In a new study, researchers describe what they found in data from Cassini: a new class of space particles—submicroscopic nanograins of electrically charged dust. Such particles are believed to exist throughout the universe, and this marks the first time researchers have measured and analyzed them.
The SpaceX company made history as its Falcon 9 rocket, carrying 1,000 pounds of space station provisions in its Dragon capsule, rose from its seaside launch pad and pierced the pre-dawn sky, aiming for a rendezvous in a few days with the space station. If the mission proceeds as planned, Dragon will be the first commercial vessel to visit the space station.
Researchers at Massachusetts Institute of Technology, NASA, and elsewhere have detected a possible planet, some 1,500 light years away, that appears to be evaporating under the blistering heat of its parent star. The scientists infer that a long tail of debris is following the planet, and that this tail may tell the story of the planet's disintegration.
Shape-memory alloys are an engineer's dream, able to shape-shift spontaneously to accommodate changing operating conditions. A research team from NASA and the University of Central Florida is studying the internal mechanisms of these real-life "transformers" at the Spallation Neutron Source at Oak Ridge National Laboratory, with an eye toward increasing their use in everyday scenarios.
Scientists on a planetary-heat-seeking mission have detected the first infrared light from a super-Earth—in this case, a planet some 40 light-years away. And according to their calculations, 55 Cancri e, a planet just over twice the size of Earth, is throwing off some serious heat.
Space may be the final frontier. But often a few trips to NIST's Physical Measurement Laboratory are necessary before things can get off the ground. One recent case in point is the test of an instrument called the Extreme Ultraviolet Monitor, which will soon be heading for Mars to help answer a vexing question in planetary science: Where did the Red Planet’s once-dense atmosphere go?
A group of scientists took to the skies in a slow-moving airship Thursday in search of meteorites that rained over California's gold country last month. It's the latest hunt for extraterrestrial fragments from the April 22 explosion that was witnessed over a swath of Northern California and Nevada.
As the Boeing 747 zoomed over the Manhattan skyline Friday, onlookers gawked at the unusual sight, realizing that the smaller plane hitched to its fuselage was an actual space shuttle. The Enterprise will soon make its home in New York City, basking in retirement about the Intrepid carrier in the Hudson River.
For more than a decade, scientists debated whether a maze of valleys near the Martian equator was sculpted by ice or volcanic processes. Now, aresearcher reports finding lava flows shaped like coils of rope near the equator of Mars, the first time such geologic features have been discovered outside of Earth.
On December 24, 1968, the astronauts aboard Apollo 8 were conducting an extensive photographic survey of the moon’s surface. When they paused to take a navigation sighting, they were shocked to see the Earth “rising” above the lunar surface. Using modern imagery, NASA’s Lunar Reconnaissance Orbiter has recreated the moment, shortly before the first real photograph was taken.
Evoking memories of the earliest shuttle flights that started with a mate-demate device atop a modified jumbo jet, the space shuttle Discovery this morning departed on its final flight from Florida’s Kennedy Space Center. The Discovery was bound for Washington, where it will become a museum piece at the Smithsonian Institution.
Starting Friday, NASA’s Mars Program Planning Group began accepting ideas and abstracts online from the worldwide scientific and technical community as part of NASA's effort to seek out the best and the brightest ideas from researchers and engineers in planetary science. They hope to develop a new strategy for the exploration of Mars.
The giant explosion that gets a rocket off the ground isn't that complicated. In the case of North Korea’s failed rocket launch last week, two liquid propellants ignite when mixed. Controlling that explosion, and keeping the pointy end of the rocket pointed skyward, is what keeps engineers up at night, and is why rocket science is really, really hard.
A researcher working with images from NASA’s Solar Dynamic Observatory recently saw something he’d never seen before: a pattern of cells in the sun’s corona. Using a combination of conventional and magnetic imaging from several satellites and spacecraft, astronomer were able to build a 3D picture of what was happening on the sun’s surface.
According to NASA scientist Dr. Nicholas Schmerr, a layer of partially molten rock about 22 to 75 miles underground can't be the only mechanism that allows continents to gradually shift their position over millions of years. He contends that because his research has revealed this melt-rich layer to be spotty, another cause must exist for the movement of plates over the mantle.
New observations from a spacecraft orbiting Mercury have revealed that the tiny, pockmarked planet harbors a highly unusual interior—and the craft's glimpse of Mercury's surface topography suggests the planet has had a very dynamic history.
Published by the U.S. Geological Survey, the first fully global geologic map of Jupiter’s moon Io technically illustrates the geologic character of some of the most unique and active volcanoes ever documented in the solar system.
The International Space Station may provide the setting for a 500-day pretend trip to Mars in another few years. NASA said Tuesday that consideration is underway to use the space station as a dry run for a simulated trip to and from Mars.
Astronomers using NASA's Hubble Space Telescope have found several examples of galaxies containing quasars, which far outshine the total starlight of their host galaxies. These superbright objects contained within the galaxy act as gravitational lenses, amplifying and distorting images of galaxies aligned behind them.
General Motors (GM) and NASA are jointly developing a robotic glove that automotive workers and astronauts can wear to help do their respective jobs better while potentially reducing the risk of repetitive stress injuries.
Los Alamos National Laboratory scientists and an international research team have announced discovery of molecular oxygen ions in the upper-most atmosphere of Dione, one of the 62 known moons orbiting the ringed planet. The research was made possible by instruments aboard NASA's Cassini spacecraft, which was launched in 1997.
For the first time, researchers at Massachusetts Institute of Technology and elsewhere have detected all phases of thermonuclear burning in a neutron star. The star, located close to the center of the galaxy in the globular cluster Terzan 5, is a model burster, say the researchers.
The fastest wind ever discovered blowing off a disk around a stellar-mass black hole has been observed by a team of astronomers. Using NASA's Chandra X-ray Observatory they clocked the record-breaking super wind at about 20 million mph, or about 3% of the speed of light.
In new images from NASA’s Lunar Reconnaissance Orbiter (LRO), researchers have found what they believe is evidence of a rift valley. Small, narrow trenches called graben have been discovered in high-resolution imagery that seems to show that despite the fact the Moon is shrinking, forces are still acting that can pull it apart as well.
NASA says it still has confidence in the quality of Russia's manned rockets, despite an embarrassing series of glitches and failures in the Russian space program. The Soyuz is still consider by NASA officials to be the world’s most reliable space system.
