The James Webb Space Telescope has changed how astronomers observe the universe, allowing them to detect light from galaxies that formed shortly after the Big Bang. The James Webb Space Telescope has changed how astronomers observe the universe, allowing them to detect light from galaxies that formed shortly after the Big Bang. This book explains how the telescope works, why infrared observation matters for studying distant cosmic objects, and what its early findings suggest about the formation of galaxies, stars, and planetary systems. Generated with the help of artificial intelligence, the text draws on published scientific research to give you a clear, structured introduction to the mission's goals and methods. You will learn about the telescope's design and instruments, the challenges of its deployment, and how its data is reshaping models of cosmic history. Written for readers with no specialized background, this book offers a factual starting point for understanding one of contemporary astronomy's most significant instruments and its ongoing contribution to our knowledge of the early universe.
