NGC 4535, nicknamed the "Lost Galaxy," is a large, barred spiral galaxy in the Virgo constellation, about 50 million light-years away, known for its faintness in small telescopes but revealed in stunning detail by the Hubble Space Telescope as a vibrant system with bright blue star clusters, pink H II regions, and red nebulae, indicating active star formation. Its blue spiral arms contrast with a yellower central bulge of older stars, and it's a key target for studies like the PHANGS survey, which links gas, star formation, and galactic structure.
