PALO ALTO, Calif., June 17, 2013 /PRNewswire/ -- The Interface Region Imaging Spectrograph (IRIS) spacecraft is on track for a launch from Vandenberg Air Force Base in California on June 26. IRIS will fill a crucial gap in the ability of scientists to advance Sun-Earth connection studies by tracing the flow of energy and plasma through a dynamic interface region - the chromosphere and transition region - between the solar surface and the solar corona. "The entire IRIS team is...

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)...

NASA Prepares IRIS Satellite For Solar Observing Mission

April Flowers for redOrbit.com - Your Universe Online Scheduled to launch June 26, NASA´s newest scientific satellite will provide the most detailed look ever at the sun´s lower atmosphere, called the interface region. The interface region is located between the sun´s visible surface and upper atmosphere. This is where most of the sun´s ultraviolet emissions, which impact the near-Earth space environment and Earth´s climate, are generated. NASA´s new...

Magnetic Field Model Of Sun Explains Solar Activity Cycles
2013-05-23 08:32:58

April Flowers for redOrbit.com - Your Universe Online Since the 18th Century, scientists have been aware that the Sun oscillates between periods of high and low solar activity in an 11-year cycle. So far, though, they have been unable to fully explain how this cycle is generated. Understanding the Sun´s magnetic activity has become increasingly important as we rely more on our electronic devices. Changes in the magnetic field are responsible for “space weather”...

Corona -- The corona is the luminous "atmosphere" of the Sun extending millions of kilometers into space, most easily seen during a total solar eclipse. An interesting feature of the corona is the fact that it is much hotter than the visible "surface" of the Sun; the photosphere is approximately 6000°C compared to the corona at over one million °C. The corona is much less dense than the photosphere, however, and so produces less light. The exact mechanism by which the corona is...

Solar Prominence -- Solar prominences are large arch-shaped structures observable in the solar corona. These often have a twist and occasionally become unstable, ejecting plasma and magnetic flux out from the sun. The physics of solar prominence instability is believed to be governed by magnetic forces and magnetic helicity issues. It is thought that instability occurs when a magnetic flux tube becomes excessively twisted. ----- Click here to learn more on this topic from eLibrary:

Solar Flare -- A solar flare is a violent eruption that explodes from a star's photosphere with energies equivalent to tens of millions of hydrogen bombs. Solar flares from the Sun send out a streams of highly energetic solar wind that can present a radiation hazard to spacecraft outside of planetary magnetospheres and can disrupt radio signals on Earth. Solar flares were first observed on the Sun in 1859 by English astronomer Richard Carrington. They have also been observed to...

The Sun -- intensely hot, self-luminous body of gases at the center of the solar system. Its gravitational attraction maintains the planets, comets, and other bodies of the solar system in their orbits. The sun is actually a star of about medium size; it appears larger than the other stars because of its relative nearness to the earth. The earth's distance from the sun varies from 91,377,000 mi (147,053,000 km) at perihelion to 94,537,000 mi (152,138,000 km) at aphelion (see apsis). The...
