Scientists who have been monitoring the European Space Agency's Venus Express probe for the last six years might have found evidence of active volcanoes on the second planet from the Sun.

Data sent back by the unmanned probe has shown large changes in the sulphur dioxide content of the planet’s atmosphere, and one intriguing possible explanation is volcanic eruptions.

A new report from the ESA says: "The thick atmosphere of Venus contains over a million times as much sulphur dioxide as Earth’s, where almost all of the pungent, toxic gas is generated by volcanic activity.
