At the end of their lives, low-mass stars expand in size and become red giants. Then they shed their outer layers and become planetary nebulae. The image of NGC 2440, a planetary nebula, is on the first page of the lithograph. Background information about the life cycle of stars is on the second page. The lithograph includes a Level One Inquiry activity entitled “In Search of … Stellar Death,” in which students learn to determine the end of the life cycles of different types of stars.
