Imaging Black Holes

Imaging black holes involves capturing visual data of the region around a black hole, particularly its event horizon—the boundary beyond which nothing can escape. Since black holes emit no light themselves, scientists use powerful telescopes like the Event Horizon Telescope to detect radio waves emitted by hot, ionized gas swirling in an accretion disk near the black hole. These signals are collected by an Earth-sized network of telescopes, then combined with advanced imaging techniques to create a detailed map. The resulting images reveal the black hole’s shadow and the dynamics of surrounding matter, providing crucial insights into these extreme cosmic objects.
