Oil Drilling Costs, Impacts Improved Using Modern Compass Technology
2013-12-20 08:05:12

Gerard LeBlond for redorbit.com - Your Universe Online Oil and gas drilling companies are using the Earth’s magnetic field along with modern technology to reduce the cost and decrease the environmental impact while increasing production. The technology being used was discussed in the 2013 fall issue of Oilfield Review. It also emphasizes on the public-private partnership between the US Geological Survey (USGS) and partners to employ this technology and its uses around the world....

Decades-old Mystery In Earth's Upper Atmosphere Solved
2013-12-18 14:51:49

University of California - Los Angeles New research published in the journal Nature resolves decades of scientific controversy over the origin of the extremely energetic particles known as ultra-relativistic electrons in the Earth's near-space environment and is likely to influence our understanding of planetary magnetospheres throughout the universe. Discovering the processes that control the formation and ultimate loss of these electrons in the Van Allen radiation belts — the rings...

Earth's Van Allen Belts Thrust Particles To Near The Speed Of Light
2013-12-04 14:38:49

Lee Rannals for redOrbit.com - Your Universe Online NASA’s twin Van Allen Probes have led to another new discovery of Earth’s mysterious radiation belts. Researchers used data from the NASA spacecraft to reveal that the high-energy particles populating the Van Allen radiation belts can be accelerated to nearly the speed of light. This finding comes on the heels of a related discovery showing similar particle acceleration but on a microscopic, rather than planetary, scale. “The...

[ Watch the Video: Is There Space Weather In Store For Trick-Or-Treaters? ] Lawrence LeBlond for redOrbit.com - Your Universe Online As Halloween approaches, most people are thinking about costume parties, tricks and treats, haunted hayrides and perhaps a rogue werewolf running amok. But for scientists, this October 31 may provide a scare much different from what most kids get when they go Trick-or-Treating this All Hallow's Eve. The NOAA/NWS Space Weather Prediction Center on...

lightning strikes affect mountain tops
2013-10-15 10:20:36

[ Watch the Video: Lightning Strikes Can Change Mountains ] Brett Smith for redOrbit.com - Your Universe Online Using a simple magnetic compass and a little ingenuity, researchers from the University of the Witwatersrand in Johannesburg, South Africa have found that lighting strikes have a far greater impact on mountaintops than previously thought, according to a report of their experiments in the journal Geomorphology. During powerful thunderstorms, lightning strikes can hit rocks...

Space Weather Origins Revealed

[ Watch the Video: What Really Causes Space Weather? ] redOrbit Staff & Wire Reports - Your Universe Online Research published in Friday’s issue of the journal Science looks to shed new light on how changing environmental conditions in near-Earth space known as “space weather” can occur. Space weather is caused by solar storms – powerful eruptions of solar material and magnetic fields into interplanetary space – and can interfere with wireless communication and GPS...

Origins Of Unusual Radiation Ring

John P. Millis, PhD for redOrbit.com - Your Universe Online [ Watch the Video: Ultra-fast Electrons Explain Third Radiation Belt ] At the dawn of the space race, as two global powers jockeyed for technological supremacy, the ultimate goal was to be the first to send astronauts into space and onto the Moon. While space exploration is rife with challenges, one hurdle in particular brought into question whether man would ever leave low Earth orbit: the Van Allen radiation belts. These...

Researchers May Have Solved The Spin Mystery Of Earth's Core
2013-09-17 06:18:52

April Flowers for redOrbit.com - Your Universe Online For the last 300 years at least, we have been questioning what direction the center of the earth spins. A group of scientists from the University of Leeds, UK, and the Swiss Federal Institute of Technology may have found the answer. According to the study, published in Proceedings of the National Academy of Sciences (PNAS), the Earth's inner core - made of solid iron - "superrotates" in eastward directions. This means it spins faster...

[ Watch the Video: Earth’s Plasmasphere and the Van Allen Belts ] April Flowers for redOrbit.com - Your Universe Online For more than half a century, the invisible bubble created by Earth's magnetic field - the magnetosphere - has been studied by space missions. The discovery of Earth's radiation belts in 1958 was one of the first scientific breakthroughs made by a spacecraft. The Explorer 1 satellite revealed two concentric, tire-shaped belts of highly energetic (0.1–10 MeV)...

Several Key Discoveries During Van Allen Probes’ First Year
2013-09-01 07:49:38

redOrbit Staff & Wire Reports – Your Universe Online NASA’s twin Van Allen Probes entered their second year of service Friday having already provided a wealth of new information about the layers of energetic charged particles located above our planet. According to the US space agency, data collected by the probes since their August 30, 2012 launch has already led to “several significant discoveries” about the Van Allen radiation belts -- some of which came within the first...

The compass is a tool that helps the user navigate using the Earth's magnetic poles by using a magnetized pointer that reacts to magnetic fields. Since a compass can be used to calculate a heading it quickly improved the safety and efficiency of travel, especially ocean travel. It has only recently been replaced by Global Positioning Systems. It works by indicating the direction of the magnetic north of a planet's magnetosphere. Generally the face of a compass highlights the north, south,...

Ring Current
2004-10-19 04:45:44

Ring Current -- A ring current is an electric current carried by charged particles trapped in a planet's magnetosphere. It is caused by the longitudinal drift of energetic (10-200 keV) particles. Earth's Ring Current Earth's ring current is responsible for geomagnetic storms. The ring current system consists of a band, at a distance of 3-5 RE(1), which lies in the equatorial plane and circulates clockwise around the Earth (when viewed from the north). The particles of this region...

Van Allen Radiation Belt -- The Van Allen radiation belt is a torus of energetic charged particles around Earth, trapped by Earth's magnetic field. The presence of a radiation belt had been theorized prior to the Space Age and the belt's presence was confirmed by the Explorer I on January 31, 1958 and Explorer III missions, under Doctor James Van Allen. The trapped radiation was first mapped out by Explorer IV and Pioneer III. Qualitatively, it is useful to view this belt as consisting...
