Scientists have discovered the oldest swarm of galaxies in the universe



The age of the universe reaches 13.8 billion. Years ago, finding such early galaxy clusters – called protozoa – was not easy, said Huichi Harikane, a researcher at the Japan National Astronomical Observatory who led the study.

"The discovery of this proton, a system of 12 galaxies, suggests that large space structures already existed in the early stages of the formation of the Universe," Harikane said.

One of the 12 galaxies named Shimiko was discovered by the same telescope back in 2009.

"It makes sense to find prototypes near a giant object like Jimico. However, we were surprised that Shimiko was over 500 million miles from downtown. light years. It is not clear why Shimiko is not at the center of the cluster, "said Masami Ochi, another research author.

The findings of the study, he said, will help scientists better understand the relationship between swarms and huge galaxies.

The team also included astronomers from Imperial College London. The results of the study were published in the scientific journal Astrophysical Journal.
