NGC 3521 – The Bubble Galaxy

NGC 3521, also known as the Bubble Galaxy, is located about 35 Million light-years away in the constellation Leo. The galaxy has patchy, irregular spiral arms with dust, pink star forming regions and clusters of young blue stars. An interesting aspect of NGC 3521 is the bubble-like appearance that surrounds the core. These shells are likely tidal debris, streams of stars torn from satellite galaxies that have undergone mergers with NGC 3521 in the distant past.
