Two ancient star streams that built early Milky Way galaxy found

·1 min

Astronomers have used the Gaia space telescope to discover two ancient star streams named Shakti and Shiva. These star streams are believed to be remnants of galaxies that merged with an early version of the Milky Way over 12 billion years ago. The structures are older than the Milky Way’s spiral arms and central disk. Studying these star streams could provide insights into the early days and evolution of the Milky Way and other galaxies. The Gaia space telescope has been instrumental in uncovering previously unknown structures in the Milky Way and providing data on stars’ positions, distances, and movements.
