Three Galaxy Pairs

NASA

0 views

  • The Centaurus Galaxy Cluster contains multiple distinct pairs of galaxies, each exhibiting unique gravitational and evolutionary states.
  • These pairs illustrate a range of interactions, from non-interacting systems to active mergers.

Featured Galaxy Pairs

  • Top Pair (Non-interacting): Includes NGC 4650A, a polar ring galaxy characterized by a blue stripe, likely formed by a historical collision.
  • Middle Pair (Apparent but not interacting): Comprised of two galaxies, including the spiral galaxy NGC 4650 which features a bright stellar bar; they appear linked but their relative speeds suggest they are not gravitationally interacting.
  • Bottom Pair (Actively interacting): Comprised of NGC 4622A and NGC 4622B; these galaxies are currently interacting and are expected to merge into a single entity in approximately one billion years.
