LOS ANGELES - It may take much longer than scientists have thought for violent turbulence to turn grains of space dust into new planets.    A NASA telescope recently discovered evidence that the most violent part of the process in forming an Earth-sized planet - the collisions between colossal chunks of rock - may last hundreds of millions of years instead of 10 million years, scientists said Monday at NASA's Jet Propulsion Laboratory in Pasadena, Calif...
