The ring is huge, and far from the gas planet and the rest of its majestic rings. Image credit: NASA/JPL-Caltech Image 3: This diagram highlights a slice of Saturn’s largest ring. The ring (red band in inset photo) was discovered by NASA’s Spitzer Space Telescope, which detected infrared light, or heat, from the dusty ring material. Spitzer viewed the ring edge-on from its Earth-trailing orbit around the sun. Hubble image credit: NASA/ESA/STScI/AURA
