The view shows a 100-km-wide nova superposed on Yavine Corona, a 500-km-wide asymmetric feature at latitude 5 degrees S., longitude 248.5 degrees; looking northeast. Coronae are roughly circular, volcanic features believed to form over hot upwellings of magma within the Venusian mantle. Yavine corona contains 2 novae; nova are circular hills with star-shaped fractures. The view is a close-up of the southern nova showing its fractures to be grabens or fault bound depressions. Novae may represent an intermediate stage in coronae formation.
This is a three-dimensional perspective view of Venusian Terrains composed of reduced resolution left-looking synthetic-aperture radar images merged with altimetry data from the Magellan spacecraft.
