Cosmic Mystery: Massive Galaxy Defies Dark Matter

Astronomers have discovered a massive galaxy, NGC 1277, that appears to have little or no dark matter, challenging current cosmological models. The team measured the mass distribution of the galaxy and found that dark matter could not account for more than 5% of its mass, and there may be no dark matter at all. This contradicts the standard model of cosmology, which predicts that dark matter should account for at least 10% of galaxies as massive as NGC 1277. Further observations and investigations are planned to understand this discrepancy and its implications for our understanding of dark matter and gravity.
