James Webb Telescope Maps the Cosmic Web in Unprecedented Detail
JWST's largest-ever survey reveals how galaxies have evolved over 13 billion years within the vast structure known as the cosmic web.
Astronomers have reconstructed the “skeleton” of the cosmos in unprecedented detail, thanks to the largest-ever survey conducted by the James Webb Space Telescope (JWST). The resulting map reveals how galaxies have evolved since the universe’s infancy around 13 billion years ago and how they fall together in a vast structure called the cosmic web.
The cosmic web is the largest known structure in existence, home to countless galaxy clusters and clusters of clusters. It is the framework of the universe — a scaffolding of gas filaments, stars, voids, and sheets of dark matter that trace the entire large-scale organization of the cosmos.
