Abell 754 is a galaxy cluster in the constellation Hydra that was formed from the collision of two smaller clusters. This collision, which began about 300 million years ago, is ongoing, and the system is still disturbed. Eventually, the cluster will reach a level of equilibrium in a few billion years.
