A. Begin by projecting an image of the Cosmic Cliffs of the Carina Nebula found at SophiaOnline.org/CosmicCliffs. For added effect and to help students focus on the stunning image, consider making your room as dark as possible by turning out the lights and closing window shades. Give your students a few moments to observe the projected image. Then, ask your students how the image makes them feel. Accept reasoned answers. B. Next, explain that the image is of the Cosmic Cliffs of the Carina Nebula, around 7,600 light years away. A nebula is a gigantic cloud of gas and dust between stars in which new stars are formed. Observable by the naked eye in the southern sky, the Carina Nebula was first discovered in 1752, and spans a region of the Milky Way Galaxy (our own galaxy) that is over 300 light-years. The region of the nebula referred to as the Cosmic Cliffs was first observed in 1826. The cliff-like appearance of the region is formed by intense radiation produced by newly formed stars eroding the walls of the nebula. Our ability to visualize this stunning phenomenon has improved over the years. The Hubble Space Telescope, launched into low Earth orbit in 1990, has provided many images of the nebula and the Cosmic Cliffs which have helped scientists learn more about how stars are born. C. Continue to explain that the image we are contemplating of the Cosmic Cliffs of the Carina Nebula comes from the new James Webb Space Telescope, which was launched into deep space (about one million miles from Earth) on December 25, 2021. The James Webb Space Telescope is the largest optical telescope in space and is outfitted with four different infrared instruments and a 6.5-meter primary mirror, allowing it to observe a much larger segment of the infrared spectrum and area of space than the Hubble Space Telescope. These improved observation instruments, combined with its deeper location in space, should result in vastly clearer images (100 times more powerful) that reveal previously invisible details and a significantly improved ability to collect data about what is being observed. The first test images from the James Webb Space Telescope were released by NASA on July 12, 2022 and have awed the world. D. Arrange your students into small groups and distribute to them copies of Handout A: Cosmic Cliffs. (Note: You may consider printing the handout double-sided and laminating them.) Continue to project the image of the Cosmic Cliffs. E. Have your students discuss the image together in their groups using the discussion questions. F. When they have finished discussing, call on groups to share about their discussions. Allow the conversation to go in unexpected directions. If your students have access to computers or tablets, consider sharing with them the comparison images found at SophiaOnline.org/WebbCompare as part of their discussion. Give them time to move the sliders on the different images to compare the older images from the Hubble Space Telescope with the new ones from the James Webb Space Telescope.Activity Instructions
Here you may consider projecting the comparison image of the Cosmic Cliffs of the Carina Nebula, found at SophiaOnline.org/WebbCompare, that allows you to move a slider between a Hubble Space Telescope image and a James Webb Space Telescope image of the same region, demonstrating the increased power of the new telescope.Lesson Extension
