# Laniakea: Our home supercluster 신기하다. 아마도 우리은하 주변 은하들 수만개의 움직임을 측정해서 어느 한 지점으로 뭉치고 있는걸 발견한듯. 동영상을 잘 만들어놔서 좋다.
Laniakea: Our home supercluster
Laniakea: Our Home Supercluster of Galaxies
Explanation: It is not only one of the largest structures known -- it is our home. The just-identified Laniakea Supercluster of galaxies contains thousands of galaxies that includes our Milky Way Galaxy, the Local Group of galaxies, and the entire nearby Virgo Cluster of Galaxies. The colossal supercluster is shown in the above computer-generated visualization, where green areas are rich with white-dot galaxies and white lines indicate motion towards the supercluster center. An outline of Laniakea is given in orange, while the blue dot shows our location. Outside the orange line, galaxies flow into other galactic concentrations. The Laniakea Supercluster spans about 500 million light years and contains about 100,000 times the mass of our Milky Way Galaxy. The discoverers of Laniakea gave it a name that means "immense heaven" in Hawaiian.
