Cluster Helps To Model The Mysterious Magnetosphere Of Earth
2014-05-09 03:10:38

ESA For many years, scientists have been striving to understand the constantly changing structure and behavior of the huge magnetic bubble that surrounds our planet. One approach – pioneered by Russian scientist Nikolai Tsyganenko - has been to develop models based on data sent back by spacecraft, such as ESA's Cluster quartet. As Earth sweeps around the Sun, it is constantly bombarded by energetic particles from solar storms and deep space. Fortunately, the planet generates a...

2014-03-19 05:25:02

[ Watch the Video: STEREO Captures Fastest CME to Date ] redOrbit Staff & Wire Reports - Your Universe Online Researchers have uncovered the origin and cause of an extreme space weather event that took place July 22, 2012 on the sun which generated the fastest solar wind speed ever recorded directly by a solar wind instrument. The formation of the powerful event showed remarkable features as a massive cloud of solar material erupted off the sun's right side, zooming out into...

Van Allen Probes Helping To Refine Space Weather Computer Models
2014-03-10 07:45:30

redOrbit Staff & Wire Reports - Your Universe Online Data from the Van Allen Probes has been combined with a high-powered computer model to help researchers test and improve the forecast model to determine how the two giant near-Earth radiation belts they orbit can affect technology in space, NASA officials reported on Friday. The Van Allen radiation belts, which are teeming with rapidly-moving particles and a space weather system that varies in response to incoming solar particles...

Space Weather Shielding Provided By Plasma Plumes
2014-03-07 05:41:48

April Flowers for redOrbit.com - Your Universe Online The magnetosphere, Earth's magnetic field, stretches from the core of the planet out into space. Here, the magnetosphere meets the solar wind, a stream of charged particles emitted by the sun. The magnetosphere, for the main part, acts to shield the Earth from this high-energy solar activity. When the Earth's magnetosphere comes into contact with the sun's magnetic field in a process called "magnetic reconnection," the Earth's...

Space Weather Around Venus Is Harsher Than That Around Earth

[ Watch the Video: What's Causing Crazy Weather On Venus? ] Lee Rannals for redOrbit.com - Your Universe Online According to a study published in the Journal of Geophysical Research, space weather around Venus is much harsher than what is experienced around Earth. Scientists have discovered that the space weather around Venus can have such large explosions that they are bigger than the entire planet. They also said that these giant explosions can happen multiple times per day....

Ribbon Discovery At Edge Of Solar System Points To Influences From The Galactic Magnetic Field
2014-02-13 14:44:15

Lee Rannals for redOrbit.com - Your Universe Online NASA’s Interstellar Boundary Explorer (IBEX) discovered an enigmatic “ribbon” of energetic particles at the edge of our Solar System and a new study says it may be just a glimpse into how vast the influence of the galactic magnetic field really is. The galactic magnetic field around our solar system’s giant bubble, known as the heliosphere, determines the orientation of the ribbon and the placement of energetic particles...

NASA Spacecraft Capture Stunning Views Of Saturn's Dancing Auroras

[ Watch the Video: Saturn Puts On Quite A Light Show ] Lee Rannals for redOrbit.com - Your Universe Online Two NASA spacecraft 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. Using the Hubble Space Telescope and Cassini, NASA collaborated along with international researchers to put together the footage of the Saturnian show. Hubble provided an ultraviolet wavelength view of the...

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...
