摘 要：On Christmas Day 2021, NASA and the ESA launched the long-delayed James Webb Space Telescope (JWST) — a mission conceived over 30 years ago, with costs twenty times the original estimate. The U.S. government nearly canceled the project, but public support kept it alive. To some, JWST is the successor to the Hubble Space Telescope, which transformed astronomy since the 1990s. Others see it as a time machine, gazing billions of years into the past to our universe’s infancy, also a tool to answer profound questions: Are we alone? Could life exist in distant galaxies?In this talk, I’ll explore JWST’s origins, groundbreaking design, orbit, scientific missions, and the challenges it overcame before launch. Designed for a general audience, this presentation will appeal to anyone captivated by space, astronomy, and the mysteries of the cosmos.
