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.
NASA scientists have successfully beamed an iconic image of the Mona Lisa to the Lunar Reconnaissance Orbiter (LRO) spacecraft from Earth.

NASA is conducting its first round of tests to develop robots capable of repairing and refueling satellites in space.
Astronomers using NASA's Spitzer and Hubble space telescopes have managed to probe the stormy atmosphere of a brown dwarf, creating the most detailed "weather map" yet for this class of cool, star-like orbs.
Astronomers believe they've found a large asteroid belt around Vega, the second brightest star in northern night skies.
NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) recently spotted the brilliant glow of two black holes lurking inside spiral galaxy IC342.
Another crucial instrument on the Curiosity Mars rover has had its first test: the Dust Removal Tool, used to sweep dust from the rover's target rocks.
NASA's Kepler mission has discovered four new planets that are less than twice the size of Earth and which orbit in their star's habitable zone.
NASA researchers are currently evaluating small tiles made of space trash to determine if they can be safely stored aboard spacecraft and used as radiation shielding during future deep-space missions.
Rolling robots like spiky tumbleweeds could be used to explore the moons of Mars, says a team of NASA, Stanford and MIT engineers.
NASA's released a new, stunning self-portrait of the Curiosity Mars rover, stitched together from dozens of high-resolution images.
