Latest Solar prominence Stories
redOrbit Staff & Wire Reports - Your Universe Online On Thursday, October 25, NASA's twin Solar Terrestrial Relations Observatory (STEREO) program celebrated its sixth anniversary orbiting the sun, the US space agency announced on Friday. The twin orbiting probes were launched on that date in 2006, and ultimately entered into similar but separate orbits around the sun. STEREO-A's orbit is slightly smaller and faster, while STEREO-B's is larger and slower, they said, and those subtle...
Watch the Video: Filament Eruption August 31, 2012 Lawrence LeBlond for redOrbit.com - Your Universe Online Scientists from NASA have discovered an enormous ‘solar whip’ on the surface of the Sun and have warned that radiation from the phenomenon is heading straight toward Earth, arriving on our doorstep sometime today. The stunning event was captured by NASA’s Solar Dynamics Observatory (SDO) and, according to a report from Mail Online’s Mark Prigg, video and images of the...
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 launched into interplanetary...
Sometimes you really can believe your eyes. That's what NASA's STEREO (Solar Terrestrial Relations Observatory) spacecraft are telling researchers about a controversial phenomenon on the sun known as the "solar tsunami."Years ago, when solar physicists first witnessed a towering wave of hot plasma racing along the sun's surface, they doubted their senses. The scale of the thing was staggering. It rose up higher than Earth itself and rippled out from a central point in a circular...

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...
Chromosphere -- The chromosphere (literally, "color sphere") is a thin layer of the Sun's atmosphere just above the photosphere, roughly 10,000 kilometers deep. The chromosphere is more visually transparent than the photosphere. The most common solar feature within the chromosphere are spicules, long thin fingers of luminous gas which appear like the blades of a huge field of fiery grass growing upwards from the photosphere below. Spicules rise to the top of the chromosphere and then sink...
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:
