Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.
The Dawn of the Clusters
Explanation: What did the universe look like near the beginning? This exciting photo by the Hubble Space Telescope is one of the deepest ever taken, and shows galaxies as far away as ever before photographed. The universe back then - when only one third of its present age - was a strange and violent place. Back then a large fraction of galaxies were colliding and interacting . In fact, the shapes of many galaxies in the above photo are more distorted than most nearby galaxies . At this early universe epoch many clusters of galaxies were just forming. The bright twisted group of galaxies below the photographs center contains the energetic radio galaxy 3C324.
