• Space is dominated by plasma, the most common state of matter in the cosmos. • Modeling plasma is tough: fluid dynamics, turbulence, and Maxwell’s equations all intertwine. • The study examines orthogonally magnetized Richtmyer‑Meshkov instability in a two‑fluid plasma. • Authors from University of Queensland used simulations to capture shock‑plasma interactions. • Findings reveal how magnetic fields alter instability growth and mixing rates. • Results published in Physical Review Fluids, advancing our understanding of astrophysical plasmas.
