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.
A camera aboard one of NASA's twin Gravity Recovery And Interior Laboratory (GRAIL) lunar spacecraft has returned its first unique view of the far side of the moon. Thousands of fourth- to eighth-grade students will select target areas on the lunar surface and send requests to the GRAIL MoonKAM Mission Operations Center in San Diego. Photos of the target areas will be sent back by the satellites for students to study.
Teams from three of the top United States aerospace corporations have spent the last year studying how to meet NASA’s sustainability goals for cleaner, more efficient aircraft. Among the requirements that prompted adventurous design work from the companies was a 50% reduction in fuel consumption and a 75% reduction in harmful emissions.
Most astrophysicists stare at the night sky and look at stars. But Lance Simms from Lawrence Livermore National Laboratory looks at the blackness of night and knows there something else there. Simms has been working for a year on a NASA project called the Cosmic X-Ray Background Nanosatellite. The breadbox-sized satellite, set for an August launch, will gather X-ray data from the cosmos and beam it back to Earth.
Proof that water flowed through underground fractures on Mars at some point in its history has been discovered by NASA’s Opportunity rover. Bright veins of a mineral, most likely gypsum, were observed by the rover and geologists judge by the formation that it was deposited by water.
The Kepler planet-hunting telescope may have found a second Earth. Scientists say the temperature on the surface of the planet is about a comfortable 22.2 C (72 F). Its star could almost be a twin of our sun, and it likely has water and land.
NASA's Dryden Flight Research Center recently completed NASA’s latest quiet sonic boom research study at Edwards Air Force Base. The Waveforms and Sonic boom Perception and Response, or WSPR, project gathered data from a select group of more than 100 volunteer Edwards Air Force Base residents on their individual attitudes toward sonic booms produced by aircraft in supersonic flight over Edwards.
A strangely powerful, long-lasting gamma-ray burst on Christmas Day, 2010 has finally been analyzed to the satisfaction of a multinational research team. Called the Christmas Burst, GRB 101225A was freakishly lengthy and it produced radiation at unusually varying wavelengths.
Brown University physicists have set the strongest limit for the mass of dark matter, the mysterious particles believed to make up nearly a quarter of the universe. The researchers report that dark matter must have a mass greater than 40 GeV. The distinction is important because it casts doubt on recent results from underground experiments that have reported detecting dark matter.
Indiana University astronomer Samir Salim believes the vast archives produced by NASA's space telescopes and ground-based observatories hold the right information to create the largest resource ever for the study of how star formation proceeds in galaxies.
In order to separate human-caused global warming from the "noise" of purely natural climate fluctuations, temperature records must be at least 17 years long, according to climate scientists. To address criticism of the reliability of thermometer records of surface warming, Lawrence Livermore National Laboratory scientists analyzed satellite measurements of the temperature of the lower troposphere and saw a clear signal of human-induced warming of the planet.
Dwarf galaxies are the most common type in the universe, but the 9 billion-year-old examples found by NASA’s Hubble telescope are unusually prolific and numerous. The rapid star-birth seen in these newly found examples may force astronomers to reassess their understanding of the ways in which galaxies form.
A Naval Research Laboratory instrument designed to study the Earth's thermosphere is part of a future science mission that has been selected by NASA for evaluation for flight.
The space shuttle program may have ended, but data the space craft collected over the past three decades are still helping advance science. Researchers at the University of California, San Diego recently used measurements from NASA's Shuttle Radar Topography Mission to predict how changes in elevation, such as hills and valleys, and the shadows they create, impact power output in California's solar grid.
A new NASA study suggests if life ever existed on Mars, the longest lasting habitats were most likely below the Red Planet's surface. Spectral evidence gathered by orbiters support a new hypothesis that persistent warm water was confined to the subsurface, and erosional were carved during brief periods when the surface supported stable water.
After a years-long delay, NASA’s newest climate satellite blasted into space early Friday on a dual mission to improve weather forecasts and monitor climate change. Five scientific instruments will extend more than 30 key long-term NASA datasets, including ozone layer measurements, land cover, and ice cover.
When the M-Cubed satellite, built by University of Michigan students, goes into orbit, it will become the first CubeSat to test a NASA instrument for major space missions. It is scheduled to be launched on October 28.
A mystery that began nearly 2,000 years ago, when Chinese astronomers witnessed what would turn out to be an exploding star in the sky, has been solved. New infrared observations from two NASA space telescopes reveal how the first supernova ever recorded occurred.
