Abstract

The road to Damascus The Cassini flyby of 14 July 2005 revealed plumes of jets of water vapour and ice emanating from near the south pole of Saturn's icy moon Enceladus. This region is anomalously warm, with the highest temperatures associated with four 'tiger stripe' surface fractures on the moon's surface, colourfully named Alexandria, Cairo, Baghdad and Damascus. Joseph Spitale and Carolyn Porco have now applied triangulation techniques to Cassini images in order to obtain accurate bearings on the sources of the most prominent jets, and they find that they emanate from the tiger stripes, with the strongest sources situated on Baghdad and Damascus.
