"name": "An artist's view of Ho'oleilana. The three-dimensional shell enclosed by the Baryon Acoustic Oscillation is colorized in reddish/orange/brown color and enhanced to capture its content in terms of galaxies and to expose how it is encapsulated in the larger structure of the Cosmic Web. Galaxies are shown as luminous tiny specks. The Cosmic Web is represented as the blueish filamentary maze. This view also exposes the other structures discovered by the Cosmicflows research program: Laniakea our Home supercluster of galaxies; the South Pole Wall, a giant filament of the cosmic web that embraces the sourthernmost frontiers of Laniakea; the Dipole Repeller and the Cold Spot Repeller, two underdense regions presumably associated to two giant cosmic voids.\n\nCredits: Frédéric Durillon, Animea Studio; Daniel Pomarède, IRFU, CEA University Paris-Saclay.
