NASA has created a 3D reconstruction of ancient water channels below the surface of Mars, revealing evidence of a catastrophic flood in the last 500 million years.
The Curiosity ground team has been forced to switch the Mars rover to a redundant onboard computer, thanks to a memory problem.
The first NASA spacecraft designed to fly astronauts beyond Earth orbit since the Apollo era of yore is apparently well on its way to making a flight test next year.
It may look like something from "The Lord of the Rings," trilogy (think the Eye of Sauron), but this fiery swirl is actually a real-life planetary nebula known as ESO 456-67 imaged by NASA's Hubble space telescope.
The Earth temporarily gained a third radiation belt last year, NASA's Van Allen Probes mission has revealed.
NASA's Hubble space telescope has captured an image of HH 151, a bright jet of glowing material trailed by an intricate, orange-hued plume of gas and dust.
Most people would probably expect to find millions of dollars worth of cutting-edge equipment at a NASA research facility. And they would be right, of course, but there may also be some surprises waiting for the unsuspecting visitor.
NASA's Kepler mission has found the smallest planet yet around a star similar to our sun.
NASA engineers managed to restore real-time communications with the International Space Station (ISS) after connections were apparently severed following a routine software update.
The scientific community is aflutter after reports, images, and video of a massive meteor explosion in Russia clogged the Internet early Friday morning.
New data from NASA's Chandra X-ray Observatory indicates that a highly distorted supernova remnant may contain the most recent black hole formed in our Milky Way galaxy.
The Middle East has lost fresh water reserves equivalent to the entire Dead Sea over the last ten years, data from NASA satellites shows.
NASA's Landsat Data Continuity Mission (LDCM) made a textbook launch at 1:02 pm EST yesterday from Vandenberg Air Force Base in California.
NASA's Curiosity rover has, for the first time, used the drill on its robotic arm to bore into a rock on Mars and extract a sample for analysis.
The further away scientists look, the further back in time they see. Astronomers use this method to study the evolution of the Universe by analyzing nearby and more distant galaxies and comparing their features.
NASA's ability to track satellites and orbiting spacecraft is about to get a big boost, following the launch last night of a next-generation communication satellite.
This past week, NASA resurrected the stalwart F-1 engine that powered the Saturn V rocket, test firing its gas generator at the Marshall Space Flight Center in Huntsville, Ala.
NASA has signed up to join the European Space Agency's (ESA's) Euclid mission, a space telescope due to launch in 2020 and designed to investigate dark matter and dark energy.
In some dramatic images, astronomers have for the first time observed magnetic braids of super-hot matter on the surface of the sun, the first clear evidence of energy transfer from its magnetic field to the solar atmosphere or corona.
NASA's Mars Reconnaissance Orbiter (MRO) has found evidence that McLaughlin Crater once contained a lake fed by flowing groundwater.
