Neurons superimposed on JWST deep field image of distant galaxies

Read the January issue!

In this issue, we look at solar wind, gamma-ray bursts, gravitational waves and more. Plus, see if you can spot something written by ChatGPT...

  • Orange sky behind an observatory

    The global climate crisis has prompted the astronomy community in recent years to assess, primarily, the impact of its activities upon climate change, and secondarily, the impact of climate change upon astronomy. Collectively, these articles demonstrate that the research community needs to take rapid action in order to limit the impact on the climate and create a sustainable future for astronomy.

  • Zwicky 18 is a compact blue dwarf galaxy in Ursa Major

    Dwarf galaxies — galaxies of mass less than roughly a billion solar masses — have emerged as key laboratories for testing a number of open questions in astrophysics. This living Collection brings together a series of short and long articles on the science of dwarf galaxies, their properties and their theoretical modelling and simulations to present the current state of knowledge of the field.

Nature Astronomy is a Transformative Journal; authors can publish using the traditional publishing route OR via immediate gold Open Access.

  • A state-of-the-art machine-learning method combs a 480-h-long dataset of 820 nearby stars from the SETI Breakthrough Listen project, reducing the number of interesting signals by two orders of magnitude. Further visual inspection identifies eight promising signals of interest from different stars that warrant further observations.

  • 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.

  • 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.
