Description

This object, which extends across the entire field of view of this image and beyond, is located approximately 100,000 light years from Earth. In the night sky, this star cloud appears about nine times larger than the full Moon. It is the densest concentration of individual stars in the night sky. It is an interesting object because, unlike other similar Messier objects, the star cloud is not a single star cluster. Instead, it is comprised of many thousands of stars seen through a unusually clear window in our galaxy's dust lanes. From a dark sky location, it is easily located with the unaided eye as a large hazy patch in the northern portion of the constellation of Sagittarius in the southern summer sky. It is a perfect object to see with binoculars, since it is so huge. The star cluster which stands out in the lower center of this image is NGC 6603, a faint open cluster of about 30 stars, located in the brightest region of the star cloud.
