A Twisted Solar Eruptive Prominence

Explanation: Ten Earth s could easily fit in the “claw” of this seemingly solar monster. The monster, though, visible on the lower left, is a huge eruptive prominence seen moving out from our Sun . The above dramatic image taken early in the year 2000 by the Sun-orbiting SOHO satellite . This large prominence, though, is significant not only for its size, but its shape. The twisted figure eight shape indicates that a complex magnetic field threads through the emerging solar particles . Differential rotation inside the Sun might help account for the surface explosion . Although large prominence s and energetic Coronal Mass Ejection s (CMEs) are relatively rare, they are occurred more frequently near Solar Maximum , the time of peak sunspot and solar activity in the eleven-year solar cycle .
