![]() Today, in coordinated press conferences across the globe, EHT researchers reveal that they have succeeded, unveiling the first direct visual evidence of a supermassive black hole and its shadow. The Event Horizon Telescope (EHT) - a planet-scale array of eight ground-based radio telescopes forged through international collaboration - was designed to capture images of a black hole. It was the first direct visual evidence that black holes exist, the researchers said. The Event Horizon Telescope collaboration used a global network of telescopes in April 2017 to capture the first-ever picture of a black hole, which the team shared in 2019. The scientists also discovered that a significant amount of light around the black hole is polarized. In this case, analyzing how the light around this black hole at the center of the M87 galaxy is polarized allowed astronomers a sharper view and the ability to map magnetic field lines near its inner edge. Light can also be polarized when it’s emitted in hot regions of space near magnetic fields. Think about your polarized sunglasses, which help reduce glare and reflections of brightness. While the first image of this black hole and its shadow was released in 2019, the new image released Wednesday shows the cosmic body in polarized light. ![]() ![]() Astronomers have a new, more complete picture of the supermassive black hole at the center of a galaxy 55 million light-years from Earth – the first black hole ever to be imaged. ![]()
