Djorgovski 1 is a globular cluster discovered in 1986 by George Djorgovski who was looking for possible obscured globular clusters using the IRAS Point Source Catalog.[3] Studies show that its stars are "metal-poor" - they contain hydrogen and helium but little else. Djorgovski 1 is actually one of the most metal-poor clusters in the inner galaxy.[4]
