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.

The first precise measurement of a failed star known as a brown dwarf finds the object is much more massive than theorists expected. The result challenges what astronomers&nbsp;assumed about these strange things, which straddle the mass range between huge planets and normal stars.

The Moon is getting hit by meteoroids more often than anyone expected.  That's the tentative conclusion of astronomers who recently saw two Leonids hit the Moon and explode.

Cassini&#39;s close fly-by of Titan, Saturn&#39;s largest moon, has left scientists with no clear idea of what to expect when the Huygens probe lands on the alien world, despite the amazingly detailed images they now have of the surface.

If all goes to plan, my research colleagues and I will have front row seats to spectacular New Year fireworks. These are not the artificial bangs and whistles that shoot a few hundred yards into the sky, but the awe-inspiring impact of cosmic dust moving at astronomical speeds. These bits of comet dust travel through space faster than Santa's sled, spanning the distance from Los Angeles to New York in a mere minute and a half. When they hit Earth, the impact of a grain of sand shines so brightly it can be seen for hundreds of miles around. They are called "meteors."
