NASA's Cassini probe of Saturn prepares for last plunge



Miami (AFP) April 5, 2017
NASA's unmanned Cassini spacecraft is preparing for its final plunge into Saturn later this year, after two decades of helping Earth-bound scientists make new discoveries about the sixth planet from the Sun and its mysterious rings. For what NASA has described as Cassini's "grand finale" as it runs short on fuel, the spacecraft will soar through a 1,500-mile-wide (2,400-kilometer) gap between Saturn and its rings. Its goal is to sample Saturn's atmosphere and particles coming from the main ring ... read more

Neptune's movement from the inner to the outer solar system was smooth and calm
Washington (UPI) Apr 4, 2017
New research suggests Neptune's transition from the inner to the outer solar system was relatively slow and steady. The clues to the nature of Neptune's ancient move were discovered in the Kuiper belt, a massive ring of space debris - mostly icy fragments - lying beyond Neptune's orbit. Most of the millions of objects in the Kuiper belt are red in color, but a minority of objects are ... more
