Approximately 12 billion years ago, a small galaxy named LKH collided with the young Milky Way, merging with it. NASA's Hubble Space Telescope has recently provided compelling evidence of this celestial event through its analysis of globular star clusters. The discovery, published in the journal Nature Astronomy, offers a glimpse into the early phases of our galaxy's evolution.
The findings have expanded our understanding of the Milky Way's history by extending it 1.8 billion years further back in time than previous records. This groundbreaking discovery was unveiled on August 17, 2026, through a NASA Hubble Space Telescope artist's concept released by the Space Telescope Science Institute.
