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...

Scientists from Boston University's Center for Space Physics (CSP) announced August 13 that they have sub-visual evidence of the onset of a new cycle of solar-terrestrial activity. The key results being reported deal with the fact that recent auroral displays at high latitudes (ones visible to the naked eye) were accompanied by far less luminous glows in the atmosphere at lower latitudes. "It's exciting to see the return of aurora to mid-latitudes," Dr. Steve Smith said, referring...

The American Geophysical Union has selected a research paper detailing observations of Mercury's magnetosphere during the probe's third flyby as a "Research Highlight" in today's issue of Eos, the AGU's weekly online and print newspaper. "Observations of Kelvin-Helmholtz waves along the dusk-side boundary of Mercury's magnetosphere during MESSENGER's third flyby," by Scott Boardsen and coauthors, originally published in Geophysical Research Letters, is available online at...

ESA's pioneering Cluster mission is celebrating its 10th anniversary. During the past decade, Cluster's four satellites have provided extraordinary insights into the largely invisible interaction between the Sun and Earth. Cluster's four satellites, Rumba, Samba, Salsa, and Tango, fly in formation around Earth to provide a 3D picture of how the continuous "Ëœsolar wind' of charged particles or plasma from the Sun affects our near-Earth space environment and its protective...

Prize For Excellence In Public Engagement With Planetary Science The first Europlanet prize for excellence in public engagement with planetary science has been awarded to Dr Jean Lilensten of the Laboratoire de Plan©tologie de Grenoble. For more than 10 years, Dr Lilensten has worked to share the magic of planetary aurorae with school children and members of the public across Europe, using his "Ëœplaneterrella' experiment. Dr Thierry Fouchet, Outreach Coordinator for...

NASA's plucky Voyager 2 spacecraft hit a long-haul operations milestone June 28 -- operating continuously for 12,000 days. For nearly 33 years, the venerable spacecraft has been returning data about the giant outer planets, and the characteristics and interaction of solar wind between and beyond the planets. Among its many findings, Voyager 2 discovered Neptune's Great Dark Spot and its 450-meter-per-second (1,000-mph) winds. The two Voyager spacecraft have been the longest continuously...

For more than 25 years, our understanding of terrestrial space weather has been partly based on incorrect assumptions about how nitrogen, the most abundant gas in our atmosphere, reacts when it collides with electrons produced by energetic ultraviolet sunlight and "solar wind." New research published today, Tuesday 8 June, in IOP Publishing's Journal of Physics B: Atomic, Molecular and Optical Physics describes how scientists from NASA's Jet Propulsion Laboratory (JPL) at the California...

Solar physicists at the University of California, Berkeley, have captured for the first time the collision of a comet with the sun. Using instruments aboard NASA's twin STEREO spacecraft, four post-doctoral fellows at UC Berkeley's Space Sciences Laboratory were able to track the comet as it approached the sun and estimate an approximate time and place of impact. STEREO (Solar TErrestrial RElations Observatory), launched in 2006, consists of identical spacecraft orbiting the sun, one ahead of...

Scientists from the University of Leicester have used observations from NASA's STEREO and ACE satellites to come up with more accurate predictions of when blasts of solar wind will reach Earth, Venus and Mars.  Anthony Williams will present the results at the RAS National Astronomy Meeting in Glasgow on Wednesday April 14th. We have recently been experiencing an unusually quiet and long-lasting solar minimum, and solar storms caused by Coronal Mass Ejections have been scarce. ...

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...
