NASA's rovers keep rolling toward fresh discoveries. The Mars Exploration Rover Opportunity has found an iron meteorite, the first meteorite ever identified on another planet, according to officials with the Jet Propulsion Laboratory (JPL) in Pasadena. Spectrometers on Opportunity determined that th...
A new study by Canadian researchers indicates a woman's chance of breast cancer returning after surgery is significantly reduced by following up with radiation therapy and tamoxifen. The study, published in the New England Journal of Medicine, was attempting to determine if women with low-risk breas...
A team of astronomers has announced the discovery of some of the smallest planets yet detected beyond our solar system: two worlds that represent a new category of extra-solar planets. Each of newly discovered planets is roughly comparable to the planet Neptune in our own solar system, says Geoffrey...

In a dramatic ending that marks a beginning in scientific research, NASA's Genesis spacecraft is set to swing by Earth and jettison a sample return capsule filled with particles of the Sun that might ultimately tell us more about the genesis of our solar system. "The Genesis mission -- to capture a ...
Scientific findings from the NASA rover Spirit's first three months on Mars will be published Friday, marking the start of a flood of peer-reviewed discoveries in scientific journals from the continuing two-rover adventure. Researchers using Spirit's toolkit of geological instruments from early Janu...
As winter approaches on Mars, NASA's Opportunity rover continues to inch deeper into the stadium-sized crater dubbed "Endurance." On the other side of the planet, the Spirit rover found an intriguing patch of rock outcrop while preparing to climb up the "Columbia Hills" backward. This unusual approa...
Francis Crick, who helped discover the double helix shape of DNA along with James Watson, has died at the age of 88, his family said on Thursday. Crick died at Thornton Hospital in San Diego where he had been battling colon cancer. British-born Crick won the Nobel Prize for his work on DNA's structu...
The Cassini spacecraft successfully performed a critical six-minute trajectory correction maneuver May 27th to put it on course with its first encounter, Saturn's outermost moon Phoebe, set for June 11th. The spacecraft is operating normally and is in excellent health. "The maneuver is very critical...
NASA's solar-powered Mars Exploration Rover Opportunity is beginning on Thursday what controllers expect to be frequent use of an overnight "deep sleep" mode to stretch the robot's power supply. Opportunity has managed only one to two hours of activity on many recent days while it has been examining...
