NGC 6559 is a star-forming region located at a distance of about 5000 light-years from Earth, in the constellation of Sagittarius, showing both emission (red) and reflection (bluish) regions. NGC 6559 is relatively small at only a few lightyears across.[4] The nebula is found within Sharpless 29, an irregular H II region.[5]
