• Named after Hindu deities, these streams are remnants of galaxies that merged with an early version of the Milky Way over 12 billion years ago.
• The discovery helps astronomers understand the Milky Way's growth from its initial stages to its current spiral structure.
• Shiva and Shakti's stars are among the oldest in the galaxy, providing insights into the early universe's chemical composition and stellar evolution.
• Future observations by Gaia are expected to unlock more secrets about the Milky Way's infancy and its various merger events.
