This lithograph features an image from the Hubble Space Telescope, showcasing the distinctive shape of the Ring Nebula, NGC 6720. The accompanying classroom activity, In Search of…Planetary Nebula Shapes, is a curriculum support tool designed as an introductory inquiry activity. In this activity, students will use the lithograph image and text to generate questions about planetary nebulas shapes, and then research the answers to those questions. Students will then create a presentation to demonstrate their understanding of the material.
