Galaxies in cosmic voids retain gas better and form stars for longer periods of time.

The study, led by the Institute of Astrophysics of Andalusia (IAA-CSIC), analyzes, with an unprecedented level of detail, how the cosmic environment influences the evolution of more than two hundred galaxies. The results suggest that galaxies located in cosmic voids better preserve their gas and maintain more active star formation, especially in their outer regions.
