"Scientists Name Milky Way Galaxy's Earliest Building Blocks Shakti and Shiva"

Astronomers have identified the earliest "building blocks" of the Milky Way galaxy, naming them Shakti and Shiva, which formed 12-13 billion years ago. These groups of stars are believed to have originated from merging galaxies and exhibit distinct energy and angular momentum signatures. The stars are low in metal content, indicating their formation a long time ago, and are considered potential ancestors of the Milky Way. The research, based on data from the Gaia satellite and the Sloan Digital Sky Survey, sheds light on the galaxy's early formation.
