Finding meteorites is no easy task. Despite this, a team of scientists including Prof. Maria Schönbächler from ETH Zurich, were successful. Their secret? Going to Antarctica where they found several new meteorites, including a unique piece weighing 7.6 kilograms.

Nearly two years ago, the Hayabusa2 space probe returned samples from the asteroid Ryugu to Earth. Since then, international research teams - including members of ETH Zurich and the National Centre of Competence in Research (NCCR) PlanetS - have worked on analysing the valuable cargo. The results allow the scientists not only to reconstruct the history of Ryugu but also to shed light on the early development of the solar system.

A recent study published in Science brings new constraints on planet formation. It highlights the role of collisions in shaping planets and affecting their composition.
