Spicules pop up from the Sun

3 de agosto de 2010

Spicules pop up from the Sun constantly. These dynamics jets are smaller features of the Sun that are commonly ignored. However, with the detailed close-up that SDO can provide, we can see these much more clearly than ever before. Over a few hours observation of the northern pole area of the Sun in extreme ultraviolet light (Aug. 3, 2010), we can see a continual frenzy of these features. At any one time there are around 60,000 to 70,000 active spicules on the Sun; an individual spicule typically reaches 3000-10000 km altitude above the photosphere. A couple of them rise up ten to 20 higher than most of the others. Spicules are an integral part of the dynamic nature of the Sun.
