A globular cluster is a tight-knit collection of many thousands, sometimes even millions, of stars born at almost the same time and place. The image of NGC 5139, a globular cluster, is on the first page of the lithograph. Background information about Omega Centauri is on the second page. The lithograph includes a Level One Inquiry activity entitled "In Search of ... Stellar Evolution," in which students research the variety of colors of stars.
