Volcanic Activity on Venus?
This image is an artistic interpretation of a possible volcano on Venus. In fact, from previous missions to the planet, Venus appears to be among the most geologically active planets in the solar system.
Venus Express is able to detect gaseous markers in the lower layers of the atmosphere and variations in its temperature, possible signs of volcanic activity. Local variations in atmospheric temperature and pressure may also indicate the presence of seismic activity.
We are unable to see the surface of Venus due to its dense atmosphere.
