Third Dark Matter-Deficient Galaxy DF9 Discovered Along NGC 1052 Trail
L'essentiel
- A third galaxy, DF9, has been found to be missing dark matter, joining DF2 and DF4 along the NGC 1052 trail.
- Observations suggest DF9's mass is almost entirely from its stars, challenging the assumption that galaxies are dominated by dark matter.
- This discovery strengthens the theory that a single disruptive event created these unusual galaxies.
