Mysterious Math Of The Solar Wind Deciphered By NASA
2013-02-22 14:27:36

Many areas of scientific research -- Earth's weather, ocean currents, the outpouring of magnetic energy from the sun -- require mapping out the large scale features of a complex system and its intricate details simultaneously.

Cassini Catches Solar Wind, Helps NASA Study Particle Acceleration
2013-02-20 14:23:12

As it floats around the planet Saturn, the Cassini spacecraft recently got a front row seat to what NASA astronomers are calling an “unusual strong blast of solar wind.” Shortly after this “wind” blew by, Cassini began detecting particles which had been accelerated to ultra-high energies.

Cassini Records Possible Supernova Shockwave On Saturn

For the first time, scientists working with the Cassini spacecraft have detected subatomic particles accelerated to ultra-high energies in a blast of solar wind around Saturn, hinting at the possibility that the ringed planet may have experienced the aftermath of a supernova.

New Theory Of ENAs At Edge Of Solar System Checks Out With Data

A new theory describes a so-called Retention Model that may help explain unusual data collected form the edge of our Solar System.

Venus Caught Looking Like A Comet

At the very edges of the Earth’s atmosphere, where the Earth’s magnetic field begins, solar radiation strips electrons from the tenuous gas that is slowly leaking into space.

Auroras Exist Elsewhere Besides Earth, Say Planetary Scientists

Every year, eager sky watchers travel to the northern reaches of the Earth to catch a glimpse of the northern lights. This spectacle of color in the atmosphere – the Aurora Borealis and its companion to the south, the Aurora Australis – arises as the solar wind interacts with our atmosphere.

NASA Cluster Mission Sheds Light On Mysteries Of Solar Winds
2013-01-09 14:42:24

The European Space Agency’s (ESA) Cluster Mission has provided new insights into the mysteries of solar wind, showing for the first time how turbulence within solar wind can create a warming effect as the charged particles travel away from the sun.

Solar Winds May Be Warmed By Turbulent Plasma
2012-12-19 10:43:11

Scientists have zoomed in on solar wind to reveal the finest detail yet using the ESA's Cluster quartet of satellites as a space plasma microscope. They found tiny turbulent plasma swirls that could play a big role in heating the winds.

Solar Wind Storms Earth, Enhances Northern Lights

NASA said on Monday that our planet has entered a stream of high-speed solar wind that "escaped" through a coronal hole on the Sun.

Six Minutes In The Life Of The Sun For NASA's EUNIS Mission
2012-12-12 09:12:37

In December, a NASA mission to study the sun will make its third launch into space for a six-minute flight to gather information about the way material roils through the sun's atmosphere, sometimes causing eruptions and ejections that travel as far as Earth.

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...

upstander
  • A person who stands up for something, as contrasted to a bystander who remains inactive.
  • One of the upright handlebars on a traditional Inuit sled.
The word 'upstander' in the first sense here is a play on the word 'bystander' and the idea of 'standing up' for something.
