"Discovery: Ancient Building Blocks Shakti and Shiva Found in Milky Way"
Scientists using the Gaia space telescope have identified two ancient star groupings, named Shakti and Shiva, which are believed to be among the Milky Way Galaxy’s earliest parts and may be the remains of two galaxies that combined 12 billion years ago. These structures offer new insights into how our galaxy formed and are made up of stars containing similar chemicals, believed to have formed 12 to 13 billion years ago. The discovery provides valuable information about the early stages of the Milky Way's formation and its evolution.
