Supernovae keep galaxies churning A new study led by Fan Yi Meng from Tsinghua University provides the first comprehensive census of superbubbles in the Andromeda Galaxy, revealing that clustered supernova feedback is sufficient to sustain galactic-scale turbulence. This finding helps to explain why galaxies remain active over billions of years, with turbulence playing a crucial role in regulating star formation rates. The research, published in Nature Astronomy, highlights the energy balance between supernovae and the turbulence they create.Neutrinos may dictate stellar explosions A paper from Mariam Gogilashvili and Irene Tambora at the Niels Bohr Institute ex...
