Astronomen ontdekken Quipu – de grootste enkelvoudige structuur in het bekende heelal

Astronomen beweren dat het onlangs gevonden Quipu, een superstructuur waarin sterrenstelsels zich groeperen in clusters en clusters van clusters, qua lengte de grootste bekende structuur in het heelal is.

#DidYouKnow: A #Supercluster is a large group of smaller galaxy clusters or galaxy groups; they are among the largest known structures in the universe.

The #MilkyWay is part of the Local Group galaxy group (which contains more than 54 galaxies), which in turn is part of the Virgo Supercluster, which is part of the #Laniakea Supercluster.

The number of superclusters in the observable universe is estimated to be 10 million.

These two covers do get along together quite nicely!

☑️ nature.com/nature/volumes/513/
☑️ nature.com/natastron/volumes/8

A cover of the Nature Journal, dated 4 September 2014, volume 513, issue number 7516, featuring a colorful map of the basin of attraction inside which our galaxy the Milky Way is located. This structure is roughly shaped like a heart, inside which thousands of very thin flowlines are seen converging onto a unique attractor. A particular spot in the periphery of this object is pinpointed with a label that reads "YOU ARE HERE". Outside of this structure, more flowlines converge on separate, neighbor attractors. White speckles peperred across the whole scene represent positions of galaxies. A title reads Laniakea, with a subtitle reading The galaxy supercluster that includes the Milky Way. Three other research papers in various science areas are mentioned in the lower section of the cover. Credits: Cover art: Mark A. Garlick / source: Daniel Pomarède.A cover of the Nature Astronomy journal, dated December 2024, Volume 8, issue number 12, featuring a three-dimensional visualization of the cosmic velocity field inferred from the Cosmicflows-4 catalog of galaxies' distances and velocities. This map spans two billion lightyears from top to bottom. The velocity field is mapped by means of tens of thousands of very thin streamlines, seeded at the positions of the catalog's galaxies. Streamlines are shown white and semi-transparent, against a black background. They exhibit a very complex pattern with multiple attractors, seen as points of convergence of the lines. A text reads Galaxies from wherever flock together. Credits: Image: Daniel Pomarède, Institut de Recherche sur les Lois Fondamentales de l’Univers, CEA, Université Paris-Saclay.

We Are Here

a beautiful visualization of Laniakea, our Home supercluster of galaxies, produced by Félix Pharand-Deschênes

A rendering of the three-dimensional envelope delineating the basin of attraction inside which our galaxy the Milky Way is located. The envelope is rendered with a semi-transparent blueish surface inside which are displayed thousands of very thin flowlines rendered in gold color, that are seen converging onto a unique attractor. A particular spot in the periphery of this object is pinpointed with a label that reads "WE ARE HERE". The scene is rendered against a colorful background image of a numerical simulation of the cosmic web, made of filaments, voids and knots, typical of the distribution of matter on cosmological scales. This visualization is entitled "The Laniakea Supercluster" and a text reads "Among the largest known structures in the Universe, superclusters are large groups of smaller galaxy clusters. Our galaxy, the Milky Way, is part of the Local Group, which itself is part of the Virgo Supercluster, which in turn belongs to the Laniakea Supercluster. The Laniakea Supercluster extends more than 500 million light-years and contains the mass of hundred million billion stars, grouped in over 100,000 large galaxies."
