Sun's Silver Secret Solved by Non-Equilibrium Physics

New non-equilibrium atomic-physics simulations on the Sun's silver content suggest the Sun actually harbors about 55% more silver than earlier spectral measurements, potentially solving the 'missing silver' puzzle by showing it was hidden in plain sight; the result narrows the gap with CI chondrite meteorites and was achieved on Sweden's Tetralith supercomputer, with plans to apply the method to other stars; the study appeared in Astronomy & Astrophysics in July 2026.

New Research Reveals Solar Flares Are Significantly Hotter Than Previously Believed

A new study reveals that during solar flares, ions are significantly hotter than electrons—about 6.5 times hotter—explaining long-standing spectral line broadening mysteries and impacting space weather understanding. This insight suggests that ions' higher temperatures, especially during the flare's early stages, play a crucial role in flare dynamics and observations.
