WASHINGTON, Sept. 30 /PRNewswire-USNewswire/ -- New data from NASA's Interstellar Boundary Explorer, or IBEX, spacecraft, reveal that conditions at the edge of our solar system may be much more dynamic than previously thought. Future exploration missions will benefit in design and mission objectives from a better understanding of the changing conditions in this outer region of our solar system.

When NASA launched the Interstellar Boundary Explorer (IBEX) on October 19, 2008, space physicists held their collective breath for never-before-seen views of a collision zone far beyond the planets, roughly 10 billion miles away. That's where the solar wind, an outward rush of charged particles and magnetic fields continuously spewed by the Sun, runs into the flow of particles and fields that permeates interstellar space in our neighborhood of the Milky Way galaxy. No spacecraft had ever...

NASA has chosen the Naval Research Laboratory's Wide-field Imager to be part of the Solar Probe Plus mission slated for launch no later than 2018. The Solar Probe Plus, a small car-sized spacecraft will plunge directly into the sun's atmosphere approximately four million miles from our star's surface. It will explore a region no other spacecraft ever has encountered in an effort to unlock the sun's biggest mysteries. For decades, scientists have known that the corona, or the outer...

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 Northern Lights typically follow an eleven-year "solar cycle," in which frequency of the phenomena increases to a maximum point then begins to taper off toward a minimum and then repeats the cycle. The last solar minimum occurred in 2008, but seems to have continued "on and on and on,"...

The Cassini spacecraft has made the first observations from within the radio aurora of another planet than Earth. The measurements, which were taken when the spacecraft flew through an active auroral region in 2008, show some similarities and some contrasts between the radio auroral emissions generated at Saturn and those at Earth.  Results were presented last week by Dr Laurent Lamy at the European Planetary Science Congress in Rome, and recently published in Geophysical Research...

Solar storms don't always travel in a straight line. But once they start heading in our direction, they can accelerate rapidly, gathering steam for a harder hit on Earth's magnetic field. So say researchers who have been using data from NASA's twin STEREO spacecraft to unravel the 3D structure of solar storms. Their findings were presented in the Sept. 21 issue of Nature Communications. "This really surprised us," says co-author Peter Gallagher of Trinity College in Dublin, Ireland. "Solar...

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. Cluster is a European Space Agency mission, launched in summer 2000. It consists of a unique constellation of four spacecraft flying in formation around the Earth, studying the interaction between the solar wind and the magnetosphere. The spacecraft each carry an...

Invitation to a media briefing on September 1, 2010 Media representatives are cordially invited to a briefing on the occasion of ten years of scientific discoveries by ESA's Cluster mission. Over the past decade, Cluster's four satellites have provided extraordinary insights into the largely invisible interaction between the Sun and Earth. The media briefing takes place at ESA's European Space Operations Centre (ESOC) in Darmstadt, Germany, on September 1, 2010 from 11:00 "“ 12:00...

Imagine floating 35,000 miles above the sunny side of Earth. Our home planet gleams below, a majestic whorl of color and texture. All seems calm around you. With no satellites or space debris to dodge, you can just relax and enjoy the black emptiness of space. But looks can be deceiving. In reality, you've unknowingly jumped into an invisible mosh pit of electromagnetic mayhem "” the place in space where a supersonic "wind" of charged particles from the Sun crashes head-on into the...

PALO ALTO, Calif., Aug. 16 /PRNewswire/ -- It has long been known that the Earth's magnetic field provides a protective barrier for life on Earth. As energetic particles stream outward from the Sun in the form of the solar wind, they are deflected by a "force field" created by the Earth's magnetosphere. Now, a team of scientists from the Southwest Research Institute (SwRI) in San Antonio, Texas, the Lockheed Martin (NYSE: LMT) Space Systems Company Advanced Technology Center (ATC) in Palo...

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

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...
