  • The complex collisional history of shocked L chondrites is reconstructed by combining high-pressure mineralogy, geochemistry, geochronology and orbital data. The results show that those meteorites arrive on Earth from over three distinct asteroid families.

  • 2023 CX1 is the only L-chondrite-like asteroid analysed from space to ground. It catastrophically fragmented in the atmosphere, depositing 98% of its energy in one burst—an unusual, high-risk fragmentation mode with implications for planetary defence.

  • The main asteroid belt contains a surprising diversity of objects, ranging from primitive ice-rock mixtures to igneous rocks. The standard model used to explain this assumes the violent dynamical evolution of the giant-planet orbits. Here, this evolution is shown to lead to the insertion of primitive trans-Neptunian objects into the outer belt, implying that the observed diversity of the asteroid belt is not a direct reflection of the intrinsic compositional variation of the proto-planetary disk, but rather of dynamical evolution.

  • The abundance of Be and V isotopes in calcium–aluminium-rich inclusions (CAIs), the oldest solids in the Solar System, shows that CAIs were irradiated by a gradual flux of radiation from solar flares when the Sun was young and more energetic, for a short time (300 yr) and at close distance (≈0.1 au).
