Latest Van Allen radiation belt Stories
Scientists use innovative Radio Aurora Explorer satellite to discover conditions that cause disruptions in space-based communication and navigation signals.
They nicknamed it the "Little Balloon That Could".
About eight months before the NASA rover Curiosity touches down on Mars in August 2012, the mission's science measurements will begin much closer to Earth.
Satellites are big and cost a lot of money -- at least that's the impression a couple of University of Maryland-College Park students had when they applied for an internship to help construct a satellite instrument with scientists at the NASA Goddard Space Flight Center in Greenbelt, Md.
Cluster has spent a decade revealing previously hidden interactions between the Sun and Earth.
NASA's Juno spacecraft will be forging ahead into a treacherous environment at Jupiter with more radiation than any other place NASA has ever sent a spacecraft, except the sun.
The first Europlanet prize for excellence in public engagement with planetary science has been awarded to Dr Jean Lilensten of the Laboratoire de PlanÃ©tologie de Grenoble.
A lightning researcher at the University of Bath has discovered that during thunderstorms, giant natural particle accelerators can form 40 km above the surface of the Earth.
Killer electrons are highly energetic particles trapped in Earth's outer radiation belt, which extends from 12 000 km to 64 000 km above the planetâ€™s surface.
High-energy bursts of gamma rays typically occur far out in space, perhaps near black holes or other high-energy cosmic phenomena - so imagine scientists' surprise in the mid-1990s when they found these powerful gamma ray flashes happening right here on Earth, in the skies overhead.
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...
