Astronomers using W. M. Keck Observatory on Maunakea, Hawaiʻi Island, have discovered the third known galaxy apparently lacking dark matter, part of a strange linear structure that may have formed during a violent collision between galaxies.
Nature Astronomy, Published online: 09 June 2026; doi:10.1038/s41550-026-02902-w The collective dataset of APOGEE and LAMOST reveals that the Milky Way Galaxy has a U-shaped stellar age profile extending to 20 kpc. Radial migration likely plays a key role in expanding the Galactic disc far beyond its local star formation regime.
