Hubble Caldwell 29
Caldwell 29, also known as NGC 5005, is a spiral galaxy that likely harbors a supermassive black hole at its heart. The galaxy has a feature called a low-ionization nuclear emission-line region (LINER) nucleus, which means the gas at the center of the galaxy is emitting light at certain wavelengths that indicates a source of energy is removing electrons from the atoms in the gas (“ionizing” it).
