The Milky Way formed approximately 13.6 billion years ago, not long after the Big Bang. Its age is inferred from the ages of the oldest stars within the galaxy, which are around 13.8 to 13.9 billion years old. Over its long history, the Milky Way has undergone numerous evolutionary processes, including star formation, mergers with other galaxies, and interactions with dark matter.
