The Cassini spacecraft's mission to Saturn has revealed a new radiation belt around the ringed planet and found that lightning in its atmosphere is occurring in different patterns than it did when NASA's Voyagers flew by in the early 1980s, scientists said.

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...

A University of Colorado study has embarked on demonstrating that new planets can be found with the help of an orbiting starshade. The method has been compared to building a giant pinhole camera in space.

New observations of dust around young stars suggests collisions of large asteroid-like objects and fledgling planets are frequent. But that doesn't likely stop the formation of rocky planets like Earth, a process that may well be common, the results suggest.

By ALICIA CHANG, THE ASSOCIATED PRESS  LOS ANGELES  A provocative new study of photographs taken from orbit suggests that liquid water flowed on the surface of Mars as recently as several years ago, raising the possibility that the Red Planet could harbor an environment favorable to life.

Astronomers have found the first signature of complex organic molecules in the dust cloud around a distant star, suggesting that these building blocks of life may be a common feature of planetary systems.

In a solar system thousands of light years away, a star about half the size of our sun is being orbited by two planets that seem like smaller versions of Jupiter and Saturn, astronomers report.
