James Webb Space Telescope reveals ancient galaxies in unprecedented detail.

The James Webb Space Telescope has captured an image of 45,000 galaxies, including 700 new discoveries, some of which are the youngest ever observed. The telescope's unprecedented detail is helping scientists understand the secrets of our early universe, including the Epoch of Reionization. The discovery of strong emission lines in the young galaxies suggests that hot, massive star formation could have been a key driver of the epoch. Webb's observation of the Great Observatories Origins Deep Survey is part of its JWST Advanced Deep Extragalactic Survey program.
