The story behind the first ever black hole image EHT Collaboration

In the May edition of the Physics World Stories podcast, Andrew Glester reflects on the biggest astronomy story of the year – the first ever image of a black hole and its “shadow.” Unless you’ve been living in a black hole yourself, you will have seen the glowing donut/eye of Sauron/smiley face, which is actually the supermassive black hole at the centre of the M87 elliptical galaxy, some 55 million light-years from Earth. The image represents an incredible feat of science and engineering, produced from petabytes of data captured by the Event Horizon Telescope (EHT), a network of individual radio telescopes and telescopic arrays scattered across the globe.
