A group such as the National Astronomical Observatory succeeded in observing “Galaxy Cluster”, the oldest galaxy group ever seen 13 billion years ago, 800 million years after the birth of the universe. , Has attracted attention as an achievement that reveals part of the evolutionary process of the universe.
The Subaru Telescope successfully observed a galaxy cluster in the direction of the Whales, at a distance of 12.97 billion light years from the Earth, an additional 100 million light years from the farthest galaxies that have been found so far. In the distance.
According to groups such as the National Astronomical Observatory of Japan, when a special camera that can shoot with a wide field of view was attached to the Subaru Telescope, it was found that the area where the galaxies are densely located.
The discovered galaxy cluster is that 12 galaxies have gathered, and it is in the initial state of growing into a galaxy cluster with about 1000 galaxies. This galaxy cluster seems to have been created 13 billion years ago, 800 million years after the birth of the universe 13.8 billion years ago, and is attracting attention as a result of clarifying part of the evolutionary process of the universe .
“I was surprised that the galaxy cluster was the most important structure of the universe and already existed 800 million years after the Big Bang,” said Yuichi Harimaki, a research member of the National Research Institute of Japan. I was talking.
