An artistic concept released on 17 August 2026 shows a collision between our Milky Way galaxy and a dwarf galaxy known as LKH that occurred approximately 12 billion years ago.
A study of data from NASA's Hubble Space Telescope, recently published in the journal Nature Astronomy, presents conclusive evidence of a dwarf galaxy merging with the young Milky Way in the earliest phases of its evolution.
The discovery extends our knowledge of our galaxy's history 1.8 billion years further back in time than was previously known.
