An international team of astronomers was able to measure the radius of a black hole for the first time.

Hurricane Lane Punched In The Eye Seen By Nasa
2012-09-19 07:29:28

Powerful thunderstorms wrapped tightly around Hurricane Lane's center as it continued moving through the eastern Pacific Ocean.

Cluster Examines Thin Current Sheets In The Magnetosphere
2012-08-02 05:08:15

The Universe is filled with plasma, a charged gas consisting of ions and electrons. Thin sheets, or boundaries, with currents separate large plasma regions. These boundaries are where most of the exciting action in space happens.

Waves In The Magnetosphere's Thin Boundaries Looked At By Cluster
2012-08-01 16:08:16

Exploiting a favorable configuration of ESA's Cluster mission spacecraft, scientists have detected and characterized lower hybrid drift waves, a special kind of plasma waves that develop in thin boundaries both in space and in the laboratory.

Solar Winds Affect Earth's Magnetosphere
2012-08-01 13:04:29

Weather has always affected our lives, but we are increasingly reliant on technology that can be disrupted by space weather. Geomagnetic storms, which are major disturbances of the magnetosphere, cause high altitude flights to be rerouted, costing many thousands of dollars per flight; cause GPS errors of up to 151 feet; and affect the International Space Station and satellites.

Geotail Mission Celebrates 20th Anniversary

Twenty years ago, the United States relationship with Japan showed just how restored it was since the second world war, as the two countries' space agencies launched a joint mission together.

New Research Better Understands Lunar Swirls

A study of "lunar swirls" on the moon may eventually lead to new developments in engineering to help protect astronauts in space.

Engineers and scientists at the Lockheed Martin [NYSE: LMT] Space Systems Advanced Technology Center (ATC) have completed delivery of key hardware subsystems for NASA’s Magnetosphereic Multiscale mission (MMS).

ESA Finds High-Energy Particles Charged In Polar Cusps
2012-06-08 04:46:56

Data gathered by ESA's Cluster mission suggests that high-energy particles which fill cavities within the Earth's magnetic field are accelerated locally within the cusps themselves as they cross through areas characterized by different electric potential.

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...
