An image from NASA's WISE (Wide-field Infrared Survey Explorer) of an area of the sky on the border of the constellations Sagittarius and Corona Australis. The wispy nebula running top to bottom of this image is a nearby star forming region which has been called the Coronet Cluster. It is located some 420 light-years from Earth, and stretches about 10 light-years across. Just to the left of center is a very different kind of star cluster. NGC 6723 is a globular star cluster located some 29,000 light-years away from Earth, and spans about 65 light-years in size
