Astronomers Discover Solar Wind Energy Source
2013-03-08 12:36:32

Using data from an aging NASA spacecraft, researchers have found signs of an energy source in the solar wind that has caught the attention of fusion researchers. NASA will be able to test the theory later this decade when it sends a new probe into the sun for a closer look.

Using Black Hole Disks And Jets To Explore The Limits Of Spacetime
2013-02-22 10:37:51

Black holes are voracious monsters at the center of galaxies that shape the growth and death of the stars around them with their tremendous gravitational pull and explosive ejections of energy. Now, researchers are using them as a tool to probe the limits of spacetime.

Understanding The Magnetosphere Better Than Ever With Help From THEMIS
2013-02-20 10:47:18

On Earth, scientists can observe weather patterns, and more importantly can predict them, through the use of tens of thousands of weather observatories scattered around the globe.

Tropical Cyclone 15S Forms In The Southern Indian Ocean Seen by NASA
2013-02-12 10:21:43

The fifteenth tropical cyclone of the Southern Indian Ocean season strengthened into a tropical storm today, Feb. 11, and NASA's Aqua satellite passed overhead hours after it reached tropical storm strength.

NASA Constructs Lobster Eye Imager

To study a poorly understood phenomenon known as charge exchange, NASA scientists teamed up to build NASA's first wide-field-of-view soft X-ray camera using "lobster eye" technology.

New Theory Of ENAs At Edge Of Solar System Checks Out With Data
2013-02-06 11:58:06

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
2013-01-21 15:01:22

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.

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...

Microquasar -- Microquasars are smaller cousins of quasars. They are named after quasars, as they have some common characteristics: strong and variable radio emission often seen as radio jets, and an accretion disk surrounding a black hole. In quasars, the black hole is supermassive (millions of solar masses) as in microquasars, the black hole mass is a few solar masses. In microquasars, the accreted mass comes from a normal star and the accretion disk is very luminous in optical regions...

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...

Van Allen Radiation Belt -- The Van Allen radiation belt is a torus of energetic charged particles around Earth, trapped by Earth's magnetic field. The presence of a radiation belt had been theorized prior to the Space Age and the belt's presence was confirmed by the Explorer I on January 31, 1958 and Explorer III missions, under Doctor James Van Allen. The trapped radiation was first mapped out by Explorer IV and Pioneer III. Qualitatively, it is useful to view this belt as consisting...

Solar Wind -- Solar wind, a stream of particles (mostly high-energy protons ~ 500 Kev) that is continually ejected from the surface of the Sun. The composition of this plasma is identical to the Sun's corona, 73% hydrogen and 25% helium with the remainder as trace impurities, and is ionized. Near Earth, the velocity of the solar wind varies from 200km/s-889km/s. The average is 450 km/s. Approximately 3000 tons of material is lost from the Sun every hour as solar wind. Since solar...
