THE PLANET IS THE CAMERA
The thing we see as an “image” was constructed from data produced not by a conventional camera, but by Event Horizon, a network of telescopes harmonized to focus on the same location at the same time. The resolution of any image depends on the aperture of the camera, and this noncontiguous perception engine linked telescopes from Greenland to Antarctica— an aperture as wide as the Earth. To make this image, our planet itself became the camera, peering out and looking back in time at ancient light that traveled to Earth—indeed, in this case looked out at time. Locally, the eight sites of the Event Horizon array were locked into synchronization by a GPS time standard and after their scans, five petabytes of data were developed into the “image” of the black hole. The mechanism is less a camera than a vast sensing surface: a different kind of difference engine. What we see in the resulting image is the orangey accretion disc of glowing gas being sucked into the void of M87*, outlined by all the non-void it is about to consume. It is 6.5 million times more massive than our sun and roughly 53 million light years away. The light that hit the Event Horizon telescopic sensing array was emitted during the early Eocene period here on Earth, a time of dramatic climate methane flux. Much closer by, there is a supermassive black hole in the center of our Milky Way. That’s right, we have always been circling an omnivorous void.
