CCNet -- Late Quaternary Mass Extinction Was OUR Fault!

"Composite images of Saturn's rings, taken by NASA's Hubble Space Telescope, have revealed mysterious color variations that hint that the rings could be made of materials from the outer solar system. [...] This leads scientists to suspect that, unlike the moons, the rings were formed from an outer solar system object. This object, they think, careened too close to Saturn and -- like comet Shoemaker-Levy 9 in 1994 -- was torn apart by the massive planet's gravity, leaving a trail of debris."
-- Kathleen Burton, NASA Ames Research Center, 7 June 2001

"The SDSS observations also showed that the two types of asteroids are spatially separated with the inner belt of rocky asteroids centered at about 2.8 AU from the sun and the outer belt of carbonaceous asteroids centered at about 3.2 AU. This distribution has important implications for unraveling how the solar system formed and suggests that planet migrations that seem to be common in other planetary systems have not occurred in ours."
-- Tom Quinn, University of Washington, 5 June 2001
