Coronal Mass Ejection Captured By SOHO
2012-09-29 08:20:34

April Flowers for redOrbit.com - Your Universe Online At 10:23 pm EDT on September 27, 2012, NASA's Solar and Heliospheric Observatory (SOHO) captured an image of a particularly wide coronal mass ejection (CME) that erupted from the Sun. SOHO is an international collaborative effort between NASA and the European Space Agency (ESA) to study the Sun from its deep core to the outer corona. The SOHO spacecraft also studies the solar winds generated by solar events. The sun erupted in a...

Coronal Mass Ejections Linked To Sun's Interior
2012-09-25 04:30:27

April Flowers for redOrbit.com - Your Universe Online After forty long years of debates and theories and counter-theories, the community of solar physics scientists has still failed to come to a consensus about what causes the sun's powerful coronal mass ejections (CMEs). CMEs have profound "space weather" effects on land based power grids and satellites in near-Earth geospace. An international team of scientists explains the mysterious physical mechanisms behind the origin of CMEs in a...

Astronomers Look Long At Coronal Mass Ejections

Lee Rannals for redOrbit.com — Your Universe Online Astronomers reported in The Astrophysical Journal they have a better understanding of the temperatures of the coronal cavities in Coronal Mass Ejections (CMEs). Terry Kucera, a solar scientist at NASA's Goddard Space Flight Center in Greenbelt, Maryland, along with colleagues, set out to understand the structure of CMEs, even before they erupt. CMEs are eruptions that take place on the sun that can travel toward Earth and...

IDEA! Coronal Mass Ejection From The Sun
2012-08-28 14:51:12

Watch the Video: Lightbulb Shaped CME Lee Rannals for redOrbit.com - Your Universe Online The sun sent off another coronal mass ejection (CME) last week, but this time the plasma burst showed up in the form of a light bulb. The Solar and Heliospheric Observatory (SOHO) caught the CME light bulb with its Large Angle and Spectrometric Coronagraph (LASCO) C2 instrument. This instrument is able to take images of the solar corona by blocking the light coming directly from the Sun with...

April Flowers for redOrbit.com - Your Universe Online Understanding weather patterns here on Earth is a complicated process, with scientists teasing apart different kinds of atmospheric movements, such as the great jet streams that can move across a whole hemisphere versus more localized, intricate flows, to create a whole picture. Those same methods and processes are used to understand the flows of the space weather system that links the Sun and the Earth as the Sun shoots material out...

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...
