This historic image is the first direct visual evidence of a black hole’s shadow, captured by the Event Horizon Telescope (EHT) — a global network of synchronized radio telescopes acting like a planet‑sized observatory. It reveals the supermassive black hole at the center of the Messier 87 galaxy in the Virgo cluster, surrounded by a glowing ring of hot gas shaped by intense gravity. While the dark center is the black hole’s shadow, the bright ring marks light bent by the extreme gravitational field, providing unprecedented insight into black hole physics and confirming key predictions of Einstein’s general relativity.
