Solar coronal loops, TRACE image
Solar coronal loops. Coloured ultraviolet TRACE image of coronal loops on the Sun following a solar flare event observed in November 2000. The bases of the loops are the hottest areas (white). These areas raise the temperature of the solar corona (atmosphere) thousands of times above that of the Sun's surface (dark, lower frame). The loops comprise electrically charged gases (plasma) at millions of degrees Celsius. Gas is heated as it is ejected from the surface, and follows the path of magnetic field lines before crashing back down on the Sun's surface at over 100 kilometres per second. TRACE (Transition Region and Coronal Explorer) is a space observatory launched in 1998 to study the Sun at ultraviolet wavelengths.

Northern Corries at dawn
Northern Corries at dawn. View looking west just before sunrise across Coire an t-Sneachda (hollow area) to Coire Lochain. The ridge separating the two hollows is is the Fiacaill Ridge. The flat area at left is the Cairngorm plateau. A corrie or cirque is a semi-circular hollow with a steep headwall. They are a feature of local mountain glaciation. In the Quaternary, the hollows may have been wholly or partly filled by small glaciers or may have acted as the source area for larger valley glaciers. Photographed in the Cairngorms National Park, Scotland, in November.
