Galactic Cluster Challenges Universe Model
Astronomers have discovered a rare group of five interacting dwarf galaxies, located 117 million light years away, challenging the prevailing Lambda cold dark matter model of the universe. These galaxies, designated D1 to D5, are aligned in a straight line and show signs of mutual tidal interactions, with some sharing a common rotational direction. This unusual configuration raises questions about galaxy formation and evolution, potentially offering new insights into cosmological history. The findings were published in The Astrophysical Journal Letters.
