Event Horizon Telescope (EHT)

The Event Horizon Telescope (EHT) is a network of synchronized radio observatories around the world that work together to form a virtual Earth-sized telescope. This powerful setup captures images of black holes' immediate surroundings, specifically their event horizons—the points beyond which nothing can escape. In 2019, the EHT produced the first-ever image of a black hole's shadow in galaxy M87, providing direct visual evidence of these mysterious objects. By combining data from multiple sites, the EHT achieves the resolution needed to observe phenomena previously beyond reach, advancing our understanding of extreme gravity and spacetime.
