The astronomers can be delighted: telescopes are multiplying around the world. And alongside the giants that emerged from the ground between the 1980s and 2000s, the titans are coming! In 1977, the mirror principal of the biggest telescope of the world was 5 meters in diameter. In 2024, theELT will open a eye huge 39 meters in diameter! It is mainly in Hawaii, at an altitude of 4,200 meters in the center of the Pacific Ocean, and in the Chilean Andes that telescopes continue to flourish. We invite you to discover them in a world tour in 20 photos of the largest modern telescopes.
