Explore the galaxies in our local universe with our ebook Summer Deep Sky. The team used radio telescopes to map the motions of a large collection of local galaxies. It’s almost perpendicular to the galactic plane of the Milky Way. Due to the nature of cosmic expansion, a galaxy recedes faster the farther away it is. These new findings help clear up the role of the Great Attractor, which is a problem that has kept astronomers busy for 30 years. Wikiquote has quotations related to:

The real number may be much larger because some of these are traversing the Zone of Avoidancemaking them essentially undetectable. You must be logged in to post a comment. The entire supercluster consists of approximately to known galaxy clusters and groups.
The new catalog reveals where the flows merge and diverge, unveiling a gargantuan structure on whose periphery the Milky Way sits. Views Read Edit View history. Galaxy superclusters Astronomical objects discovered in Laniakea Supercluster.
Nature has also created an in-depth video on the discoverywhich I recommend watching. 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. Given that Laniakea is moving toward Shapley, our supercluster might indeed be only the trunk of the elephant, Tully says.
And to extend the watershed metaphor, our Milky Way galaxy sits near the ridgeline of the continental divide between our supercluster and the neighboring Perseus-Pisces supercluster.

New Galactic Supercluster Map Shows Milky Way’s ‘Heavenly’ Home | Space
All Laniakfa About Us More. 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. Explore the galaxies in our local universe with our ebook Summer Deep Sky. Retrieved 14 March Laniaeka 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.

Laniakea: Our Home Supercluster
Have a news tip, correction or comment? 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. 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 work, published in the September 4th Natureis the first to trace our local supercluster on such a large scale. Learn how your comment data is processed.
Laniakea – Wikipedia
This computer-generated depiction of the Laniakea Supercluster of galaxies, which includes the Milky Way ,aniakea containing Earth’s solar system, shows a view of the supercluster as seen from the supergalactic equatorial plane. Scientists have created the first map of a colossal supercluster of galaxies known as Laniakea, the home of Earth’s Milky Way galaxy and many other. The videos are quite helpful in visualizing Laniakea in three dimensions. 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.

Let us know at community space. The massive structure, which the research team dubs the Laniakea Supercluster, extends more than million light-years and containslarge galaxies.
