The First Sight of Black Holes using the Event Horizon Telescope

Résumé

Black holes were predicted long ago by scientists like Albert Einstein and Karl Schwarzschild. However, they had never been seen until recently: In 2009, the Event Horizon Telescope was launched. It is a telescope array that consists of a global network of 12 radio telescopes. It was built to observe two supermassive black holes which are Sagittarius A* and Messier 87 (M87). On April 10, 2019, the Event Horizon Telescope Collaboration announced taking the first direct image of a black hole. The image featured the massive black hole at the center of Messier 87 galaxy
