Latest Solar wind Stories
Two NASA spacecraft -- Hubble and Cassini -- captured 360 degree views of Saturn’s northern lights, giving a glimpse as to how the ringed planet looks when bathed in the Sun’s charged particles.
GREENBELT, Md., Feb.
Data from NASA's Van Allen Probes mission has helped researchers resolve decades of scientific uncertainty over the origin of ultra-relativistic electrons in Earth's near space environment.
New research published in the journal Nature resolves decades of scientific controversy over the origin of the extremely energetic particles known as ultra-relativistic electrons in the Earth's near-space environment and is likely to influence our understanding of planetary magnetospheres throughout the universe.
NASA's newest solar observatory is showing the region located between the surface of the sun and its atmosphere is more violent than previously thought.
Comet ISON has sprouted wings, which may suggest the nucleus of ISON is breaking apart.
A research team has finally found that the source of the extreme heating in the Sun's atmoshpere can be traced to magnetic oscillations known as Alfven waves.
When NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) mission launches on Monday, it will be carrying an instrument designed to scan high above the Martian surface for patterns of electrons that could explain why the Red Planet is losing its atmosphere.
What did NASA researchers mean when they recently stated that they had detected “interstellar music” which provided strong evidence that Voyager 1 had left the magnetic bubble surrounding the sun and planets known as the heliosphere?
Scientists from Rensselaer Polytechnic Institute in New York have published new research which they claim definitively refutes existing theories as to how the biomolecules were able to form inside of asteroids.
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...
