Naledi Filita is an nGAP Lecturer in the Department of Languages in Education.
The University of the Free State (UFS) is celebrating Youth Month by showcasing the positive influence of the institution on career development. As part of this initiative, we are sharing the stories of UFS alumni who are now working at the university.
Naledi Filita, nGAP Lecturer in the Department of Languages in Education, shares her UFS journey:
Q: Year of graduation from the UFS:
A: 2016, 2018, and 2021.
Q: Qualification obtained from the UFS:
A: Bachelor of Education, Postgraduate Diploma in Education (Curriculum Studies), and Master of Education (Curriculum Studies).
Q: Date of joining the UFS as a staff member:
A: 2021.
Q: Initial job title and current job title:
A: Lecturer.
Q: How did the UFS prepare you for the professional world?
A: I started my career as a teacher in 2015 and was later appointed to my current job. The UFS has equipped me with the knowledge and skills that enabled me to be competent in my field in various contexts. My journey as a UFS student equipped me with crucial skills, such as critical thinking, communication, teamwork, and organisational skills.
Q: What are your thoughts on transitioning from a UFS alumnus to a staff member?
A: It has been a wonderful experience so far. I was once a student teacher at this university. Due to my experiences, being able to instil knowledge and skills in student teachers is something that I am passionate about. I am grateful for the developmental opportunities and support that I receive as a young researcher.

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.
