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

Nature Astronomy, Published online: 22 May 2024; doi:10.1038/s41550-024-02276-x The near-infrared spectrometer onboard JWST has detected CO2 and CO ices on 56 and 29 trans-Neptunian objects, respectively, indicating two dominant compositional types among them. These compositional differences suggest varied formation regions
