Concordia Is Opening The Curtains

Set against a star-studded backdrop and a splash of the Milky Way, the green glow of an auroral curtain pervades the permanently dark winter skies of the South Pole.

Earth’s Magnetosphere Operates Like A Filter
2012-10-24 11:46:18

ESA’s quartet of satellites studying Earth’s magnetosphere, Cluster, has discovered that our protective magnetic bubble lets the solar wind in under a wider range of conditions than previously believed.

Coronal Mass Ejection Captured By SOHO
2012-09-29 08:20:34

At 10:23 pm EDT on September 27, 2012, NASA's Solar and Heliospheric Observatory captured an image of a particularly wide coronal mass ejection that erupted from the Sun.

Magnetic Turbulence Could Cause Solar Wind Temperature Rise
2012-08-19 06:44:46

Magnetic turbulence is most likely the reason that solar wind moving away from our sun and our solar system is hotter than it theoretically should be, according to new research from scientists at the University of Warwick.

Tracking The Sun's Electron Beams

Understanding weather patterns here on Earth is a complicated process, with scientists teasing apart different kinds of atmospheric movements, such as the great jet streams that can move across a whole hemisphere versus more localized, intricate flows, to create a whole picture.

Cluster Examines Thin Current Sheets In The Magnetosphere
2012-08-02 05:08:15

The Universe is filled with plasma, a charged gas consisting of ions and electrons. Thin sheets, or boundaries, with currents separate large plasma regions. These boundaries are where most of the exciting action in space happens.

Waves In The Magnetosphere's Thin Boundaries Looked At By Cluster
2012-08-01 16:08:16

Exploiting a favorable configuration of ESA's Cluster mission spacecraft, scientists have detected and characterized lower hybrid drift waves, a special kind of plasma waves that develop in thin boundaries both in space and in the laboratory.

Solar Winds Affect Earth's Magnetosphere
2012-08-01 13:04:29

Weather has always affected our lives, but we are increasingly reliant on technology that can be disrupted by space weather. Geomagnetic storms, which are major disturbances of the magnetosphere, cause high altitude flights to be rerouted, costing many thousands of dollars per flight; cause GPS errors of up to 151 feet; and affect the International Space Station and satellites.

Geotail Mission Celebrates 20th Anniversary

Twenty years ago, the United States relationship with Japan showed just how restored it was since the second world war, as the two countries' space agencies launched a joint mission together.

Solar Physics
2012-05-02 19:16:53

Solar Physics is a journal for solar and solar-stellar research and the study of solar terrestrial physics. Founded in 1967 by solar physicist Cornelis de Jager and publisher D. Reidel, the journal treats all aspects of solar physics, ranging from the internal structure of the Sun and its evolution, to outer corona and solar wind in interplanetary space. Solar Physics has four more than forty years been the principal journal for publications of fundamental research on the Sun. It is...

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...

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...

Corona -- The corona is the luminous "atmosphere" of the Sun extending millions of kilometers into space, most easily seen during a total solar eclipse. An interesting feature of the corona is the fact that it is much hotter than the visible "surface" of the Sun; the photosphere is approximately 6000°C compared to the corona at over one million °C. The corona is much less dense than the photosphere, however, and so produces less light. The exact mechanism by which the corona is...

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...
