New research conducted using data from the Hubble Space Telescope has provided compelling evidence of an ancient galactic merger. Approximately 12 billion years ago, a dwarf galaxy designated LKH collided with the young Milky Way and ultimately merged with it, becoming part of its structure. Scientists reached this conclusion by analyzing globular star clusters—dense groups of stars that are considered among the oldest objects in the universe. The characteristics of these clusters, including their chemical composition and orbital motion, allowed researchers to reconstruct the merger's history and determine the origin of part of our galaxy's stellar population. This discovery deepens our understanding of the Milky Way's evolution and confirms the theory that large galaxies like ours formed by absorbing smaller galactic systems over billions of years. The presented artistic concept illustrates how this ancient collision might have looked, occurring in the earliest stages of our galaxy's formation.
