The magnetosphere, Earth's magnetic field, stretches from the core of the planet out into space. Here, the magnetosphere meets the solar wind, a stream of charged particles emitted by the sun. The magnetosphere, for the main part, acts to shield the Earth from this high-energy solar activity.

The first powerful "X-class" solar flare of 2014, in association with another solar phenomenon, a giant cloud of solar particles known as a coronal mass ejection (CME), erupted from the sun on Tuesday, sending radiation and particles speeding toward Earth and disrupting operations on the ground.

Data from NASA's Van Allen Probes mission has helped researchers resolve decades of scientific uncertainty over the origin of ultra-relativistic electrons in Earth's near space environment.

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

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.

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

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.

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

Researchers used data from the Van Allen Probes to reveal that the high-energy particles populating the 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.

Recalling The 2003 Nightmare Halloween Magnetic Storm

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 than what most kids get when they go Trick-or-Treating this All Hallow's Eve.

lightning strikes affect mountain tops

Using a simple magnetic compass and a little ingenuity, researchers have found that lighting strikes have a far greater impact on mountaintops than previously thought.

Space Weather Origins Revealed
2013-09-27 04:21:43

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.

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...
