Nature Astronomy, Published online: 27 May 2024; doi:10.1038/s41550-024-02275-y Although ongoing volcanic activity on Venus has been hypothesized, directly detecting active lava flows is challenging. Now, an analysis of Magellan radar images of Venus acquired at different times provides indications of
