The launch of ChatGPT late last year has school teachers, conference organizers, Google and others worried, for different reasons. Where should we draw the line when it comes to artificial intelligence?

A device combining a pulsed laser system with an Orbitrap mass analyser is well-suited for in situ exploration of prime astrobiological targets, such as Enceladus. Here a prototype of this instrument that is optimized for spaceflight applications demonstrates that this device could be used to characterize chemical biosignatures in future missions.

Analysis of a large galaxy sample shows that black hole activity is greater in galaxies in which the stellar and gas kinematics are misaligned. This observation suggests that the misalignment, driven by external gas accretion, fuels the central supermassive black holes.

A few missing photons in Fermi Gamma-ray Space Telescope observations lead to robust neutron star mass measurements in eclipsing millisecond pulsar binaries, ruling out an ultra-massive pulsar in the original Black Widow system.

Using JWST, the molecules seen in planetary atmospheres can be traced back to their cold origins in ices formed in dense interstellar clouds, before the onset of star formation, revealing that chemical diversity and complexity is achieved early.

A miniaturized instrument comprising a pulsed UV laser system and an Orbitrap analyser enables the characterization of the organic content and chemical composition of planetary materials, supporting the science objectives of future planetary missions.

Combined analysis of Chang’e-3 in situ measurements and Chang’e-5 laboratory samples, with an updated chronology from Chang’e-5 data, reconstructed the relation between age and composition of young lunar mare basalts. Results indicate persistent volcanism 2 Gyr ago, indicative of the presence of a heat source at the time.

A planetary origin model that forms exoplanets from a narrow ring of silicate material at a stellocentric distance of 1 au is able to explain the physical properties of super-Earths and reproduce the ‘peas in a pod’ pattern of uniformity within planetary architecture.
