This is an interesting and informative article about the use of interferometry in astronomy, especially for the layperson, and ends with the decade long work needed to create the Event Horizon Telescope (EHT). This was the "telescope" that gave us our very first view of a black hole, Powehi, and the JCMT and SMA on Mauna Kea were the most important link in the chain of telescopes used. Without them the image would have been impossible.

"In 2009, radio observatories across the world agreed to work together on an ambitious project. They used interferometry to combine their telescopes to create a virtual telescope as large as a planet. It is known as the Event Horizon Telescope, and in 2019, it gave us our first image of a black hole."
