The James Webb Space Telescope, the largest and most powerful telescope ever built, finally launched into space on December 25, 2021, after a series of delays and technical challenges. The James Webb is an international collaboration between NASA, the European Space Agency (ESA) and the Canadian Space Agency (CSA), and its goal is to explore the early universe and search for signs of life on other planets.
With a 6.5-meter-wide lens and a suite of advanced instruments, the telescope is expected to be able to observe some of the most distant and oldest objects in the universe, offering new opportunities for research and discovery in astronomy and science in general.
It also has a mirror system, called the Optical Telescope Element, which has the valuable mission of capturing light from space to direct it to the scientific instruments in charge of its analysis. It consists of 18 hexagonal segments made of beryllium and coated with a gold film, designed to function as a single piece, but folded in such a way that they can fit inside a rocket
