Saturn Giant Ring

Saturn Giant Ring
This artist's rendering released by NASA's Jet Propulsion Laboratory on Tuesday Oct. 6, 2009 shows the biggest but never-before-seen ring around Saturn, spotted by NASA's Spitzer Space Telescope. The inset shows an enlarged image of Saturn, as seen by the W.M. Keck Observatory at Mauna Kea, Hawaii, in infrared light. The bulk of the ring material starts about six million kilometers (3.7 million miles) away from the planet and extends outward roughly another 12 million kilometers (7.4 million miles). The newly found ring is so huge it would take 1 billion Earths to fill it, JPL said. (AP Photo/Artist's Rendering courtesy NASA's Jet Propulsion Laboratory)
