This filament is adjacent to the Perseus–Pegasus Filament.. University of Paris-Saclay cosmic cartographer Daniel Pomarede, one of the study’s lead authors, explained “One might wonder how such a large and not-so distant structure remained unnoticed.

The new 3D map developed by Tully and colleagues shows that the Milky Way galaxy resides in the outskirts of the Laniakea Supercluster, which is about 520 million light-years wide. (Image credit: SDvision interactive visualization software by DP at CEA/Saclay, France)Two views of the Laniakea Supercluster, a massive collection of galaxies that contains Earth's Milky Way galaxy and many others, are shown in these computer-generated images. We are early explorers of the cosmos, extending our maps into unknown territory,” described Tully.Throughout the last 40 years, there has been a growing appreciation of patterns in the distribution of galaxies in the Universe, reminiscent of geographic features like mountain ranges and island archipelagos. "We live in the Local Group, which is part of the Local Sheet next to the Local Void — we wanted to come up with something a little more exciting than 'Local,'" Tully told Space.com.This supercluster also includes the Virgo cluster and Norma-Hydra-Centaurus, otherwise known as the Great Attractor. According to the new map, Earth's galaxy lives near the edge of the Laniakea supercluster, which measures 500 million light-years in diameter and includes roughly 100,000 galaxies.
In 2014, the team mapped out the Laniakea Supercluster, the bundling of a hundred thousand galaxies over an even larger region, spanning 500 million light years. The concentration at the South Pole lies at a distance of 500 million light years. "We probably need to measure to another factor of three in distance to explain our local motion," Tully said.
For the past decade, an international team of astronomers, led in part by The South Pole Wall lies immediately beyond the Laniakea Supercluster, wrapping the region like an arm. The South Pole Wall is as large as the Sloan Great Wall, one of the largest structures known … Future US, Inc. 11 West 42nd Street, 15th Floor,
We have found it thanks to its gravitational influence, imprinted in the velocities of a sample of galaxies.”Astronomers map massive structure beyond Laniakea SuperclusterVisualizing galaxy orbits in the local superclusterUH astronomer and team map vast void in cosmic neighborhood "We might find that we have to come up with another name for something larger than we're a part of — we're entertaining that as a real possibility. What we have mapped stretches across the full domain of the region we have surveyed. The large size and low density of superclusters means that they, unlike clusters, expand with the Hubble expansion.

Scientists even have a name for the colossal galactic group: Laniakea, Hawaiian for "immeasurable heaven. The name is meant to honor Polynesian navigators who used their knowledge of the heavens to make long voyages across the immensity of the Pacific Ocean. Along the arm, galaxies are slowly moving toward the South Pole, and from there, across a part of the sky obscured from Earth by the Milky Way toward the dominant structure in the nearby universe, the Shapley connection.“We wonder if the South Pole Wall is much bigger than what we see.
A new cosmic map is giving scientists an unprecedented look at the boundaries for the giant supercluster that is home to Earth's own Milky Way galaxy and many others.
A supercluster is a large group of smaller galaxy clusters or galaxy groups; it is among the largest known structures of the universe.
The densest part of it lies in the direction of the Earth’s South Pole, inspiring the name.
[The name Laniakea was suggested by Nawa'a Napoleon, who teaches Hawaiian language at Kapiolani Community College in Hawaii. "We have a new way of defining large-scale structures from the velocities of galaxies rather than just looking at their distribution in the sky," Tully said.The new 3D map developed by Tully and colleagues shows that the Milky Way galaxy resides in the outskirts of the Laniakea Supercluster, which is about 520 million light-years wide.
