Hoʻoleilana

Proper noun

Ho'oleilana

1. Ho'oleilana A structure in local Universe; An assembly of superclusters and voids, forming a spherical assemblage of matter with a central peak, roughly 1-billion-lightyears across, located next to, but not containing, Laniakea, our local supercluster where the Earth is contained within. Thought to be a baryon acoustic oscillation (“BAO”), the first such discovered, and the nearest such found.
   • In any event, this apparent ring structure at a distance of ∼250 Mpc from us is one of the largest structures observed in the nearby Universe to date and links together a number of hitherto disconnected components of our cosmic neighborhood. We name this remarkable structure "Ho'oleilana."
