This composite image features a region of star formation known as the Pillars of Creation. It features x-rays from the Chandra X-ray Observatory (red and blue) and infrared image from the James Webb Space Telescope (red, green, and blue). Star formation is the topic of one of the quiz questions. Good luck! Credit: X-ray: NASA/CXO/SAO; Infrared: NASA/ESA/CSA/STScI; Image processing: NASA/CXC/SAO/L. Frattare hide caption
