The Event Horizon Telescope (EHT) is like a huge telescope that is made out of many small telescopes around the world. It works by connecting these all smaller telescopes together to act like one big telescope that is the same size as the Earth. With this new super-telescope, scientists can take pictures really far away in space! They can use it to study some of the biggest and most mysterious objects in the universe like black holes. They can use the pictures to learn more about how black holes work and what they can tell us about the universe.
