International team of scientists discovered previously unknown mature galaxies in the early universe, which calls into question the existing models of cosmology. This groundbreaking discovery was made using data collected by the James Webb Telescope, which is equipped with infrared sensors capable of detecting the light emitted by the oldest stars and galaxies.

Newly discovered mature galaxies

Astronomers noticed six previously unknown galaxies that were as massive as our Milky Way, about 100 billion times the mass of the Sun. These galaxies are about 500-700 million years old from the Big Bang, which is considered the dawn of the Universe. According to the existing models of cosmology, space objects simply would not have had enough time to grow so much in such a short period of time by cosmic standards. This discovery is so stunning that astrophysicists began to look for an error in their work.

Additional research

Joel Ledge, an astrophysicist at the University of Pennsylvania who participated in the study, said, “These objects are much more massive than anyone expected. We thought we would find only tiny, young baby galaxies, but we found galaxies as mature as ours, in a period that is considered the dawn of the Universe. According to current theories, this is not possible at all.”

Scientists are conducting additional research to finally verify the truth of the facts. If everything is confirmed, the doctrine of the Universe and the existing knowledge about the formation of galaxies (or black holes) will be revised and changed. It’s worth noting that this is the first set of data collected by the James Webb Telescope, which was launched in 2021, and it allows us to look back almost to the beginning of the formation of the Universe, about 13.5 billion years ago.
