NGC 3690B is a starburst galaxy located approximately 100 million light-years away in the constellation Ursa Major. It is part of a pair of interacting galaxies known as NGC 3690, which also includes NGC 3690A. The intense star formation in NGC 3690B is driven by gravitational interactions with its companion galaxy. This galaxy is notable for its high rate of star production, which is significantly greater than that of the Milky Way. Observations of NGC 3690B have revealed a rich environment of young, hot stars and the presence of various molecular gas clouds, contributing to its dynamic and vibrant nature.
