This image of the Ring Nebula, NGC 6720, shows the distinctive shape of the glowing remains of a Sun-like star.
Combining the visible-light views from the Hubble Space Telescope with infrared data from the ground-based Large Binocular Telescope, this composite image reveals that the nebula is more complex than astronomers previously thought.
Included is an inquiry-based classroom activity that focuses on the image and text.
This image from the Hubble Space Telescope showcases the distinctive shape of the Ring Nebula and offers the best view yet of the nebula. The observations reveal a more complex structure than previously thought. A captioned inset on the back shows the variety of shapes of planetary nebulae. Includes a classroom activity.
Teachers can use this lithograph as:
An example of a planetary nebula. Use the inquiry-based classroom activity called In Search of Planetary Nebulae Shapes that is included with the PDF lithograph.
An engagement tool in an inquiry-based lesson. Have students study the images on the lithograph. Ask them to write down any questions they have about the images. When the students are finished, their questions can be used in a variety of ways:
A content reading tool. Have students read the text on the lithograph and then write a quiz for the class.
