The James Webb Telescope (JWST or Webb) has discovered hundreds of ancient galaxies that could be among the first members of the universe – just a few hops from what was known to exist at the time.

600 million years later Big bang, these very young galaxies showed 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 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. There were more than 700 newly discovered young galaxies in the region, which together with the cosmos appeared to be the earliest.
