20192019: A black hole’s shadow
A telescope network imaged a previously inaccessible object.
The first image of the black hole’s shadow in M87 was released on 10 April 2019. The Event Horizon Telescope combined observations from eight telescopes.
Joint processing created a planet-scale virtual instrument. Synchronisation, large data archives and image-reconstruction methods made the result possible.
