The surface of Venus is littered with thousands of volcanoes, some of which may still be active until today. A fresh look at 30-year-old radar images captured by the Magellan spacecraft revealed new lava flows on Venus, suggesting that the planet was volcanically active between 1990 to 1992. NASA’s Magellan mission arrived at Venus in 1990 and became the first spacecraft to image the entire surface of the planet before plunging into the Venusian atmosphere on October 12, 1994.

Since its dramatic ending, no other spacecraft has been dedicated to exploring Venus. Although the radar images captured by Magellan are more than three decades old, scientists have developed new instruments to probe at the data and weave new discoveries about the hellish planet. Thirty-two year old Davide Sulcanese, a graduate student at the Università d’Annunzio in Italy and lead author of a new on Venus’ volcanism, jokes that the radar images examined by him and his team are of his exact age.

“This is very old data but with the new technology, we can still make it very useful even for new discoveries,” Sulcanese told Gizmodo. The team poured over two sets of Magellan radar data obtained in 1990 and 1992 to look for evidence of volcanic activity. In the images, team members found surface changes in two areas, the western flank of Sif Mons, a volcano on Venus, and in western Niobe Planitia, a large volcanic lowland province on the planet.

Scientists have previously found volcanic-related fe.
