Latest Solar prominence Stories
A snaking, extended filament of solar material currently lies on the front of the sun -- some 1 million miles across from end to end.
A magnetic filament of solar material erupted on the sun in late September, breaking the quiet conditions in a spectacular fashion.
Scientists studying the solar atmosphere have spotted some fascinating moving features in the Sun's sky.
Thanks to an innovative new camera on board a sounding rocket, an international team of scientists has managed to capture pictures of the sun's outer atmosphere that are five times sharper than any previous images.
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.
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.
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.
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."
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:
