Scientists believe they have found a way to explain why there are not as many galaxies orbiting the Milky Way as expected.
Computer simulations of the formation of our galaxy suggest that there should be many more, smaller galaxies around the Milky Way than are observed through telescopes.
This has thrown doubt on the generally accepted theory of cold dark matter, a substance that scientists predict should allow for more galaxy formation around the Milky Way than is seen.
Tropical Storm Fengshen is a large storm and infrared imagery from NASA's Aqua satellite shows that it's about as long as the big island of Japan.
Tropical Depression 14W was a short-lived storm that only lasted through four bulletins from the Joint Typhoon Warning Center. NASA's Aqua satellite captured infrared data on the storm's cloud top temperatures as it passed over China's Hainan Island and headed toward a final landfall in mainland China.
NASA's Aqua satellite passed over Tropical Storm Norbert on September 7 before it weakened to a post- tropical storm. The AIRS instrument aboard captured infrared data that showed a "sliver" of strong thunderstorms remained around the center of the waning storm.
When the Atmospheric Infrared Sounder or AIRS instrument gathered infrared data on Tropical Storm Norbert on Sept. 7 at 4:53 p.m. EDT, it showed only a small area of strong thunderstorms around the center where cloud top temperatures were near the -63F/-52C threshold for strong storms.
CAMBRIDGE, Mass-- Around the world, there is more salty groundwater than fresh, drinkable groundwater. For example, 60 percent of India is underlain by salty water — and much of that area is not served by an electric grid that could run conventional reverse-osmosis desalination plants.
As Hurricane Norbert continued dropping heavy amounts of rainfall on Mexico's Baja California on September 5, NASA's TRMM satellite calculated the rain that had already fallen.
From its orbit in space, the Tropical Rainfall Measuring Mission or TRMM satellite has the capability of determining how much rainfall has occurred over given areas. Data from TRMM was compiled into a rainfall map that showed the rainfall generated from Tropical Storm Dolly and Hurricane Norbert from August 28 through September 4, 2014.
Over 60 million Americans are thought to experience mental illness in a given year, and the impacts of mental illness are undoubtedly felt by millions more in the form of family members, friends, and coworkers. Despite the availability of effective evidence-based treatment, about 40% of individuals with serious mental illness do not receive care and many who begin an intervention fail to complete it.
Tropical Storm Dolly fizzled out quickly on September 3 after making landfall in eastern Mexico, and NASA's Aqua satellite saw some of the remnants moving into southern Texas. NASA's TRMM satellite analyzed the rainfall occurring in the storm as it was approaching landfall.
The Eastern Pacific's Hurricane Norbert resembled a pinwheel in an image from NASA's Terra satellite as bands of thunderstorms spiraled into the center. NASA's Global Precipitation Measurement or GPM mission has helped forecasters see that Norbert has lost some of its organization early on September 4.
Boulder, Colo. — Sept. 4, 2014 — NASA's Alice ultraviolet (UV) spectrograph aboard the European Space Agency's Rosetta comet orbiter has delivered its first scientific discoveries. Rosetta, in orbit around comet 67P/Churyumov-Gerasimenko, is the first spacecraft to study a comet up close.
CORVALLIS, Ore. – Mothers who live in neighborhoods with plenty of grass, trees or other green vegetation are more likely to deliver at full term and their babies are born at higher weights, compared to mothers who live in urban areas that aren't as green, a new study shows.
The findings held up even when results were adjusted for factors such as neighborhood income, exposure to air pollution, noise, and neighborhood walkability, according to researchers at Oregon State University and the University of British Columbia.
(SACRAMENTO, Calif.) — Infant rhesus monkeys receiving different diets early in life develop distinct immune systems that persist months after weaning, a study by researchers from UC Davis, the California National Primate Research Center (CNPRC) at UC Davis and UC San Francisco have shown. The study, which compares breast- and bottle-fed infants, appears online September 3 in Science Translational Medicine.
New York | Heidelberg, 4 September 2014 -- Periodic chain-like nanostructures are widely used in nanoelectronics. Typically, chain elements include the likes of quantum rings, quantum dots, or quantum graphs. Such a structure enables electrons to move along the chain, in theory, indefinitely. The trouble is that some applications require localised electrons—these are no longer in a continuous energy spectrum but in a discrete energy spectrum, instead.
NASA has Tropical Storm Dolly covered by satellite and the remotely piloted Global Hawk aircraft. Both captured data on Dolly before it made landfall in eastern Mexico.
Approximately every 11 years, the sun undergoes a complete personality change from quiet and calm to violently active. The height of the sun's activity, known as solar maximum, is a time of numerous sunspots, punctuated with profound eruptions that send radiation and solar particles out into the far reaches of space.
