A "one-armed" barred spiral galaxy surrounded by a prominent star-forming ring. Chandra's X-ray data (magenta) pinpoints several bright X-ray sources, likely caused by growing black holes, embedded within the sweeping optical disk (soft blue and white) captured with the Mt. Lemmon Observatory. Galaxies with unusual single arms can offer a window into how the gravity from a passing galaxy can trigger bursts of star formation.
