Radio Astronomers Find Weird Object in Nearby Galaxy That Stands Out Against the Entire Sky

Astronomers have discovered "Punctum," a mysterious bright dot in the NGC 4945 galaxy that outshines its surroundings, including the central black hole. Located 11 million light years away, it's far more luminous than typical magnetars and most supernovae. Visible only in millimeter wavelengths, Punctum doesn't match any known cosmic object. Researchers plan to study its unusual polarization to determine its power source, highlighting that the universe can still surprise us in seemingly familiar places.
