The James Webb Space Telescope is the largest and most powerful telescope in space, designed to uncover the secrets of how galaxies were formed and how the universe was created. It is an engineering marvel that required thousands of people and many years to design and develop. The telescope is an infrared observatory, which means it gathers light from heat, and it is located about a million miles from Earth to avoid the heat of the planet. The telescope is high-stakes, as it cannot be repaired in orbit, so extensive testing was conducted before it was launched in 2021.
