Discover Laniakea - the incomprehensibly vast supercluster that is our galaxy's TRUE home! This cosmic structure contains 100,000 galaxies spanning 500 million light-years, all being mysteriously pulled toward "The Great Attractor" at its center. Learn how scientists discovered this brain-like structure by mapping 8,000 galaxies and revealed that our Milky Way is just one tiny speck in this immense cosmic web.
Journey from Earth through our solar system, past billions of stars in the Milky Way, beyond the Local Group, through the Virgo Supercluster, and finally witness the mind-blowing scale of Laniakea. Understand the cosmic battle between gravity and expansion, explore the four main branches of this supercluster, and investigate the mysterious Great Attractor that defies cosmic expansion by pulling entire galaxy clusters toward it.
