Huge magnetic loops extending tens of thousands of km into space trapping hot gases inside them. We have seen such loop systems develop into extremely complex so-called 'active regions' where loops clash and twist like elastic bands before some kind of break down results in the ejection of clouds or streams of particles into space. The images show CDS' unique ability to map such regions. The coolest gases (20,000 degrees) are shown in the top left image, and the hottest (2 million degrees) in the bottom right. The edge of the Sun is seen on the left of each image and different gases show different loops giving a spectacular display above the surface of the Sun.
