The James Webb Telescope (JWST, or Webb) has revealed hundreds of ancient galaxies that could have been among the universe’s first members — a jump from only a handful previously known to exist at the time.

As early as 600 million years after the great explosionThese very young galaxies boast complex structures and clusters of star formation, a new study reports. The study is part of an international collaboration called the JWST Advanced Deep Extragalactic Survey (JADES), which collected a month’s worth of observations from two small spots in the sky: one in the constellation Ursa Minor and the other in the direction of the Fornax cluster. Within this region were more than 700 newly discovered young galaxies that seemed to reveal the universe as soon as possible.
