Astronomers have discovered the earliest "building blocks" of the Milky Way galaxy, named 'Shakti' and 'Shiva', dating back 12-13 billion years. These stellar groups offer insights into the galaxy's formation, akin to finding traces of an initial settlement that grew into a large city. 'Shakti' and 'Shiva' were identified by analyzing stellar datasets, revealing stars from merging galaxies with specific energy and angular momentum signatures. This discovery sheds light on the Milky Way's growth through merging with smaller galaxies, enhancing our understanding of its formation.
