Battered Volcano

Rainbow colors reveal elevation changes as the Tharsis Tholus volcano rises from the surrounding terrain on Mars, seen in a newly released picture from the European Space Agency's Mars Express orbiter.

The volcano towers almost 5 miles (8 kilometers) and spreads more than 96 by 77 miles (155 by 125 kilometers) at its base. In addition to its deep, crater-like caldera—formed when the central magma chamber collapsed—the volcano suffered from collapses on its eastern and western flanks that created vertical cliffs several kilometres high.
