James Webb Discovered The Oldest Galaxy Ever Seen!

In late 2022, the James Webb Space Telescope captured light that had been traveling through space for more than 13 billion years—revealing the oldest confirmed galaxy ever observed. This galaxy, known as JADES-GS-z14-0, existed when the universe was just 290 million years old, during the earliest moments of cosmic history. In this video, we journey back to the universe’s first chapter—before mature galaxies, before heavy elements, and before cosmic structure fully emerged. You’ll discover how astronomers measure extreme cosmic distances, why infrared light allows Webb to see further back in time than any telescope before it, and how this single discovery is forcing scientists to rethink how fast galaxies could form after the Big Bang. We explore: • How redshift reveals the age and distance of ancient galaxies • Why JADES-GS-z14-0 is far more massive and chemically evolved than expected • What its oxygen and carbon signatures tell us about the first stars • How early galaxies shaped the Epoch of Reionization • And whether these findings challenge our current cosmological models This is not just a record-breaking discovery—it’s a direct glimpse into the universe’s dark ages, when the first stars ignited and reality itself was taking shape. If you’re fascinated by astronomy, cosmology, and the origins of everything we see today, this video takes you as close as possible to the beginning of time itself.
