Images Of Extreme Solar Activity Provide Origins Of Powerful Space Storms
2012-07-02 09:58:45

Lawrence LeBlond for redOrbit.com - Your Universe Online An international team of scientists have for the first time captured and identified images of an upward surge of the Sun´s gases into quiescent coronal loops, a discovery that provides one more step in the understanding of the origins of extreme storms in outer space, which are known to wreak havoc on satellite systems and power grids here on Earth. University of Cambridge researchers worked with colleagues from the India and...

Incoming Coronal Mass Ejection Coming On June 16
2012-06-15 13:39:44

[ Watch the Video ] Lee Rannals for redOrbit.com The sun is a ferocious, hot mess, and this week it showed off through a coronal mass ejection just how messy it can get. An active region on the sun fired off two M-class flares and two coronal mass ejections (CMEs) this week. NASA said the first flare lasted for three hours, and peaked on June 13 at 9:17 a.m. EDT.  The CME associated with the flare traveled up at approximately 375 miles per second. The second flare peaked...

Ultrafine Loops In The Sun's Corona
2012-06-13 15:31:07

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 upper atmosphere, or corona. Tracking the constantly moving material requires state-of-the-art telescopes with the highest resolution possible. By combining images from NASA's Solar Dynamics Observatory (SDO) and a new generation telescope called the New Solar Telescope (NST) at Big Bear Solar...

Process Linked To Northern Lights Observed

A University of Iowa researcher wants you to visualize a plate of spaghetti when you think of the northern lights. That´s because Jack Scudder, UI professor of physics and astronomy, and his colleagues have reached a milestone in describing how the northern lights work by way of a process called “magnetic reconnection.” The details are contained in a paper published in the June 5 issue of the journal Physical Review Letters; however, the process is best imagined as...

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...
