The supergalactic plane is a reference plane in a cosmological coordinate system and passes through the Sun, the Milky Way’s center, and the center of the Virgo Cluster of galaxies. The Milky Way is at the little blue dot toward the right-hand edge of the circled region just below the reddish area, which is the Virgo Cluster. Have a news tip, correction or comment?

Farther out, the data are sparser. It has the approximate mass of 10 17 solar masses, or a hundred thousand times that of our galaxy, which is almost the same as that of the Horologium Supercluster.
Due to the nature of cosmic expansion, a galaxy recedes faster the farther away it is. From Wikipedia, the free encyclopedia. In other projects Wikiquote. Thanks for this fascinating report! Within a given supercluster, most galaxy motions will be directed inward, toward the center lanoakea mass. Retrieved 14 March In the case of Laniakea, this gravitational focal point is called the Great Attractorand influences the motions of the Local Group of galaxies, where the Milky Way galaxy resides, and all others throughout the supercluster.
A slice of the Laniakea Supercluster in the supergalactic equatorial plane. Follow-up studies suggest that Laniakea is not gravitationally bound; it will disperse rather than continue to maintain itself as an overdensity relative to surrounding areas. Superclusters are some of the universe’s largest structures and have boundaries that are difficult to define, especially from the inside.

Monthly Notices of the Royal Astronomical Society. These new findings help clear up the role of the Great Attractor, which is a problem that has kept astronomers busy for 30 years.
Laniakea: Our Home Supercluster
But the team found a way around this problem by using an analysis technique called Wiener filtering. Triangulum Australe and Norma centre. Views Read Edit View history. It also provides a physical way to define what a supercluster actually is.
Astronomy portal – Cosmology portal. Astronomy portal Cosmology portal. The supercluster is made up of aboutgalaxies with a total mass about million billion times that of the sun.
Laniakea Supercluster – Wikiquote
The scientists responsible for the new 3D map suggest that the newfound Laniakea supercluster of galaxies may even be part of a still-larger structure they have not fully defined yet.

To better define these structures, astronomers examined Cosmicflows-2, the largest-ever catalog of the motions of galaxies, reasoning that each galaxy belongs to the structure whose gravity is making it flow toward. The analysis also reveals other structures, including a separate supercluster called Perseus-Pisces and a distant concentration named Shapley, which lies about million light-years away and toward which Laniakea is moving.
In turn, these groups are part of massive clusters made up of hundreds of galaxies, all interconnected in a web supwrcluster filaments in which galaxies are strung like pearls. This computer-generated depiction of the Laniakea Supercluster of galaxies, which includes the Milky Way galaxy containing Earth’s solar system, shows a view superclustre the supercluster as seen from the supergalactic equatorial plane.
The massive structure, which the research team dubs the Laniakea Supercluster, extends more than million light-years and containslarge galaxies.
