CERN highlights in 2025

From performing detailed studies of the Higgs boson to demonstrating the first antimatter quantum bit and converting lead nuclei into gold nuclei, this year CERN further expanded our knowledge of the world of particles.

In 2025, the Large Hadron Collider (LHC) delivered a record amount of data and collided oxygen and neon ions for the first time. Preparation for future accelerators also reached crucial milestones.

Beyond fundamental research, CERN strengthened its impact by sharing more innovations with society and welcoming new countries into its community of Member and Associate Member States.

As the year draws to a close, we look forward to 2026, when we will continue to explore beyond the horizon of knowledge. For now, why not take a look back at some of CERN’s highlights in 2025?
