Space, mountains, oceans: Science at the frontiers of exploration
On Saturday 11 July 2026, join us at CERN Science Gateway from 16h onwards for an evening celebrating curiosity and discovery. Fro...
The ALPHA Collaboration has increased the precision of its measurement of the ground-state hyperfine splitting of antihydrogen by two orders of magnitude.
What’s going on at the #LHC? 🤔
While the Large Hadron Collider mostly collides protons, once a year it collides heavy ions – such as lead nuclei – a key ingredient for recreating the extreme condi..
At CERN’s Large Hadron Collider, high-energy beams collide in our giant detectors, generating vast amounts of data. This data is visualized through event displays.
To create these displays, experi...
On 20 April 2026, another important milestone was reached for the High-Luminosity Large Hadron Collider (hashtag#HiLumiLHC), with the start of the electrical powering of the 95-metre-long test stan...
Christian Smorra explains how the BASE-STEP portable antiproton trap captures and stores antiprotons. On 24 March 2026, 92 antiprotons were transported around the CERN site in this trap loaded onto...
Today, in a world first, a team of scientists from the BASE experiment at CERN successfully transported a trap filled with antiprotons in a truck across the Laboratory’s main site. The team managed...
This document stores the 90" video produced to descrive the activity of the Electrical Engineering Group (EN-EL). This is one of the 11 videos that have been produced between 2024 and 2025 to promo...
In physics, waves and particles seem like complete opposites. And yet, at CERN, we could not explore the incredible world of elementary particles without a thorough understanding of wave physics. T...
Interview of Marta Bajko, Head of IT String project. Scientists at CERN have triggered the complex cooldown of a 95-m-long test stand that reproduces the underground configuration of innovative tec...
#HiLumiLHC? 🤔
Listen to Markus Zerlauth , Project Leader for the High-Luminosity LHC – the successor to CERN’s flagship accelerator – as he explains the next steps of the project and what it would..
The #WomenInScience day is just around the corner 💪

What is antimatter?
Why do matter and antimatter annihilate and what happens when they do?
How much antimatter can we make and what can we use it for?
All of this in the first episode of Antimatt...
