Latest Solar wind Stories
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.
Media representatives are cordially invited to a briefing on the occasion of ten years of scientific discoveries by ESAâ€™s Cluster mission.
Imagine floating 35,000 miles above the sunny side of Earth.
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.
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 American Geophysical Union has selected a research paper detailing observations of Mercuryâ€™s magnetosphere during the probeâ€™s third flyby as a â€œResearch Highlightâ€ in todayâ€™s issue of Eos, the AGUâ€™s weekly online and print newspaper.
ESAâ€™s pioneering Cluster mission is celebrating its 10th anniversary.
The first Europlanet prize for excellence in public engagement with planetary science has been awarded to Dr Jean Lilensten of the Laboratoire de PlanÃ©tologie de Grenoble.
NASA's plucky Voyager 2 spacecraft hit a long-haul operations milestone June 28 -- operating continuously for 12,000 days.
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."
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 -- 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...
