The James Webb Space Telescope, a flagship observatory developed by NASA, the European Space Agency, and the Canadian Space Agency, is the largest space telescope ever built, with a deployable mirror measuring 21.3 feet (6.5 meters) in diameter and four scientific instruments to observe the universe in infrared wavelengths. The mission will study the formation of galaxies, stars, and planets. JWST was launched December 25, 2021 on an Ariane 5 ECA rocket.
This is the story of the James Webb Space Telescope, told by the people who have devoted their lives to it. It is the world’s most advanced and most expensive telescope, and building it has been fraught with challenges. But it will all be worth it if the mission is successful.

A dynamic journey behind the scenes of the next step in the evolution of telescopes: NASA's James Webb Space Telescope. A new generation has been inspired to design and build this massive instrument, which is 100 times more powerful than the Hubble Space Telescope and will be a veritable time machine, capable of looking back on the origins of our universe and identifying signatures of potential life on planets far outside our solar system". With unprecedented access to the people and technologies that power its creation, including astrophysicists, engineers at Northrop Grumman, and personnel from NASA'S Goddard Space Flight Center and the Space Telescope Science Institute, the operations center for Hubble and Webb, Telescope spotlights the high-stakes mission of building this massive new scientific instrument. The film is a comprehensive look at the dynamic history of 400 years of telescopes starting with Galileo in 1609. The Webb is the next great telescope in society's ongoing mission to see farther into the universe and answer fundamental questions that have haunted mankind from the beginning of time.
