  • Kepler-1625b-I and Kepler-1708b-I are the most noteworthy exomoon candidates to date. A new analysis of the available data comes to a different conclusion.

  • Binary neutron star mergers are complex to understand astrophysically. A small piece of the puzzle may now have been solved using a computationally intensive simulation to explain how short gamma-ray bursts can be launched by a magnetar engine.

  • The size distribution of solid grains in dense clouds is a key parameter to constrain in order to understand grain growth, which influences the nature and timescale of the formation of protoplanets. A JWST study has quantified the grain size distribution by modelling the spectral absorptions arising from ice components of grains before protostellar collapse.

  • A model investigating the build-up of the atmosphere of Venus shows that it could have originated from a vigorous phase akin to plate tectonics during the first billion years of its evolution.

  • Measurements of Jupiter’s gravity by the Juno mission have established that the winds extend 3,500 kilometres below the surface. Cylindrically oriented zonal flows provide the best match in a new model using gravity harmonics up to degree 40.

  • High-resolution observations using a network of ground-based radio dishes and one telescope in space have revealed filamentary structures in the source 3C279. These filaments may explain the origin of radio variability in blazar jets.

  • Giant impacts can hit Venus harder than Earth in the end stages of planetary formation, super-heating Venus’s core. Slow escape of that heat drives long-lived surface volcanic activity.

  • Physics-informed neural networks allow the construction of state-of-the-art models of magnetic fields in active regions on the Sun in real time, enabling rapid investigation of the source regions for space weather.

  • Recent detection of polarized thermal emission from dust grains in a high-redshift, rapidly star-forming galaxy can give us an insight into the formation and evolution of magnetic fields in large-scale structures of the early Universe.

  • A quasar has taken part in the gravitational lensing of a background galaxy into an Einstein ring, which enables a remarkable measurement of the host galaxy lensing mass.
