My first week at CERN I went to a lecture on particle physics education where they explained that the high schoolers will struggle with the idea that particles can be emitted before they are absorbed.
And all the physicists nodded as if they had never before realised that was a difficult thought.

We're happy to join ISC and other fellow affiliated bodies in standing up for global climate-change research.
Space research is key for understanding how our planet is changing, so reductions in funding will have lasting impacts on decision-making, including adaptation and mitigation strategies.

There he had the chance to help strengthen connections between China and the global space community, and to catch up with friends of COSPAR.
