Nature Astronomy, Published online: 22 January 2024; doi:10.1038/s41550-024-02193-z A series of pieces published in this issue highlights the breadth and depth of topics discussed in modern astrobiology, an exciting discipline that has come to the forefront of astronomy in recent

Nature Astronomy, Published online: 22 January 2024; doi:10.1038/s41550-023-02145-z Chemical disequilibrium is a known biosignature, and it is important to determine the conditions for its remote detection. A thermodynamical model coupled with atmospheric retrieval shows that a disequilibrium can be inferred

Nature Astronomy, Published online: 18 January 2024; doi:10.1038/s41550-023-02187-3 High-mass stars in the Milky Way often exist in systems of two or more stars, but how this multiplicity arises is not clear and so far there have been no unequivocal observations

Nature Astronomy, Published online: 18 January 2024; doi:10.1038/s41550-023-02179-3 A combination of JWST/NIRCam observations and magnetohydrodynamic simulations indicates that frequent mergers with close companions give rise to bursty star formation and hence the unexpectedly high Lyman-α emission detected from early galaxies.
