In April of 2017, all 8 of the telescopes/telescope arrays associated with the Event Horizon Telescope pointed at Messier 87. This is what a supermassive black hole looks like, and the event horizon is clearly visible. (EVENT HORIZON TELESCOPE COLLABORATION ET AL.)The first image of an Event Horizon is here. Here’s what it means.Variety isn’t just the spice of life, but a natural consequence of living in our Universe. Gravitation, obeying the same universal laws on all scales, creates clumps and clusters of matter in an enormous suite of combinations, from tenuous clouds of gas to massive stars, all assembled into galaxies, clusters, and a great cosmic web.From our perspective on Earth, there’s an enormous amount to observe. However, we can’t see it all. When the most massive of stars die, their corpses become black holes. With so much mass in such a small volume of space, nothing — no signals of any type — can get out. We can detect the matter and light emitted around these black holes, but within the event horizon, nothing escapes. In an incredible success story for science, we’ve just successfully imaged an event horizon for the first time. Here’s what we saw, how ...
