Astronomers have made significant strides in mapping the cosmic web, a vast structure composed of dark matter and gas that links galaxies. Using the James Webb Space Telescope (JWST), researchers from the University of California, Riverside have produced the most detailed map of this structure to date. Bahram Mobasher, a professor at UCR, noted that the new data reveals the cosmic web as it appeared just a few hundred million years after the Big Bang, a period previously difficult to study. The enhanced resolution allows astronomers to observe the evolution of galaxies within these filaments and clusters, providing insights from a time when the universe was a billion years old to the present. Lead author Hossein Hatamnia emphasized the importance of this research in understanding cosmic structures. The findings were documented in a paper published in The Astrophysical Journal.
