Naval Hill Planetarium celebrates its first decade

09 November 2023 | Story Prof Matie Hoffman

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).

Researcher uses NRF funding for studies to conserve plant and animal life

2017-04-18

It is difficult to survey all different types of
plants and animals and is therefore necessary to
choose one representative group. Butterflies are
relatively cheap and easy to sample. They are
known to be linked to specific habitats and to
respond to human pressures, such as farming.

Earth is the only planet we know of that contains life. The variety of different plants and animals is remarkable: from the giant whales that swim our oceans, to the tiny mosses that grow on the shaded sides of rocks. Many of these plants and animals are important to humans. For example, trees provide us with oxygen to breathe, bees pollinate our crops and owls control pests. More importantly though, we can tell a lot about society from the way it cares for nature. Humans are the custodians of the planet and the way we care for nature reflects the way we value life.

Dr Falko Buschke, Lecturer at the Centre for Environmental Management at the University of the Free State, is interested in understanding how the distribution of biodiversity [the variety of living things in nature] in time and space influences the way we should conserve and manage nature.

Earth is losing biodiversity faster than at any time in human history
The planet is losing biodiversity faster than at any time in human history. “There is an urgency to conserve plants and animals before they are lost forever. Nature is complex, so the way we study it should embrace this complexity. We should not rely on limited data on one type of species from one place and assume that it will also apply elsewhere. Instead, it is important that biodiversity research is comprehensive in the types of plants and animals while also considering that ecological and evolutionary processes vary through time and across geographic space,” he said.

To conduct his research, Dr Buschke uses a variety of research tools, including biological data surveyed directly from nature, spatial data from satellite remote sensing and geographic information systems databases, and data generated though custom-built computer simulations.

plants and animals before they
are lost forever."

Field work in the eastern Free State
Although parts of the eastern Free State are considered a global priority for biodiversity conservation, it is mainly privately owned commercial farmland. This means that it is important that plants and animals can survive despite living side by side with agricultural production.

“My project investigates whether the sandstone outcrops, known as inselbergs (island-mountains), are safe havens for plants and animals. Because it is difficult to survey all the different types of plants and animals, it is necessary to choose one representative group. That is where butterflies come in. Butterflies are relatively cheap and easy to sample. They are known to be linked to specific habitats and to respond to human pressures, such as farming,” he said. “Once this butterfly data is collected, it can be linked to satellite information on plant growth patterns. This will provide a clearer picture of whether plants and animals can persist side-by-side with commercial agriculture”.

Dr Buschke has just begun surveys that will carry on until the end of this year. “This 12-month project is funded under the Foundational Biodiversity Information Programme through the South African National Biodiversity Institute (SANBI) and the National Research Foundation (NRF).
