The giant structure, nicknamed King Ghidorah, has been identified 5.5 billion light-years from Earth.
About 5.5 billion light-years away, a team of Japanese astronomers has discovered a new giant galaxy cluster. It is one of the most massive structures ever identified: its main structure is there 10,000 trillion times sun block. Despite that, it’s still not as huge Inakiato which it belongs Milky Waywho has 100,000 trillion solar masses.

named b King Ghidorah Named after a fictional monster from Japanese movies, the Galaxy Supercluster contains no fewer than 19 linked galaxy clusters, spread out over an area of sky roughly the size of 15 full moons. The result has been published in the journal Monthly Notices of the Royal Astronomical Society.
Galaxy clusters, groupings of millions of galaxies, are one of the largest structures in the universe. The Milky Way, for example, is located within the constellation Virgo, but at the same time it is part of a larger group: Lainakea supercluster.
Although superclusters span an area of about 100 megaparsecs (about 500 times the size of the Milky Way), their definition itself remains fuzzy. Meanwhile, her true nature and what goes on inside her remains shrouded in mystery.

The Hyper Suprime-Cam (HSC) of the Subaru Telescope, an instrument operated by the National Astronomical Observatory of Japan (NAOJ), surveyed the universe in an area equivalent to 4,400 times the apparent size of the Moon and a depth of more than 10,000 million light-years. The high-quality imaging data obtained with this software is currently the best resource for searching for unknown superclusters of galaxies, they said in a statement.
The research team examined the total stellar mass and dark matter distribution in the largest density excesses among the nearly 100 candidate supergiant clusters, which have been detected by the same group in the past.
As a result, he discovered a structure of this type consisting of no fewer than 19 galaxy clusters centered in three dark, matter-dense regions.
Comparison with cosmological simulations indicates that it has a mass of dark matter about 10 times that of the pupal in the local universe. In addition, two supercluster-equivalent giant structures have been identified just outside the cluster, meaning the discovery may be a precursor to other massive objects in the universe.
“In fact, the probability of finding such a giant cluster, about 5.5 billion light-years away, was 50% based on the results,” says lead author Dr. Rhythm Shimakawa, project assistant professor at NAOJ. the program. We plan to further investigate the 3D structure and morphology of galaxies using instruments such as the Subaru Telescope’s Wide Field Spectrometer (PFS) and Euclid Space Telescope in the near future. ”
