NASA's Kepler spacecraft, which is searching for Earth-mass planets orbiting sun-like stars, is finding hundreds of candidate planets, and many more multi-planet systems than expected.
Two years into a 3-1/2-year mission, NASA’s Kepler spacecraft, hunting for planets orbiting some 165,000 stars in the constellation Cygnus, is uncovering planet candidates by the hundreds.
Many of these inhabit multi-planet systems that are unexpectedly flat – the inclination of the planets’ orbits within each of these systems are essentially the same, a feature that may hold clues about how these systems formed and evolved.
Fukushima may be in an apocalyptic downward spiral. 
Weather scientists are retracing the footprints of this week's monstrous tornadoes the way detectives would investigate a crime scene: talking to witnesses, watching surveillance video and taking the measurements of trees ripped from the ground.
In the mountains of Northern California, a field of radio dishes that look like giant dinner plates waited for years for the first call from intelligent life among the stars. But they're not listening anymore.
Mars today has a brutal environment — frigid, arid and, because of its very thin atmosphere, constantly bombarded by lethal radiation. But it was worse 600,000 years ago, according to new research that suggests the planet had a far dustier, stormier atmosphere.
It looks like a giant potato in space. And yet, the information in this model is the sharpest view we have of how gravity varies across the Earth. The globe has been released by the team working on Europe's Goce satellite.
