform, and a new hall for environmental education. The planetarium and the hall are now known as the Centre for Earth and Space, and developments are continuing.

Partners who have supported the project include the American Museum of Natural History (AMNH), the University of Michigan, Old Mutual, Sun International, the Hermann Ohlthaver Trust, ArcelorMittal, the Joan St Leger Lindbergh Charitable Trust, and the CB van Wyk Gesinstrust. In 2022, the Raubex Group and First Technology supported the University of the Free State to upgrade the planetarium’s projection system. Volunteers, including the Friends of the Boyden Observatory and the Naval Hill Planetarium, as well as the Friends of Franklin, have played an invaluable role in supporting and developing this community asset. The planetarium is managed by the Department of Physics at the University of the Free State.

A time to celebrate

During November and December 2023, the planetarium’s first decade will be celebrated with events and special shows, including the South African premier of the AMNH full-dome film, Worlds Beyond Earth. The board of the Southern African Large Telescope (SALT) – the largest single optical telescope in the Southern Hemisphere – will attend the premiere. Many international partners are involved in SALT, and AMNH is one of the shareholders in the SALT Foundation. As part of the partnership between the AMNH and SALT, AMNH provides sponsorship for education and outreach efforts in South Africa. The Naval Hill Planetarium benefits from this initiative and receives content for the planetarium in the form of AMNH full-dome films.

In addition to regular school shows, there will be two public shows every Saturday in November and December – one show in English and one in Afrikaans. In December, there will be additional shows for children. Bookings for shows should be done through Computicket, click here to book. The planetarium can accommodate group bookings and functions (enquiries at +2 51 401 9751 or ficky@ufs.ac.za).

Emma Sadleir talks about social media etiquette

“We have all become celebrities, we have become social figures because of our power to publish information. We have all become brands, and we need to protect our brand. Digital content is sometimes dangerous content,” said Sadleir.

On 11 May 2016, the University of the Free State, in collaboration with the Postgraduate School, hosted, Emma Sadleir, a leading social media expert, in the Equitas Auditorium on the Bloemfontein Campus. She is an admitted advocate, specialising in social media law.  Dr Henriette van den Berg, Director of the Postgraduate School, described Sadleir’s presentation as a privilege for all the staff and students who attended.

Sadleir said that there are two important rules that staff and students of an institution should try to follow. The first is not to bring the name of the institution into disrepute; and the second is not to breach the goodwill of the institution or, in other words, not to bite the hand that feeds you.

“The common law, even if there is no policy, is that anything that brings the company into disrepute can lead to disciplinary consequences up to termination,” said Sadleir.

Sadleir focused on hate speech and free speech, stating that free speech is a right that is entrenched in the constitution, but, like every other right, it has limitations. She mentioned Penny Sparrow, Matt Theunissen, Velaphi Khumalo, and Judge Mabel Jansen, all of whom have been lambasted by the public over their racist posts on social media. Sadleir stressed that, even on social media, content has to be within the confines of the law, and people must remember our rights are not absolute. We have a lot of freedoms, but no one cannot disseminate hate speech.

“Would you publish whatever you thinking on a billboard, close to a busy highway with your name, picture and employers details or the institution you studying at? If you have no grounds to justify the comment, do not post it,” warned Sadlier.  

According to the South African Bill of Rights, everyone has the right to privacy, but an expectation of privacy has to be enforced. She said people over-document their lives on social media, decreasing your right to privacy drastically. “It is like CCTV footage of your life. It is simple, the more you take care of your privacy, the more you have,” said Sadleir.

Sadleir said it was important for Facebook users to have privacy settings where they can review posts where they are tagged. According to Sadleir, managing your reputation is not only limited to what you post about yourself but also managing what others post about you.

She cited a 2013 case in the Pretoria High Court in which a new wife wrote a scandalous Facebook post about her husband’s ex-wife, tagging the husband in the post. The courts found both the new wife and the husband guilty of defamation.

“If you have been tagged in something but have not been online and seen the content, you are then an innocent disseminator. The moment you are aware of the post you are liable for the content,” said Sadleir.

“It takes 20 years to build a reputation and five minutes to ruin it. If you think about that, you'll do things differently,” Sadleir said, concluding her presentation with the quotation from Warren Buffet.
