This Day in Space History: The Launch That Changed Astronomy Forever

On December 25, 2021, space history changed forever. As the Sun rose over the Guiana Space Center, an James Webb Space Telescope sat atop an Ariane 5 rocket, ready to begin a journey one million miles from Earth. Designed to see farther back in time than any telescope before it, Webb would soon open a new window on the early universe — revealing the first stars, the first galaxies, and the hidden structure of cosmic evolution. This video chronicles Webb’s historic launch, its delicate transformation in space, the deployment of its revolutionary sunshield and mirrors, and its arrival at the Sun–Earth L2 — a cold, dark, and stable orbit where science could finally begin. Decades in the making and built by thousands of scientists and engineers across the United States, Europe, and Canada, the James Webb Space Telescope represents one of humanity’s greatest scientific achievements.
