A research project 10 years in the making is now orbiting the Earth, much to the delight of its creator Rohit Trivedi, a senior metallurgist at the U.S. Department of Energy's Ames Laboratory.
A new study led by the University of Colorado at Boulder indicates most of the world's low-lying river deltas are sinking from human activity, making them increasingly vulnerable to flooding from rivers and ocean storms and putting tens of millions of people at risk.
Typhoon Choi-Wan passed the island of Iwo To stirring up heavy surf, hurricane-force winds and torrential, flooding rains. This weekend, it will continue on its northeasterly track paralleling Japan, while its center remains in the open Western Pacific Ocean.
Marty was still holding onto tropical storm status on September 18, with maximum sustained winds near 40 mph and taking a slow march through the Eastern Pacific Ocean.
The Planck space telescope has returned its first images of the sky. The mission, run by the European Space Agency with participation from NASA, will map tiny differences in microwave radiation left over from the Big Bang, allowing scientists to get a better picture of the structure of the universe when it was about 400,000 years old.
NASA's Lunar Reconnaissance Orbiter (LRO), an unmanned mission to comprehensively map the entire moon, has returned its first data. One of the seven instruments aboard, the Diviner Lunar Radiometer Experiment, is making the first global survey of the temperature of the lunar surface while the spacecraft orbits some 31 miles above the moon.
NASA's Aqua satellite again flew over Super Typhoon Choi-Wan late last night and captured visible and infrared imagery of the monster typhoon. Aqua's Atmospheric Infrared Sounder (AIRS) instrument and Moderate Imaging Spectroradiometer (MODIS) captured two different views of Choi-Wan's clouds.
NASA and the Japanese Space Agency's Tropical Rainfall Measuring Mission (TRMM) satellite flew over the center of Super Typhoon Choi-Wan at 2:34 EDT on September 17, 2009 and captured heavy rainfall around the storm's center.
Marty is struggling to hold onto tropical storm status, and things are just going to get worse for him, as he moves into an area with stronger wind shear. Infrared satellite imagery from NASA's Aqua satellite showed that Marty's thunderstorm cloud tops are not as cold as they were earlier today, September 17, and his cloud pattern has become a little less organized.
NASA's Lunar Reconnaissance Orbiter (LRO), launched on June 18 of this year, has begun its extensive exploration of the lunar environment and will return more data about the Moon than any previous mission. The Lyman-Alpha Mapping Project (LAMP), developed by Southwest Research Institute, is an integral part of the LRO science investigation.
Results: MIT researchers and colleagues have solved a longstanding mystery about a pair of stars called DI Herculis whose peculiar rotation (a shift in their orbit that was four times slower than expected) had remained a mystery for three decades. The real enation is simple: The stars are rotating tipped over on their sides, relative to their orbits around each other.
GREENBELT, Md. -- In a break from its usual task of searching for distant cosmic explosions, NASA's Swift satellite has acquired the highest-resolution view of a neighboring spiral galaxy ever attained in the ultraviolet. The galaxy, known as M31 in the constellation Andromeda, is the largest and closest spiral galaxy to our own.
GREENBELT, Md. - NASA's James Webb Space Telescope is starting to come together. A major component of the telescope, the Integrated Science Instrument Module structure, recently arrived at NASA Goddard Space Flight Center in Greenbelt, Md. for testing in the Spacecraft Systems Development and Integration Facility.
HOUSTON -- (Sept. 15, 2009) -- A research project looking for ways to reduce bone loss in astronauts may yield methods of improving the bone health of cancer patients undergoing radiation treatment.
Microwave imagery from NASA's Aqua satellite revealed extremely high thunderstorms in Typhoon Choi-Wan as it began passing the island of Sai-Pan in the Western Pacific Ocean. The U.S. National Weather Service has already issued a tropical storm warning and a typhoon watch for Tinian, Saipan and Agrihan in the Northern Mariana Islands.
