Cleaner NASA rover sees its shadow in Martian spring

Late afternoon lighting produced a dramatic shadow of NASA's Mars Exploration Rover Opportunity photographed by the rover's rear hazard-avoidance camera on March 20, 2014.

NASA's Hubble Space Telescope spots Mars-bound comet sprout multiple jets

How do you grow a supermassive black hole that is a million to a billion times the mass of our sun? Astronomers do not know the answer, but a new study using data from NASA's Wide-field Infrared Survey Explorer, or WISE, has turned up what might be the cosmic seeds from which a black hole will sprout. The results are helping scientists piece together the evolution of supermassive black holes -- powerful objects that dominate the hearts of all galaxies.

Mars Rover's next stop has sandstone variations

Variations in the stuff that cements grains together in sandstone have shaped the landscape surrounding NASA's Curiosity Mars rover and could be a study topic at the mission's next science waypoint.

NASA's Space Sunflower may help snap pictures of planets

A spacecraft that looks like a giant sunflower might one day be used to acquire images of Earth-like rocky planets around nearby stars. The prototype deployable structure, called a starshade, is being developed by NASA's Jet Propulsion Laboratory in Pasadena, Calif.

NASA spacecraft reveal new “Zebra Stripes” structure in Earth’s inner radiation belt

Scientists have discovered a new, persistent structure in Earth’s inner radiation belt using data from the twin NASA Van Allen Probes spacecraft. Most surprisingly, this structure is produced by the slow rotation of Earth, previously considered incapable of affecting the motion of radiation belt particles, which have velocities approaching the speed of light.

NASA Orbiter finds new gully channel on Mars

A comparison of images taken by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter in November 2010 and May 2013 reveal the formation of a new gully channel on a crater-wall slope in the southern highlands of Mars.

NASA releases first interactive mosaic of lunar North Pole

Scientists, using cameras aboard NASA's Lunar Reconnaissance Orbiter (LRO), have created the largest high resolution mosaic of our moon’s north polar region. The six-and-a-half feet (two-meters)-per-pixel images cover an area equal to more than one-quarter of the United States.

NASA centers team up to tackle sonic boom

Since the Concorde’s final landing at London’s Heathrow Airport nearly a decade ago, commercial supersonic air travel has been as elusive as a piece of lost luggage. However, this hasn’t stopped NASA from continuing the quest to develop solutions that will help get supersonic passenger travel off the ground once more.

Plasma plumes help shield Earth from damaging solar storms

The Earth's magnetic field, or magnetosphere, stretches from the planet's core out into space, where it meets the solar wind, a stream of charged particles emitted by the sun. For the most part, the magnetosphere acts as a shield to protect the Earth from this high-energy solar activity.

How did life arise? Fuel cells may have answers

How life arose from the toxic and inhospitable environment of our planet billions of years ago remains a deep mystery. Researchers have simulated the conditions of an early Earth in test tubes, even fashioning some of life's basic ingredients. But how those ingredients assembled into living cells, and how life was first able to generate energy, remain unknown.

NASA's Robonaut Legs headed for International Space Station (ISS)

NASA's built and is sending a set of high-tech legs up to the International Space Station for Robonaut 2 (R2), the station's robotic crewmember. The new legs will be delivered to the space station aboard the SpaceX-3 cargo resupply mission, due to launch March 16 from Cape Canaveral Air Force Station in Florida.

Report: Long-term warming likely to be significant despite recent slowdown

A new NASA study shows Earth's climate likely will continue to warm during this century on track with previous estimates, despite the recent slowdown in the rate of global warming.

NASA's THEMIS discovers new process that protects Earth from space weather

In the giant system that connects Earth to the sun, one key event happens over and over: solar material streams toward Earth and the giant magnetic bubble around Earth, the magnetosphere helps keep it at bay.

Great Video of NASA Astronauts Saluting Gravity Movie in Space

While Gravity didn’t win the Best Picture nod, it won more Academy Awards than any other movie on Oscar night. And appropriately enough, the film got another great nod that was very apropos, from space naturally. 

NASA tests new robotic refueling technologies

NASA has successfully concluded a remotely controlled test of new technologies that would empower future space robots to transfer hazardous oxidizer – a type of propellant – into the tanks of satellites in space today.

NASA's Hubble finds life is too fast, furious for runaway galaxy

The spiral galaxy ESO 137-001 looks like a dandelion caught in a breeze in this new Hubble Space Telescope image.

NASA takes on cancer with space station research

Invasive and systemic cancer treatment is a necessary evil for many people with the devastating diagnosis. These patients endure therapies with ravaging side effects, including nausea, immune suppression, hair loss and even organ failure, in hopes of eradicating cancerous tissues in the body.

NASA's Kepler finds 715 new worlds

Earlier this week, NASA's Kepler mission announced the discovery of 715 new planets. These newly-verified worlds orbit 305 stars, revealing multiple-planet systems much like our own solar system.

NASA eyes four spacecraft to study magnetic reconnection

First thing every morning, the engineering team for NASA's Magnetospheric Multiscale mission gathers for a 10-minute meeting. A white board sits at the front of the room with the day's assignments – who will wrap tape around the wires, which instruments need to be installed where, which observatory needs to undergo its next test.

NASA's smart SPHERES are about to get a whole lot smarter

Smart devices – such as tablets and phones – increasingly are an essential part of everyday life on Earth. The same can be said for life off-planet aboard the International Space Station. From astronaut tweets to Google+ Hangouts, our reliance on these mobile and social technologies means equipment and software upgrades are an everyday occurrence – like buying a new pair of shoes to replace a pair of well-worn ones.
