Our Solar System provides the closest and most accessible laboratory for understanding how planets, moons, comets, and asteroids form, evolve, and interact. Edinburgh researchers investigate the composition and dynamics of Solar System bodies using spacecraft data, telescopic observations, laboratory experiments, and modelling. From the chemistry of comets to planetary interiors, surface processes, magnetism, and atmospheric dynamics, our work reveals how the Solar System came to be—and how it continues to change today. We contribute to major international missions and develop new instruments that push the boundaries of Solar System exploration. This article was published on 2025-12-15
