Latest Magnetosphere Stories
GREENBELT, Md., Oct. 27 /PRNewswire-USNewswire/ -- The magnetometers developed at NASA's Goddard Space Flight Center in Greenbelt, Md., for the Juno mission to Jupiter were delivered recently to Lockheed Martin in Denver, Colo.
Flight Dynamics data from THEMIS-B (one of the two ARTEMIS spacecraft) indicated that one of the EFI (electric field instrument)spherical tip masses may have been struck by a meteoroid at 0605 UT on October 14.
From Earth, the Sun looks like a calm, placid body that does little more than shine brightly while marching across the sky.
The aurora borealis, or Northern Lights, have dwindled in the last five years, becoming more rare than at any other time in the last hundred years, said the Finnish Meteorological Institute on Tuesday.
The Cassini spacecraft has made the first observations from within the radio aurora of another planet than Earth.
A new movie and images showing Saturn's shimmering aurora over a two-day period are helping scientists understand what drives some of the solar system's most impressive light shows.
Today (September 1), space scientists around the world are celebrating ten years of ground-breaking discoveries by 'Cluster', a mission that is illuminating the mysteries of the magnetosphere, the northern lights and the solar wind.
LAUREL, Md., Aug. 18 /PRNewswire-FirstCall/ -- The Johns Hopkins University Applied Physics Laboratory (APL), with help from The Boeing Company (NYSE: BA) and Iridium Communications Inc. (Nasdaq: IRDM), has successfully implemented a new space-based system to monitor Earth's space environment.

Planetary and Space Science is a peer-reviewed scientific journal established in 1959 and published by Elsevier 15 times per year. As of May 2012, the editor-in-chief is Rita Schulz (The Netherlands). The journal publishes original research articles and short communications. The main focus is on solar system processes which encompass multiple areas of the natural sciences. Research that involves planetary and space sciences involves many disciplines. Celestial mechanics is part of these...
Hannes Olof GÃ¶sta AlfvÃ©n (May 30, 1908 - April 2, 1995) was a Swedish plasma physicist born in NorrkÃ¶ping, Sweden. AlfvÃ©n received his PhD from the University of Uppsala in 1934. His thesis was titled "Investigations of the Ultra-short Electromagnetic Waves." He was originally trained as an electrical power engineer and later moved on to research and teaching in the fields of plasma physics. AlfvÃ©n made many contributions to plasma physics, including theories describing the...
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...
Heliopause -- The heliopause is the boundary where our Sun's solar wind is stopped by the interstellar medium. The solar wind blows a "bubble" in the interstellar medium (the rareified hydrogen and helium gas that permeates the galaxy). The point where the solar wind's strength is no longer great enough to push back the interstellar medium is known as the heliopause, and is often considered to be the outer "border" of the solar system. The distance to the heliopause is not precisely...
Aurora -- The Polar Aurora are natural displays of light in the sky that can be seen with the unaided eye only at night. An auroral display in the Northern Hemisphere is called the aurora borealis, or the northern lights; in the Southern Hemisphere it is called the aurora australis. Auroras are the most visible effect of the sun's activity on the earth's atmosphere. The beautiful and often eerie curtains of light in the night time sky have been observed by people for millennia. An aurora...
