They discover a new giant galaxy cluster with a mass of 10,000 trillion times the mass of the Sun | Sciences

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.
