A mosaic of 690 frames obtained with Webb's Near Infrared Camera (NIRCam) instrument which constitutes one of the first images of the CEERS survey and shows in the insets some examples of primordial galaxies

An article accepted for publication in “The Astrophysical Journal” reports the results of a study of the structure and morphology of galaxies that existed in the first three billion years of life of the universe. A team of researchers used observations conducted with the James Webb Space Telescope as part of the CEERS survey to obtain enough detail to understand what primordial galaxies were like. The conclusion is a confirmation of previous research regarding the remarkable variety of shapes and structures and turned out even superior thanks to Webb. In many of them, the structures are already quite evolved, as in closer and younger galaxies.
