The James Webb Space Telescope has produced the largest-ever survey map of the universe, revealing unprecedented detail of the cosmic web and the skeleton of large-scale structure.

This map tracks how galaxies formed from the universe’s infancy, about 13 billion years ago, and how they assemble within dark matter filaments, voids, and sheets.

The cosmic web—the universe’s largest known structure—comprises gas filaments, galaxy clusters, and larger clusterings that form the scaffolding of cosmic organization.

Experts say this detailed map is crucial for understanding galaxy formation and the evolution of the universe’s architecture.

The survey positions JWST as a key tool for tracing the large-scale distribution of matter and the growth of cosmic structure over time.
