Episode 5 (Special Edition): Event Horizon Telescope – First Results

with Dr Roger Deane and Dr Rhodri Evans

On 10 April 2019 six simultaneous press conferences around the world broadcast the first results from the Event Horizon Telescope – a project that was designed to take the first-ever image of a black hole.

We were fortunate to speak with two scientists involved with the project Dr Rhodri Evans a senior lecturer in physics & astrophysics at the University of Namibia, and Dr Roger Deane, Associate Professor of Physics at the University of Pretoria.

Roger spoke to us via Skype from Brussels where he was for the announcement and explained the exciting result and Africa’s involvement in the project.

Rhodri spoke with us before the announcement at the recent Astronomy in Africa conference about plans to build a telescope in Namibia to join the EHT Network.

This artist’s impression depicts a rapidly spinning supermassive black hole surrounded by an accretion disc. This thin disc of rotating material consists of the leftovers of a Sun-like star which was ripped apart by the tidal forces of the black hole. Shocks in the colliding debris as well as heat generated in accretion led to a burst of light, resembling a supernova explosion.
