Exploring Laniakea: The Immeasurable Cosmic Supercluster

🌌Laniakea is a massive supercluster of galaxies, comprising hundreds of clusters and spanning over 100 million light-years.

🌟The Milky Way is located on the outskirts of Laniakea, being drawn towards the dense center known as the Great Attractor.

🌠Scientists have used the motions of galaxies to map cosmic flows and determine the distribution of matter in the universe with unprecedented detail.

🔭Super clusters are the largest structures in the universe, consisting of densely packed galaxies surrounded by vast cosmic voids.

🌐Laniakea provides a clearer understanding of the cosmic web and how neighboring structures share boundaries.

What is Laniakea?

—Laniakea is a supercluster of galaxies, including our Milky Way, that spans over 100 million light-years and consists of hundreds of clusters.

How do scientists map cosmic flows?

—Scientists map cosmic flows by studying the motions of galaxies and determining which are being pulled towards or away from us, allowing them to create a map of the distribution of matter in the universe.

Where is the Milky Way located in Laniakea?

—The Milky Way is located on the outskirts of Laniakea and is being drawn towards the Great Attractor, a dense center within the supercluster.

What are super clusters?

—Super clusters are the largest structures in the universe, consisting of densely packed galaxies surrounded by cosmic voids. They can span hundreds of millions of light-years.

What does Laniakea reveal about the cosmic web?

—Laniakea provides a clearer understanding of the cosmic web by defining the boundaries where neighboring structures share apart, allowing scientists to redefine and map the supercluster more accurately.
