Chance meeting creates celestial diamond ring
Munich, Germany (SPX) Apr 13, 2014 -
Most stars with masses similar to that of our Sun will end their lives as white dwarfs - small, very dense, and hot bodies that slowly cool down over billions of years. On the way to this final phase of their lives the stars throw their atmospheres out into the space and create planetary nebulae, colourful glowing clouds of gas surrounding the small, bright stellar relics.

NASA Simulation Portrays Ozone Intrusions From Aloft
Greenbelt MD (SPX) Apr 13, 2014 -
Outdoor enthusiasts in Colorado's Front Range are occasionally rewarded with remarkable visibility brought about by dry, clear air and wind. But it's what people in the mountainous U.S. West can't see in conditions like this - ozone plunging down to the ground from high in the stratosphere, the second layer of the atmosphere - that has attracted the interest of NASA scientists, university scient ...

China uses satellite, drones to fight pollution
Beijing (XNA) Apr 13, 2014 -
China is using satellites and drones to detect air pollution around Beijing and the practice will be expanded, the Ministry of Environmental Protection said on Wednesday.
Satellites and drones, which can detect clandestine emissions and capture images with a resolution of up to 4 centimeters, have been used in the cities of Tangshan, Xingtai and Handan in north China's Hebei Province, a po ...

Hubble Extends Stellar Tape Measure 10 Times Farther Into Space
Baltimore MD (SPX) Apr 13, 2014 -
Using NASA's Hubble Space Telescope, astronomers now can precisely measure the distance of stars up to 10,000 light-years away - 10 times farther than previously possible.
Astronomers have developed yet another novel way to use the 24-year-old space telescope by employing a technique called spatial scanning, which dramatically improves Hubble's accuracy for making angular measurements. Th ...

Supernova Cleans Up Its Surroundings
Huntsville AL (SPX) Apr 13, 2014 -
Supernovas are the spectacular ends to the lives of many massive stars. These explosions, which occur on average twice a century in the Milky Way, can produce enormous amounts of energy and be as bright as an entire galaxy. These events are also important because the remains of the shattered star are hurled into space. As this debris field - called a supernova remnant - expands, it carries the m ...

Remote Troops Closer to Having High-Speed Wireless Networks Mounted on UAVs
Washington DC (SPX) Apr 08, 2014 -
Missions in remote, forward operating locations often suffer from a lack of connectivity to tactical operation centers and access to valuable intelligence, surveillance, and reconnaissance (ISR) data. The assets needed for long-range, high-bandwidth communications capabilities are often unavailable to lower echelons due to theater-wide mission priorities.
DARPA's Mobile Hotspots program ai ...
