At the edge of the Sun.jpgAt the edge of the Sun64 visiteCaption NASA originale: "Dramatic prominences can sometimes be seen looming just beyond the edge of the Sun. A Solar Prominence is a cloud of solar gas held just above the surface by the Sun's magnetic field. The Earth would easily fit below the prominence on the left. A quiescent prominence typically lasts about a month and may erupt in a Coronal Mass Ejection (CME) expelling hot gas into the Solar System. Although very hot, prominences typically appear dark when viewed against the Sun, since they are slightly cooler than the surface. The above image - in false color - was taken on June 1st, 2003, from Stuttgart, Germany, with a simple amateur telescope and camera".

Sun-prom1743_eit_big.jpgAnother "Solar Prominence" from Soho77 visiteCaption NASA originale:"This large prominence is significant not only for its size, but also for its shape. The picture was taken early in the year 2000 by the Sun-orbiting SOHO satellite. Although large prominences and energetic Coronal Mass Ejections (CMEs) are relatively rare, they are occurred more frequently near Solar Maximum, such as the time of peak sunspot and solar activity in the 11 year solar cycle".
