By shooting the high-energy Omega laser onto precompressed samples of planetary fluids, scientists are gaining a better understanding of the evolution and internal structure of Jupiter, Saturn and extrasolar giant planets.The properties of dense helium (He) "” which happens to be a principal constituent of giant gas planets like Jupiter "” at thermodynamic conditions between those of condensed matter and high-temperature plasmas are theoretically challenging and unexplored...

The Internet is increasingly becoming a place for ultra-low-cost freelance writers to publish their online copy on Web sites such as Helium, Associated Content and ThisIsBy.US, site which make micropayments to writers willing to contribute material on a wide variety of subjects ranging from college basketball to how to best remove tattoos to where to find Dr. Seuss coloring pages. Angie Papple is one such writer. A chemicals specialist in the Army, in her spare time away from her duties she...

Researchers at the National Institute of Standards and Technology (NIST) and the University of Maryland have developed a new optical method that can detect individual neutrons and record them over a range of intensities at least a hundred times greater than existing detectors. The new detector, described at the March Meeting of the American Physical Society* by Charles Clark, a Fellow of the Joint Quantum Institute of NIST and the University of Maryland, promises to improve existing neutron...

By Jim McBride, Amarillo Globe-News, Texas Mar. 4--The Bureau of Land Management's crude helium enrichment unit north of Amarillo will be shut down for maintenance and component replacement through March 14. The temporary shutdown could potentially exacerbate a helium supply shortfall that began in 2006 because of spiraling worldwide demand. But BLM officials said they have coordinated the plant's shutdown with private refiners, who are prepared. "Doing this maintenance now is...

At last month's Cosmology Meets Condensed Matter conference in London, it emerged that space-time could be simulated in the lab using strange, unique substances known as "superfluids", which flow without resistance and can even climb up the walls of jars. The equations governing the particles inside the superfluids are similar to those that represent the early universe, said Ray Rivers at Imperial College London. "We hope that we can use these to check things in the lab that frankly we don't...

Astronomers may have found another way that stars evolve Astronomers have discovered white dwarf stars with pure carbon atmospheres. These stars possibly evolved in a sequence astronomers didn't know before. They may have evolved from stars that are not quite massive enough to explode as supernovae but are just on the borderline. All but the most massive two or three percent of stars eventually die as white dwarfs rather than explode as supernovae. When a star burns helium, it leaves "ashes"...

It's no mystery that over the years society has enjoyed amenities and technological advances made by NASA. Often these discoveries find their way into mainstream lifestyles through a process referred to as technology transfer or spinoffs. So can the agency that brought you semiconductor cubing, enriched baby food, improved athletic shoes and comfier mattresses help solve a mystery of national importance? The Charters of Freedom -- the Declaration of Independence, the Constitution of the...

Scientists hope to learn more about climate changes here on Earth by studying Venus. A prototype balloon could eventually study the planet's surface and examine its atmosphere and the bizarre winds and chemistry within it. A team of JPL, ILC Dover and NASA Wallops Flight Facility engineers designed, fabricated and tested the balloon. Slightly smaller than Earth, Venus is often regarded as Earth's sister planet. Both have similar densities, chemical compositions and gravities. However, its...

Helium may act as a "throttle" for the solar wind, setting its minimum speed, according to new results with NASA's Wind spacecraft. The solar wind is a diffuse stream of electrically conducting gas (plasma) constantly blowing from the sun. "This result gives us another clue about how the solar wind is accelerated, which may help us better understand space weather," said Dr. Justin Kasper of the Kavli Institute for Astrophysics and Space Research at the Massachusetts Institute of Technology,...

Solar Radiation -- Solar radiation is radiant energy emitted by the sun due to nuclear fusion reactions. Fusion is the process whereby stars produce huge quantities of energy from the fusion of hydrogen or helium, in one of the most efficient processes of energy generation. The radiation referred to is usually electromagnetic energy, particularly infrared radiation, visible light, and ultraviolet. Some stars are known to emit radiation of other wavelengths. Solar neutrinos are a...
