We are back with the second half of season 6!

In this episode, we are joined by Kevin Govender, Chair of the National Organising Committee and Director of the Office of Astronomy for Development (OAD). With a background in Nuclear Physics, Kevin first became involved in astronomy in 2006 when he managed the Collateral Benefits Programme at the South African Astronomical Observatory (SAAO). This work ultimately led to his appointment as the inaugural Director of the OAD in 2011.

This year we get off with a bang as our very own Jacinta has a new paper out and takes her turn in the hot seat to tell us all about it! Along with her colleagues, she has been part of the discovery of two giant radio galaxies using South Africa's powerful MeerKAT telescope. These galaxies are amongst the largest single objects in the Universe and are thought to be quite rare. The fact that MeerKAT detected two of these monsters in a relatively small patch of the sky suggests that giant radio galaxies may actually be much more common than previously thought.
