Music: Niklas Falcke Animation zooming into M87 to show its accretion disk, ray-traced images and blurring due to instrument noise, demonstrating how the image obtained with the Event Horizon Telescope fit into a bigger picture.

With a technique called Very Long Baseline Interferometry they were combined into a large "virtual" telescope as large as the Earth. Credit: C. Fromm & L.
