NGC 3521 is a flocculent (patchy-armed) spiral galaxy located in the constellation Leo, approximately 26–40 million light‑years from Earth. It spans about 50,000 light‑years and is viewed nearly face‑on. The galaxy features a soft, “woolly” appearance due to its discontinuous spiral arms, with regions of active star formation spread throughout.
