NGC 3521 Galaxy in Leo


NGC 3521 is a flocculent spiral galaxy located around 26 million light-years away from Earth in the constellation Leo. The galaxy extends some 50,000 light-years, it features characteristic patchy, irregular spiral arms laced with dust, star forming regions, and clusters of young, blue stars. This deep image also finds NGC 3521 embedded in gigantic bubble-like shells. The shells are likely tidal debris, streams of stars torn from satellite galaxies that have undergone mergers with NGC 3521 in the distant past.
