NASA Rover Opportunity Captured Images of Comet Siding Spring

October 23, 2014 3:56 pm | by NASA Jet Propulsion Laboratory | News | Comments

NASA's Mars Exploration Rover Opportunity captured images of a comet passing much closer to Mars than any previous known comet flyby of Earth or Mars. The images of comet Siding Spring were taken against a backdrop of the pre-dawn Martian sky on October 19, 2014. Images of comet A1 Siding Spring from the rover's panoramic camera (Pancam) are online.

Sunset Rainbow over Samos Island, Greece

June 26, 2014 9:15 am | News | Comments

This gorgeous, high-arching double rainbow signaled the end to a stormy spring day. It was taken at sunset from Samos Island, Greece, a small island in the Aegean Sea. Reddened colors of the primary and secondary bows result from the increased path length of sunlight when the Sun is below the horizon.

Giant Landform on Mars

June 9, 2014 12:50 pm | by Matthew Chojnacki, NASA | News | Comments

Sandy landforms formed by the wind, or aeolian bedforms, are classified by the wavelength — or length — between crests. On Mars, we can observe four classes of bedforms (in order of increasing wavelengths): ripples, transverse aeolian ridges (known as TARs), dunes, and what are called “draa.” All of these are visible in this Juventae Chasma image.

Wonders in the Antarctic Sky

May 15, 2014 2:12 pm | by Adam Voiland, NASA | News | Comments

In 43 hours across five science flights in late November 2013, NASA's P-3 research aircraft collected more than 20,000 kilometers (12,000 miles) worth of science data. Instruments gathered information about the thickness of the ice over subglacial lakes, mountains, coasts and frozen seas. The flights over Antarctica were part of Operation IceBridge, a multi-year mission to monitor conditions in Antarctica and the Arctic

Drones Unearth More Details about Chaco Culture

April 22, 2014 3:40 pm | by Susan Montoya Bryan, Associated Press | News | Comments

Recently published research describes how archaeologists outfitted a customized drone with a heat-sensing camera to unearth what they believe are ceremonial pits and other features at the site of an ancient village in New Mexico. The discovery of the structures hidden beneath layers of sediment and sagebrush is being hailed as an important step that could help archaeologists shed light on mysteries long buried by eroding desert landscapes

Geologic Icon: The Grand Canyon

April 21, 2014 9:04 am | by M. Justin Wilkinson, Jacobs at NASA-JSC | News | Comments

The Grand Canyon in northern Arizona is a favorite for astronauts shooting photos from the International Space Station, as well as one of the best-known tourist attractions in the world. The steep walls of the Colorado River canyon and its many side canyons make an intricate landscape that contrasts with the dark green, forested plateau to the north and south.

Martian Sand Dunes in Spring

March 12, 2014 10:34 am | by Candy Hansen, NASA | News | Comments

Mars’ northern-most sand dunes are beginning to emerge from their winter cover of seasonal carbon dioxide (dry) ice. Dark, bare south-facing slopes are soaking up the warmth of the sun. The steep lee sides of the dunes are also ice-free along the crest, allowing sand to slide down the dune.

False-Color Image Highlights Earth’s Plant Growth

March 10, 2014 9:55 am | by Holli Riebeek, NASA | News | Comments

On August 3, 2004, NASA’s Mercury Surface, Space Environment, Geochemistry, and Ranging (MESSENGER) spacecraft began a seven-year journey, spiraling through the inner solar system to Mercury. One year after launch, the spacecraft zipped around Earth, getting an orbit correction from Earth’s gravity and getting a chance to test its instruments by observing its home planet.

An active region of the sun just rotating into the view of NASA's Solar Dynamics Observatory gives a profile view of coronal loops over about a two-day period, from February 8 to 10, 2014. Coronal loops are found around sunspots and in active regions.

Rise of the Compliant Machines: Sociable Humanoids could Help Advance Human-robot Interaction

February 24, 2014 3:58 pm | by Rob Matheson, MIT News Office | News | Comments

Are we on the brink of a robotics revolution? That’s what numerous media outlets asked last December when Google acquired eight robotics companies that specialize in such innovations as manipulation, vision, and humanoid robots. Among those acquisitions was MIT spinout Meka Robotics. Founded in 2006, Meka was an early creator of “compliant” humanoid robots that now work safely alongside humans in everyday environments

Martian Dunes Flying in Formation

February 20, 2014 4:50 pm | by Alfred McEwen, NASA | News | Comments

Migratory birds and military aircraft often fly in a V-shaped formation. The “V” formation greatly boosts the efficiency and range of flying birds, because all except the first fly in the upward motion of air — called upwash — from the wingtip vortices of the bird ahead. In this image of a dune field on Mars ...

Full View of Asteroid Vesta

February 12, 2014 1:01 pm | by NASA | News | Comments

As NASA's Dawn spacecraft travels to its next destination, this mosaic synthesizes some of the best views the spacecraft had of the giant asteroid Vesta. Dawn studied Vesta from July 2011 to September 2012. The towering mountain at the south pole — more than twice the height of Mount Everest — is visible at the bottom of the image. The set of three craters known as the "snowman" can be seen at the top left.

In an age when we're able to consume content so many different ways — and that's a good thing, mostly — let's declare right now that there's only one truly correct way to experience "Gravity," Alfonso Cuaron's thrilling new space film. In a theater. On a huge screen. And in 3-D. Yes, even for all you 3-D naysayers — we hear you, but this is the movie you HAVE to see in 3-D.

Seamless Photography: Using Mathematical Models for Image Stitching

October 2, 2013 2:21 pm | by Society for Industrial and Applied Mathematics | News | Comments

A photo captures only as much as the camera in use will allow, and is therefore limited by the field of view of the camera's lens. In the case of smartphones and many advanced cameras, the view from the lens is much smaller than the view from your own eyes.

High-Speed Camera Captures Dancing Droplets for Scientific Photo Album

August 8, 2013 2:16 pm | by Cornell University | News | Comments

The splash from rain hitting a windowpane or printer ink hitting paper all comes down to tiny droplets hitting a surface, and what each of those droplets does. Cornell University researchers have produced a high-resolution “photo album” of more than 30 shapes an oscillated drop of water can take. The results, a fundamental insight into how droplets behave, could have applications in everything from inkjet printing to microfluidics.

Bombardment: Mars Camera Reveals Hundreds of Impacts Each Year

May 15, 2013 7:09 pm | by University of Arizona | News | Comments

Scientists using images from NASA's Mars Reconnaissance Orbiter, or MRO, have estimated that the planet is bombarded by more than 200 small asteroids or bits of comets per year forming craters at least 12.8 feet (3.9 meters) across. Researchers have identified 248 new impact sites on parts of the Martian surface in the past decade

New Camera System Creates High-resolution 3-D Images from Up to a Kilometer Away

April 4, 2013 12:07 pm | News | Comments

A standard camera takes flat, 2-D pictures. To get 3-D information, such as the distance to a far-away object, scientists can bounce a laser beam off the object and measure how long it takes the light to travel back to a detector. The technique, called time-of-flight (ToF), is already used in machine vision, navigation systems for autonomous vehicles, and other applications, but many current ToF...
