Brett Smith for redOrbit.com - Your Universe Online Using observations from two different NASA spacecraft, scientists have shed new light on the process behind solar flares and eruptions: magnetic reconnection. Magnetic reconnection occurs when magnetic lines collide and break apart - snapping into new positions and releasing energy in the process. On the sun, magnetic reconnections can result in radiation and solar material being flung across the solar system. These reconnections also...

PALO ALTO, Calif., June 10, 2013 /PRNewswire/ -- On December 15-16, 2011, a Sun-grazing comet, designated Lovejoy (C/2011 W3), passed deep within the hot solar atmosphere - the corona - effectively probing a region that could never be visited by spacecraft because of the intense heat radiating from the nearby solar surface. In a paper published today in the journal Science, researchers from several institutions - including the Solar & Astrophysics Lab at the Lockheed Martin (NYSE: LMT)...

Comet -- A comet is a small body from the outer reaches of the solar system similar to an asteroid but composed of ice. Often described as "dirty snowballs," they are composed largely of carbon dioxide ice, methane ice, and water ice with a mixture of dust and small stony aggregates mixed in. Comets are thought to be small pieces of debris left over from the formation of the solar system, representing a sample of the original composition of the nebula that condensed to form the Sun and all...

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...
