NASA's Spirit rover found a new class of water-affected rock, while its twin, Opportunity, finished inspecting its own heat shield and set a new martian driving record.
The candles are lit, the champagne is on ice. All you need now are flowers and a ring.
It was music to the ears of physicists at the University of California, Berkeley, when they forced liquid helium-4 through thousands of tiny holes and heard a whistling sound.
Strong westerly winds buffeted the Huygens probe as it descended through Titan's upper atmosphere last month, according to NASA-led observations.
Colorful new images from the Cassini spacecraft show that Saturn's northern hemisphere has a case of the blues.
Moons circle planets, and planets circle stars. Now, astronomers have learned that planets may also circle celestial bodies almost as small as planets.› View This Video
NASA astronomers using the Keck I telescope in Hawaii are learning much more about a strange, thermal "hot spot" on the tip of Saturn's south pole.
Newly released imagery from three NASA spaceborne instruments sheds valuable insights into the Indian Ocean tsunami.
Opportunity has found an iron meteorite, the first meteorite of any type ever identified on another planet.
NASA Administrator Sean O'Keefe today offered congratulations to the European Space Agency (ESA) on the successful touchdown of its Huygens probe on Saturn's moon Titan.
NASA's Deep Impact spacecraft is out of safe mode and healthy, and on its way to an encounter with comet Tempel 1 on July 4, 2005.
NASA's Deep Impact spacecraft began its 431 million kilometer (268 million mile) journey to comet Tempel 1 today at 1:47:08 p.m. EST.
A new striking image from the infrared telescope shows a vibrant cloud called the Trifid Nebula dotted with glowing stellar "incubators."
For the first time, orbiting satellites have observed and measured a major tsunami event in open ocean, the Indian Ocean tsunami that resulted from the magnitude 9 earthquake southwest of Sumatra on December 26.
Astronomers have numerous technical terms and numbering systems for describing the universe, but one type of mysterious object has yet to be classified. They are called blobs.
NASA scientists using data from the Indonesian earthquake calculated it affected Earth's rotation, decreased the length of day, slightly changed the planet's shape, and shifted the North Pole by centimeters.
Astronomers say a dusty disc swirling around the nearby star Vega is bigger than earlier thought.
Even as the Spirit and Opportunity rovers complete a year of successful operation on Mars, the next major step in Mars Exploration is taking shape with preparation of NASA's Mars Reconnaissance Orbiter for launch in just seven months
Images returned by NASA's Cassini spacecraft cameras during a New Year's Eve flyby of Saturn’s moon Iapetus show startling surface features that are fueling heated scientific discussions about their origin.
Culminating more than four years of processing data, NASA and the National Geospatial-Intelligence Agency have completed Earth's most extensive global topographic map.
