ASA's Goddard Space Flight Center has awarded the Raytheon Company a five year contract valued at up to $240 million to continue its support of the Earth Observing Systems Data and Information System (EOSDIS). This system ingests, archives and makes earth science data available to the scientific community worldwide. EOSIDS is NASA's portal for earth science data provided by both NASA and upcoming international satellite missions.
The Integral, Fermi and Swift space observatories have used the magnifying power of a cosmic lens to explore the inner regions of a supermassive black hole. Researchers used a star sitting between their target and Earth to ‘zoom in’ to the black hole and measure the size of the jet-emitting region — the first time this method has ever been used with gamma rays
Can an algorithm pass for an author? Can a robot rock the house? A series of contests is about to find out. Dartmouth is seeking AI algorithms that create human-quality short stories, sonnets and dance music that will be pitted against human-produced literature, poetry and music. Judges won't know which is which. The goal is to determine whether people can distinguish between the two and maybe even prefer computer-generated creativity.
On April 15, 2014, a Wilmington, DE, business owner, was driving home on the I-495 bypass, as he had done for 25 years. While traveling on the twin three-lane bridges that span the Christiana River, he noticed that the normally parallel bridges were offset by nearly 18 inches in height and the apparent listing of one of the lanes had created a large gap between the bridges through which the ground was visible, some four stories below.
Heading into the Independence Day weekend, materials that compute — what your clothes may say about you; Sandia’s Z machine solving an 80-year-old puzzle; an amazing satellite view of the San Francisco Bay area; a monster black hole waking after 26 years; a tactical toss camera that sends panoramic images back to a smartphone; and breaking key barriers that limit the distance information can travel in fiber optic cables, are all top hits.
NASA has joined a multi-agency field campaign studying summer storm systems in the U.S. Great Plains to find out why they often form after the sun goes down instead of during the heat of the day. Participants from eight research laboratories and 14 universities are collecting storm data to find out how and why they form. NASA’s DC-8 airborne laboratory began research flights June 30, 2015, from the Salina Regional Airport, Salina, KS.
A galaxy 23 million light-years away is the site of impressive, ongoing, fireworks. Rather than paper, powder and fire, this galactic light show involves a giant black hole, shock waves and vast reservoirs of gas. This galactic fireworks display is taking place in a spiral galaxy like the Milky Way. The galaxy is famous, however, for something our galaxy doesn't have — two extra spiral arms that glow in X-ray, optical and radio light.
The EU-funded What-if Machine (WHIM) project not only generates fictional storylines, but also judges their potential usefulness and appeal. It represents a major advance in the field of computational creativity. Science rarely looks at the whimsical, but that is changing as a result of the aptly named WHIM project. The ambitious project is building a software system able to invent and evaluate fictional ideas.
A new robot that raises its tail like a scorpion is scheduled to look at melted nuclear fuel inside one of the three wrecked Fukushima reactors in Japan. Toshiba, co-developer of the "scorpion" crawler, said the robot will venture into the Unit 2 reactor's primary containment vessel in August after a month of training for its handlers. Officials hope the robot can see the fuel in the pressure vessel in the middle of the reactor.
A 24-minute, high-resolution science documentary narrated Benedict Cumberbatch about the dynamics of the sun that features data-driven visualizations produced by NCSA at the University of Illinois at Urbana-Champaign debuted on June 30, 2015, at the Louisiana Art & Science Museum in Baton Rouge before rolling out to more than a dozen planetariums and science centers around the world.
A team of researchers led by UCLA electrical engineers has demonstrated a new way to harness light particles, or photons, that are connected to each other and act in unison no matter how far apart they are — a phenomenon known as quantum entanglement. In previous studies, photons have typically been entangled by one dimension of their quantum properties — usually the direction of their polarization.
NASA astronaut Scott Kelly (@StationCDRKelly) captured photographs and video of auroras from the International Space Station on June 22, 2015. Kelly wrote, "Yesterday's aurora was an impressive show from 250 miles up. Good morning from the International Space Station! #YearInSpace
This 600X image shows a live cultured human mesothelial cell activated to produce hyaluronan. It received an honorable mention in the 2014 Nikon Small World Photomicrophotography Competition, which recognizes excellence in photography with the optical microscope and was taken using confocal microscopy.
Planets tend to cool as they get older, but Saturn is hotter than astrophysicists say it should be without some additional energy source. The unexplained heat has caused a 2-billion-year discrepancy for computer models estimating Saturn’s age. Experiments at Sandia’s Z machine verified an 80-year-old untested proposition that molecular hydrogen, normally an insulator, becomes metallic if squeezed by enough pressure...
The intricate jumble depicted in this image from ESA’s Herschel space observatory shows the distribution of gas and dust in the Taurus Molecular Cloud, a giant stellar nursery about 450 light-years away in the constellation Taurus, the Bull. Dust is a minor but crucial ingredient in this diffuse mixture that provides the raw material for stars to form.
As we entered our first week of summer, the week’s biggest hits included a strong bent toward several “lighter” mathematical topics: learning how math drives Formula 1 and launches Angry Birds, inspiring young minds at MoMATH, and Pi Day under attack. You also won’t want to miss molecules exhibiting strange, exotic states, hot lava flows on Venus, and some of the coolest experimental technology showcased at this year’s Paris Air Show.
Unseen areas are troublesome for police and first responders: Rooms can harbor dangerous gunmen, while collapsed buildings can conceal survivors. In July, a startup will release its first line of tactical spheres, equipped with cameras and sensors that can be tossed into potentially hazardous areas to instantly transmit panoramic images of those areas back to a smartphone, giving officers and rescuers a safe glimpse into the unknown.
The image shows an entire live zebrafish embryo at 22 hours post-fertilization and single-cell resolution, enabling an insightful view of its early morphogenetic development. The embryo’s cell nuclei were fluorescently labeled and imaged with a SiMView custom light-sheet microscope. Color encodes depth in the image.
Over the past week, ESA's Integral satellite has been observing an exceptional outburst of high-energy light produced by a black hole that is devouring material from its stellar companion. X-rays and gamma rays point to some of the most extreme phenomena in the Universe, such as stellar explosions, powerful outbursts and black holes feasting on their surroundings.
Moving closer to the possibility of "materials that compute" and wearing your computer on your sleeve, researchers have designed a responsive hybrid material that is fueled by an oscillatory chemical reaction and can perform computations based on changes in the environment or movement, and potentially even respond to human vital signs. The material system is sufficiently small and flexible to ultimately be integrated into a fabric.
At the recent International Conference on Robotics and Automation, researchers presented a printable origami robot that folds itself up from a flat sheet of plastic when heated and measures about 1 cm from front to back. Weighing only a third of a gram, the robot can swim, climb an incline, traverse rough terrain, and carry a load twice its weight. Other than the self-folding plastic sheet, the only component is a permanent magnet.
Jill Hruby was named the next president and director of Sandia National Laboratories, the country’s largest national lab. When she steps into her new role July 17, she will be the first woman to lead a national security laboratory. A Sandia staff member and manager for the past 32 years, Hruby most recently oversaw Sandia efforts in nuclear, biological and chemical security, homeland security, counterterrorism and energy security.
