Tropical Storm Jebi developed on July 31 and NASA satellite data on Aug. 1 shows the storm filling up at least half of the South China Sea.
A supermassive black hole is believed to sit at the center of each large galaxy and a new technique designed to detect the dark abyss's spin could be the key to unraveling a galaxy's history.
Using observations from two different NASA spacecraft, scientists have shed new light on the process behind solar flares and eruptions: magnetic reconnection.
This weekend, many in the Southern Hemisphere will have the opportunity to witness the annual Eta Aquarids shower, as they reach their peak rate.
NASA's Cassini spacecraft has helped shed light on one way the bubble of charged particles around Saturn changes with the planet's seasons.
NASA's Aqua satellite captured an image of Cyclone Zane headed toward the northern Cape York Peninsula of Queensland where it is expected to make landfall by May 2 and cross into the Gulf of Carpentaria.
Analysis of data collected by NASA’s Wind spacecraft as it travelled through the front of the Earth’s magnetosphere has revealed a special type of magnetic pulsations called SLAMS.
These colorful displays are produced when electrically charged particles traveling from the Sun in the solar wind are channeled along Earth’s magnetic field lines and strike atoms high in the atmosphere.
NASA's MAVEN spacecraft is scheduled for launch later this year, and with it will launch an instrument designed to study Mars' magnetic field.
On March 17, 2013, MESSENGER successfully completed its year-long first extended mission in orbit about Mercury, building on the groundbreaking scientific results from its earlier primary mission.
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...
