A few months ago, a collaboration called the Event Horizon Telescope presented the first direct image of a black hole; or more specifically, of the radiation created by accelerated particles at its event horizon. The EHT is a Very Large Baseline Interferometer, in which radio telescopes all over the world are computationally connected to obtain resolutions that are not possible with one telescope. In the episode I chat with Heino Falcke, the chair of the EHT science committee, about the science, the telescope, what it took to get it going, and image reconstruction.

I really enjoy these detailed podcasts.
A minor comment: In the introduction on the Event Horizon telescope, at 00 minutes 50-55 seconds, M87 is described as a star. It is actually a galaxy.
