Nature Astronomy, Published online: 07 December 2023; doi:10.1038/s41550-023-02148-w A reanalysis of Kepler and Hubble data with Bayesian inference and a photodynamical model shows that the two exomoon candidates around Kepler-1625 b and Kepler-1708 b have a substantially lower probability to

Nature Astronomy, Published online: 05 December 2023; doi:10.1038/s41550-023-02136-0 Periodic sub-structure in radio emission from magnetars provides an observational link not only between magnetars and fast radio bursts, but across all classes of radio-emitting rotating neutron stars. The correlation between sub-structure

Nature Astronomy, Published online: 27 November 2023; doi:10.1038/s41550-023-02141-3 The optical properties of the organic hazes that form in water-rich exoplanet atmospheres differ from those that form in nitrogen-rich atmospheres. This difference in optical properties can have an observable effect on
