NASA_Voyager.sff.jpg
FILE - This undated file artist's rendering shows one of NASA's twin Voyager spacecraft. NASA says the long-running Voyager 1 spacecraft hurtling toward the edge of the solar system has reached another milestone. Since 2004, the unmanned probe has been exploring a region of space where the solar wind slows abruptly and crashes into the thin gas between stars. NASA said Monday that recent readings show the solar wind has slowed to zero, meaning the spacecraft is getting ever closer to the solar system's edge. (AP Photo/NASA, File)

Saturn_Rings.sff.jpg
This image provided by NASA, taken Oct. 6, 2004, by the Cassini Saturn Probe, shows the planet Saturn and its rings. One of the most evocative mysteries of the solar system, where Saturn got its stunning rings, may actually be a case of cosmic murder with an unnamed moon of Saturn, that disappeared about 4.5 billion years ago, as the potential victim. Suspicion has fallen on a disk of hydrogen gas, that surrounded Saturn when its dozens of moons were forming, but has now fled the scene. And the cause of death? A possible forced plunge into Saturn.
