Great AttractorRegion of gravitational attraction in the local universe Hubble Space Telescope image showing part of the Norma Cluster, including the galaxy ESO 137-002 The Great Attractor is a region of enhanced gravitational attraction in the local universe. It lies in the general direction of the Norma Cluster and the Hydra–Centaurus Supercluster, approximately 150–250 million light-years from the Milky Way.
SuperclusterA supercluster is a large group of smaller galaxy clusters or galaxy groups; they are among the largest known structures in the universe. The Milky Way is part of the Local Group (containing more than 54 galaxies), part of the Laniakea Supercluster, contained within the larger Pisces–Cetus Supercluster Complex. The large size and low density of superclusters means that most of them, unlike clusters, expand with the Hubble expansion.
GalaxyA galaxy is a physical system of stars, planetary systems, stellar remnants, substellar objects, interstellar gas, dust, and dark matter bound together by gravity. The word is derived from the Greekgalaxias (γαλαξίας), meaning 'milky', a reference to the Milky Way galaxy that contains the Solar System.
Milky WayGalaxy containing the Solar SystemArtist's impression of the structure of the Milky Way based on data from the European Space Agency's Gaia telescope, including the location of the spiral arms, bar, and bulgeThe Milky Way or Milky Way Galaxy, or simply the Galaxy, is the galaxy that includes the Solar System, with the name describing the galaxy's appearance from Earth: a hazy band of light seen in the night sky formed from stars in other arms of the galaxy, which are so far away that they cannot be individually distinguished by the naked eye.
Daniel PomarèdeDaniel Pomarède (born October 3, 1971) is a staff scientist at the Institute of Research into the Fundamental Laws of the Universe, CEAParis-Saclay University. He co-discovered Laniakea, our home supercluster of galaxies, and , a spherical shell-like structure 1 billion light-years in diameter found in the distribution of galaxies, possibly the remnant of a Baryon Acoustic Oscillation.

Observable universeThe observable universe is a spherical region of the universe consisting of all matter that can be observed from Earth; the electromagnetic radiation from these astronomical objects has had time to reach the Solar System and Earth since the beginning of the cosmological expansion. The radius of this region is about 14.26 gigaparsecs (46.5 billion light-years or 4.40×10 m).

Hawaiian languagePolynesian language spoken in HawaiiHawaiian (‘ōlelo Hawai‘i, pronounced) is a critically endangeredPolynesian language of the Austronesian language family, originating in and native to the Hawaiian Islands. It is the historic native language of the Hawai‘ian people. Hawaiian, along with English, is an official language of the U.S. state of Hawaiʻi. King Kamehameha III established the first Hawaiian-language constitution in 1839 and 1840.University of Hawaiʻi at MānoaThe University of Hawaiʻi at Mānoa is a public land-grant research university in Honolulu, Hawaii, United States. It is the flagship campus of the University of Hawaiʻi system and houses the main offices of the system. Most of the campus occupies the eastern half of the mouth of Mānoa Valley on Oʻahu, with the John A. Burns School of Medicine located adjacent to Kakaʻako Waterfront Park.
