NGC 6749 is an open star cluster located in the constellation Aquila. It was discovered by the astronomer William Herschel in 1784 and is situated approximately 3,500 light-years away from Earth. The cluster contains several hundred stars, which are relatively young and share a common origin. The stars in NGC 6749 are loosely bound by gravity, making the cluster less dense than globular clusters. It is estimated to be around 100 million years old, showcasing a mix of bright and dim stars. Observations of this cluster help astronomers understand stellar evolution and the dynamics of star formation.
