Is Venus Volcanically Active?

Caption

This is an artist's impression of an active volcano on Venus. Results from a long-term study of Venus find evidence of a clear injection of sulfur dioxide into its upper atmosphere. One possible interpretation is that volcanic activity increased the sulfur dioxide component of the upper atmosphere, although an alternative is that a change in atmospheric circulation dredged up the gas.
