Nature Astronomy, Published online: 06 May 2024; doi:10.1038/s41550-024-02266-z Decametre radio observations are challenging due to the presence of the ionosphere. Here Groeneveld et al. present a strategy to correct for the ionosphere that allows them to make sharp decametre radio

Nature Astronomy, Published online: 30 April 2024; doi:10.1038/s41550-024-02231-w Phase-curve observations of the ‘hot Jupiter’ exoplanet WASP-43b, made at mid-infrared wavelengths using JWST, provide evidence that fast winds limit the formation of methane on the cooler, cloudy nightside of the planet.

Nature Astronomy, Published online: 30 April 2024; doi:10.1038/s41550-024-02230-x Phase-resolved mid-infrared observations from JWST of the hot gas giant WASP-43b detect a day–night difference of 659 ± 19 K. Comparison with climate models shows that the observations are compatible with cloudy skies, at least

Nature Astronomy, Published online: 29 April 2024; doi:10.1038/s41550-024-02253-4 Cassini tracking data yield a lower Love number for Titan than previous analysis. This result is compatible with a low-density internal ocean that might consist of a mix of water and ammonia.

Nature Astronomy, Published online: 19 April 2024; doi:10.1038/s41550-024-02239-2 Simulated close encounters between planetary systems and other stars reveal that outer giant planets on wide orbits tend to be ejected, with a fraction of them forming bound pairs. This scenario would
