The orbiting James Webb telescope has photographed and studied the spectra of two ancient galaxies for the first time, the Astrophysical Journal Letters reported.
According to the publication, the telescope photographed them approximately 360 and 450 million years after the Big Bang. As scientists note, the first galaxies appeared in the universe about 300-400 million years after the Big Bang, when its matter had time to cool to temperatures where cold gas clouds with stars rising could form.
This galaxy is located about 300 million light-years from Earth in the constellation Hydra. Its core shines particularly brightly, and its light is emitted mainly not by stars, but by hot gas and dust. The core of this galaxy is active and has a black hole inside. It attracts the material and forms around itself an accretion disk that heats the gas due to compression.
