Assembling an Image of the Shadow of a Black Hole

In a mind-boggling excerpt from Seth Fletcher’s book Einstein’s Shadow: A Black Hole, a Band of Astronomers, and the Quest to See the Unseeable (published by Ecco), the author probes the meticulous process behind the Event Horizon Telescope (EHT). In fact, a series of collaborative data sets collected in 2017 by eight telescopes around the planet, the EHT aims to create an image of the shadow of a black hole using vast amounts of cross-referenced and corroborated information. Fletcher’s insight and prose captivates as much the scientific developments, and the excerpt—published by the New York Times Magazine—frequently stuns with unimaginable facts.
