Colour-coded topographic map of the surface of Venus,compiled from radar data recorded by the Pioneer-Venus spacecraft. The smooth circle at top marks the north pole,an area not mapped by the spacecraft. Most of the planet's surface is covered by relatively smooth plains,coloured blue in this image. Two large highland regions are visible (yellow),Ishtar Terra (upper left) and Aphrodite Terra (lower right). Ishtar Terra is a "continent" about the size of Australia,containing the Maxwell Montes (red),the highest mountains on Venus | |
