The Electric Atmosphere: Plasma Is Next NASA Science Target
July 17, 2012 — Two giant donuts of this plasma surround Earth, trapped within a region known as the Van Allen Radiation Belts. The belts lie close to Earth, sandwiched between satellites in geostationary orbit ... > full story -
Sun's Coronal Mass Ejection Results in Aurora Show on Earth
July 16, 2012 — Over the July 14-15, 2012 weekend and through the early morning of July 16, Earth experienced what's called a geomagnetic storm, which happens when the magnetic bubble around Earth, the ... > full story -
Hidden Portals in Earth's Magnetic Field
July 3, 2012 — A favorite theme of science fiction is "the portal" -- an extraordinary opening in space or time that connects travelers to distant realms. A good portal is a shortcut, a guide, a door into the ... > full story -
New Light Shed on Explosive Solar Activity
July 2, 2012 — The first images of an upward surge of the sun's gases into quiescent coronal loops have been identified by an international team of scientists. The discovery is one more step towards understanding ... > full storyMore: -
New Solar Active Region Spitting out Flares
June 14, 2012 — An active region on the sun, numbered AR 1504, rotated into view over the left side of the sun on June 10, 2012. The region fired off two M-class flares and two coronal mass ejections (CMEs) on June ... > full story -
Spotting Ultrafine Loops in the Sun's Corona
June 12, 2012 — A key to understanding the dynamics of the sun and what causes the great solar explosions there relies on deciphering how material, heat and energy swirl across the sun's surface and rise into the ... > full story -
Highest-Energy Light from a Solar Flare Ever Detected
June 11, 2012 — During a powerful solar blast on March 7, NASA's Fermi Gamma-ray Space Telescope detected the highest-energy light ever associated with an eruption on the sun. The discovery heralds Fermi's new role ... > full story -
Northern Lights Process Like Untangling Twisted Strands of Spaghetti?
June 1, 2012 — Scientists have reached a milestone in describing how the northern lights work by way of a process called "magnetic reconnection." The process is best imagined as untangling twisted strands of ... > full story -
Catching Solar Particles Infiltrating Earth's Atmosphere
May 31, 2012 — On May 17, 2012, an M-class flare exploded from the sun. They caused a shower of particles to cascade down toward Earth's surface. The shower created what's called a ground level enhancement ... > full story -
Solar Storm Seen from Inside and Outside Earth's Magnetosphere
March 28, 2012 — For the first time, instrumentation aboard two NASA missions operating from complementary vantage points watched as a powerful solar storm spewed a two million-mile-per-hour stream of charged ... > full storyMore:
