UFS students will be performing at the virtual ICDF on 24 September 2020.
On 24 September 2020, South Africa will be celebrating Heritage Day. For the 25th anniversary of this celebration, South Africans are encouraged to celebrate their culture and the diversity of their beliefs and traditions in the wider context of a country that belongs to all its people. Dr Chitja Twala, Vice-Dean: Faculty of the Humanities at the UFS, says: “The importance of the day is that we must celebrate who we are and learn from each other.” The University of the Free
State (UFS) has a long tradition of commemorating Heritage Day and the ideas underpinning it. One way in which the UFS celebrates and recognises the tapestry of diverse cultures represented on its campuses is through its International Cultural Diversity
Festival hosted by the Office for International Affairs. The purpose of the event is to highlight on Heritage Day that international cultural diversity is a central tenet of the UFS community.
Pursuant to the tremendous challenges caused by the COVID-19 pandemic globally, the International Cultural Diversity Festival will this year be celebrated in a virtual format. Even during this uncertain time, it is important to find time to celebrate
our uniqueness and to appreciate one another’s heritage and culture in the spirit of our humanity.
Date: 24 September 2020
Time: 10:00
No registration is required!
For the 2020 Heritage Month celebrations, let us share elements about ourselves that make us proud of who we are! The diverse contributions to the 2020 virtual International Cultural Diversity Festival activities will highlight the university’s commitment towards creating a diverse, challenging intellectual environment. As a research-led university, the UFS strives to provide an environment in which new ideas are incubated and debated, contributing to its transformation process and African unity.

H.E.S.S. (High Energy Stereoscopic System) scientists publically revealed their latest galactic discovery in the international science journal, Nature, on 16 March 2016. These scientists were able to pinpoint the most powerful source of cosmic radiation – which, up to now, remained a mystery.
Part of this team of scientists are Prof Pieter Meintjes and Dr Brian van Soelen, both in the University of the Free State (UFS) Department of Physics. Dr Van Soelen explains that they have discovered a proton PeVatron – a source that can accelerate protons up to energies of ~1 PeV (10^15 eV) – at the centre of the Milky Way. The supermassive black hole called Sagittarius A has been identified as the most plausible source of this unprecedented acceleration of protons.
The protons are accelerated to Very High Energy (VHE) gamma rays. The energy of these protons are 100 times larger than those achieved by the Large Hadron Collider at CERN (the European Organization for Nuclear Research).
According to Dr Van Soelen, the fact that this research has been published in Nature demonstrates the importance and pioneering nature of the research conducted by H.E.S.S. The H.E.S.S. observatory – operational in Namibia – is a collaboration between 42 scientific institutions in 12 countries.
In 2006, H.E.S.S. was awarded the Descartes Prize of the European Commission – the highest recognition for collaborative research – and in 2010 the prestigious Rossi Prize of the American Astronomical Society. The extent of the observatory’s significance places it among the ranks of the Hubble Space Telescope and the telescopes of the European Southern Observatory in Chile.
“The next generation VHE gamma-ray telescope,” Dr Van Soelen says, “will be the Cherenkov Telescope Array (CTA), which is currently in the design and development stage.” Both Dr Van Soelen and Prof Meintjes are part of this project as well.
H.E.S.S. has issued a complete statement about the paper published in Nature.
