Lee Rannals for redOrbit.com - Your Universe Online Predicting solar flares still remains a hit-or-miss task for scientists, but new research may shed more light on helping to predict just when the events could occur. Researchers discovered a new method to predict solar flares more than a day before they occur, which could help provide advanced warnings to protect satellites, power grids and astronauts. As the sun transitions into "solar maximum" next year, more solar activity is...

[ Watch the Video: STEREO Captures Fastest CME to Date ] Lee Rannals for redOrbit.com - Your Universe Online NASA's STEREO spacecraft has observed the fastest coronal mass ejection (CME) ever seen on the Sun. The Solar TErrestrial RElations Observatory (STEREO) clocked the massive eruption traveling between 1,800 and 2,000 miles per second as it ejected from the sun. NASA said this was the fastest CME ever observed by STEREO, which launched back in 2006. "Between 1,800 and...

A light bulb-shaped eruption leaps from the Sun and blasts into space in this archival image from the ESA/NASA Solar and Heliospheric Observatory, SOHO. SOHO captured the scene on 27 February 2000, watching as a large filament rose from the Sun´s broiling atmosphere and evolved into the coronal mass ejection loop seen here. A coronal mass ejection — or CME — is a huge cloud of magnetised plasma ejected from the Sun´s atmosphere — the corona — and...

[ Video 1 ] | [ Video 2 ] redOrbit Staff & Wire Reports - Your Universe Online A telescope launched on board a NASA sounding rocket earlier this month has captured the highest-resolution images of the sun's corona, the US space agency announced on Friday. The 16-megapixel images of the million-degree atmosphere of the sun were captured in an extreme-ultraviolet wavelength of light by the High Resolution Coronal Images (Hi-C) telescope, according to the Harvard-Smithsonian Center...

Coronal Mass Ejection Unlikely To Reach Earth
2012-07-21 04:31:52

[ Watch the Video ] redOrbit Staff & Wire Reports - Your Universe Online A coronal mass ejection (CME) associated with a solar flare emitted early Thursday morning is unlikely to reach Earth, but it could affect one of the two Solar Terrestrial Relations Observatory (STEREO) satellites currently orbiting the sun, NASA officials posted on the agency's official website. According to the US space agency, the sun emitted a mid-level (M7.7) flare on July 19. The flare, which began at...

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...
