Based on topographic data obtained by NASA’s Magellan spacecraft, this figure shows the volcanic peak Idunn Mons in the Imdr Regio area of Venus. The colored overlay shows the heat patterns derived from surface brightness data collected by VIRTIS aboard the European Space Agency’s Venus Express spacecraft. The brightness signals the composition of the minerals that have been changed due to lav...
