José Luis Gómez is a researcher at the Institute of Astrophysics of Andalusia – CSIC, but he is also one of the ten astronomers that make up the Scientific Council of the EHT, (Event Horizon Telescope), the large virtual telescope the size of the Earth that has made it possible to obtain the first image of Sagittarius A*, the black hole that resides at the center of our galaxy. In 2019, the same team already showed us what a much larger and farther black hole, the one in the galaxy M87, looks like. Two historical images that science had spent decades trying to achieve. In this interview, José Luis Gómez explains to ABC the story behind those photographs, the intense work and the many difficulties they have had to face to make this dream come true.
