The James Webb Space Telescope (JWST) is set to be launched soon, and it promises to provide us with unprecedented insight into the early universe. A recent study has revealed that JWST will be able to analyze the structure of massive galaxies that formed in the early universe, providing us with new information about the formation of galaxies. The results of the study suggest that JWST will be able to detect the presence of massive galaxies that formed only a billion years after the Big Bang. This is a significant finding, as it suggests that galaxies grew rapidly in the early universe, and that the process of galactic formation was more efficient than previously thought.
