Nature Astronomy, Published online: 10 October 2024; doi:10.1038/s41550-024-02382-w The Milky Way contains an extremely long-lived stellar disk component that formed, according to this study, more than 13 billion years ago. Such longevity is due to the exceptionally quiescent dynamical history

Nature Astronomy, Published online: 07 October 2024; doi:10.1038/s41550-024-02371-z The Universe comprises clusters and voids of galaxies and has been shaped by gravity over 13 billion years. Hamiltonian Monte Carlo simulations constrained by observed positions and velocities of galaxies produce maps of the

Nature Astronomy, Published online: 04 October 2024; doi:10.1038/s41550-024-02385-7 JWST observations of outflows from four young stars reveal in each case a molecular wind with a central cavity surrounding a fast jet. These results point to disk winds driving accretion, with

Nature Astronomy, Published online: 27 September 2024; doi:10.1038/s41550-024-02381-x In hyperarid environments, life can obtain water through salts that draw moisture from the atmosphere. These salts, then, should be a focus of searches for life on Mars. The experiments performed by

Nature Astronomy, Published online: 27 September 2024; doi:10.1038/s41550-024-02373-x Serpentinization — the metamorphism of rocks involving large amounts of water — includes many different aspects linked to habitability and offers a more reliable indicator of habitable conditions in the Solar System

Nature Astronomy, Published online: 27 September 2024; doi:10.1038/s41550-024-02376-8 Beneath the superficial diversity and complexity of galaxy morphology in our local Universe, galaxies show underlying simplicity and have universally bimodal distributions of normalized specific angular momentum of stars, revealed by MaNGA
