Unlike galaxy clusters, superclusters are too big to be bound strongly by gravity, and there’s some debate among astronomers about how to define what a supercluster is. In the new paper ...

This visualization of the Laniakea supercluster, which represents a collection of more than 100,000 ... The impressively huge galaxy cluster MACS J1149.5+223, ...

If you want to pinpoint your place in the universe, start with your cosmic address. You live on Earth->Solar System->Milky ...

Laniakea, described in the journal Nature, stretches some 500 million light years across and holds 100,000 galaxies with the mass of a hundred million billion suns.

Our own supercluster, Laniakea, consists of approximately 100,000 galaxies, more than 10 times richer than the largest known clusters. Yet these superclusters only appear to be structures.

A new map of a giant group of galaxies known as the Laniakea Supercluster is giving scientists a revealing glimpse of our Milky Way galaxy's home in the universe. See it here.

Norma, Hydra, Centaurus, Virgo, Ophiuchus, A2870, A3581 and A3656 are individual clusters of galaxies embedded within the Laniakea supercluster. Shapley, Hercules, Coma and Perseus–Pisces are ...

"The Laniakea supercluster encompasses 13 major galaxy clusters, including both the Virgo cluster and the Great Attractor -- a giant mass comprising both the Norma galaxy cluster and the Hydra ...

There are lots of lines in our planet's cosmic address: Earth, the solar system, the Milky Way galaxy, the Local Group of galaxies, and the Virgo Cluster of galaxy groups. Now astronomers are ...
