While the images may not seem very impressive at first glance, these hazy patches of light represent important cosmic artifacts. In the early stages of the Universe, it was covered in dark hydrogen, and only with the appearance of the first stars did light begin to penetrate this darkness, ionizing and accelerating the hydrogen.

Over time, young stars began to assemble into the first galaxies, occurring approximately 120-220 million years after these early stages. This is exactly what the new observations reflect. Analysis of infrared data taken by the James Webb Telescope allowed scientists to measure the effect of hydrogen gas on the light from galaxies that served as the source of new stars. Astronomers’ hopes for further research to get closer to answering the eternal question of the origin of the Universe remain high.
