"Relatively young lava flows have been identified by the way they emit infrared radiation. The finding suggests the planet remains capable of volcanic eruptions," according to the ESA statement. One of the project's scientist says Venus today could have as much volcanic activity as earth, which has upward of 1,500 volcanoes that have erupted in past 10,000 years.
The discoveries were made by the ESA's Venus Express which has been orbiting the planet since 2006. The Visible and Infrared Thermal Imaging Spectrometer (VIRTIS) on board the Venus Express measured the brightness of rocks to determine "emissivity," which determines if volcanic activity is present.

On a related note, President Obama and assorted politicians travel to Florida next Thursday to flesh out the priorities for NASA outlined in February. The controversial plan scraps planned moon shots and NASA development of heavy lift booster rockets.
