Do you know what big galaxies mean? Big galaxy clusters! 💫 Two enormous galaxies captured by NASAHubble Space Telescope neighbor each other approximately 350 million light-years away. The galaxy on the left is a lenticular galaxy, a galaxy type that sits between the more familiar elliptical and spiral varieties. The galaxy on the right, is a spiral galaxy facing side-on. These two galaxies, among thousands, are members of the Perseus galaxy cluster. The Perseus galaxy cluster is one of the most massive objects known in the universe! This larger-than-life cluster is named after a major figure in Greek mythology – Perseus, a valiant warrior who possessed some powerful weapons – including the head of the Gorgon Medusa, which had the capability to turn everything to stone.
