Encyclopedic overview
Map showing the location of NGC 6369 Little Ghost Nebula, also known as NGC 6369, is a planetary nebula in the constellation Ophiuchus. It was discovered by William Herschel in 1784.
Round and planet-shaped, the nebula is also relatively faint. The high energy radiation from the central white dwarf causes the surrounding nebula to emit light. The nebula's main ring structure is about a light-year across and the glow from ionized oxygen, hydrogen, and nitrogen atoms are colored blue, green, and red respectively.
