NGC 6690 is a barred spiral galaxy located approximately 100 million light-years away in the constellation Hercules. It is notable for its bright core and distinct spiral arms, which are characteristic features of spiral galaxies. NGC 6690 is classified as a type SBc galaxy, indicating its intermediate structure between spiral and barred spiral types. This galaxy is part of a group of galaxies known as the Hercules Cluster. Observations of NGC 6690 have provided valuable insights into galaxy formation and evolution, particularly in understanding the dynamics of spiral structures. Its distance and brightness make it a subject of interest for astronomers studying the universe.
