Venus appears to be more volcanically active than previously known, according to scientists whose new analysis of decades-old radar images has spotted evidence of eruptions at two additional sites on the surface of Earth’s inhospitable planetary neighbor.
“These findings significantly change our understanding of the degree to which Venus is volcanically active, suggesting it could be much more active than previously thought,“ said planetary scientist Davide Sulcanese of d’Annunzio University in Pescara, Italy, lead author of the study published this week in the journal Nature Astronomy.
“Regarding the flows in Niobe Planitia, the lava flows appear to originate near small shield volcanoes and extend towards the northeast, also following the direction of the slope,“ Mastrogiuseppe added. “Our study is the first to provide direct proof of lava flows formed during the Magellan mission period. By analyzing radar images from the Magellan spacecraft, we observed changes in surface morphology and radar data indicative of new lava flows,“ Sulcanese said.
“It provides insights into the planet’s thermal evolution, surface renewal processes and atmospheric interactions,“ Mitri said.
