Laniakea is a vast galaxy supercluster that includes our own galaxy, the Milky Way. It spans about 520 million light-years and contains over 100,000 galaxies. The name "Laniakea" means "immense heaven" in Hawaiian, reflecting its grandeur and the beauty of the cosmos. Discovered in 2014, Laniakea is part of a larger cosmic structure known as the observable universe. It helps astronomers understand how galaxies are organized and how they interact with each other. This supercluster is a reminder of the vastness of space and our place within it.
