The Event Horizon Telescope (EHT) is a global array of radio telescopes working together to capture images of supermassive black holes’ immediate environments. By synchronizing these telescopes, scientists create a virtual telescope the size of Earth, capable of producing unprecedentedly detailed images. The EHT made history in 2019 by capturing the first-ever direct image of a black hole’s event horizon in the galaxy M87. This remarkable achievement provided visual evidence supporting Einstein’s theory of general relativity and offered insights into the extreme environments surrounding these cosmic phenomena. The EHT continues to push the boundaries of astrophysical research, aiming to image more black holes and further our understanding of these enigmatic celestial objects.
