What's the biggest thing in the universe, besides the universe itself? Well, stars live in galaxies, and galaxies live in large collections called galaxy clusters. Astronomers can study these titanic clusters of galaxies to learn about how they grow and merge with each other to assemble the universe we live in today. Dr. Kyoung-Soo Lee takes us on a journey to the largest scales in the cosmos.
