About this podcast

Join us for a safari through the skies!

Season 6 coming June 5th!!!

The Cosmic Savannah podcast showcases world-class, afro-centric astronomy and astrophysics. It is for a general audience and anyone can listen. No astronomy knowledge needed!

Africa’s beautiful dark skies and vast plains make it an ideal place for cutting-edge astronomy research. Hear about the fascinating people and discoveries coming out of Africa and how they are relevant on the world stage.

Each episode, we chat to guests involved in the world of astronomy across the African continent. New episodes are released on a fortnightly basis during a season.

The podcast is produced and hosted by Dr Jacinta Delhaize from the University of Cape Town, Dr Daniel Cunnama from the South African Astronomical Observatory and Dr Tshiamiso Makwela from the University of Cape Town and MPIA.
