James Webb Telescope Maps Universe's Most Detailed Cosmic Web

Across 13.7 billion years of cosmic time, humanity has finally traced the skeleton of the universe itself. NASA's James Webb Space Telescope has produced the most detailed map ever made of the cosmic web — the vast filamentary structure along which galaxies cluster and dark matter flows. Where earlier instruments offered only shadows and suggestions, Webb offers definition, transforming a theoretical architecture into a visible, mappable reality. In doing so, it opens a new chapter in our oldest inquiry: how did the universe build itself, and why does it look the way it does?
