In August 2025, the global network of gravitational-wave observatories operated by the LIGO-Virgo-KAGRA (LVK) Collaboration released a huge new logbook of cosmic collisions – its fourth Gravitational-Wave Transient Catalog (GWTC-4.0) [1-6]. These gravitational waves, or ripples in spacetime, are created when the most extreme objects in the Universe, black holes and neutron stars, crash into…

Astronomers have developed a computer simulation to explore, in unprecedented detail, magnetism and turbulence in the interstellar medium (ISM)—the vast ocean of gas and charged particles that lies between stars in the Milky Way galaxy.

Turbulence is a ubiquitous phenomenon, which all of us have witnessed. The swirly movement of mixing milk in a coffee cup is the same in principle as…
