Nature Astronomy, Published online: 27 November 2023; doi:10.1038/s41550-023-02140-4 The reported optical properties of organic hazes produced in water-rich exoplanet atmospheres differ from those in nitrogen-rich atmospheres. Such differences have a detectable effect on the spectra, impacting interpretation of JWST observations.

Nature Astronomy, Published online: 27 November 2023; doi:10.1038/s41550-023-02128-0 The observation by the IceCube Neutrino Observatory of high-energy neutrinos from the Galactic plane indicates that the Milky Way is deficient in neutrinos, most probably because it has not hosted an active

Nature Astronomy, Published online: 23 November 2023; doi:10.1038/s41550-023-02125-3 This work identifies a period structure in the radio emission of magnetars that can be observed in all classes of radio-emitting rotating neutron stars, regardless of their evolutionary history, their power source

Nature Astronomy, Published online: 23 November 2023; doi:10.1038/s41550-023-02119-1 Synchrotron and inverse-Compton emission provide evidence for a reverse-shock origin of the high-energy emission from a gamma-ray burst, GRB 180720B. The polarization of the optical emission originating from the reverse shock suggests
