    The March/April 2026 issue of the CERN Courier is out

    Most of the universe is void. Of the rest, most is invisible. Yet it weaves a sprawling cosmic web, lit at its nodes by clusters of galaxies.

  • ALPHA measures tiny energy gap in antimatter with improved precision

    ALPHA measures tiny energy gap in antimatter with improved precision

    Researchers at the ALPHA experiment have achieved a hundredfold improvement in their measurement of a feature of the antimatter counterpart of the hydrogen atom. The result, published today in Nature, allows a precise comparison of hydrogen and antihydrogen. In this study, the ALPHA Collaboration measured the ground-state hyperfine splitting of the antihydrogen atom, which comprises

  • Ready for Heatwaves

    As spring gives way to summer, we must stay prepared for whatever the season brings – especially when it comes to periods of intense heat. MeteoSwiss declares a heatwave when average temperatures exceed 25°C for at least three consecutive days. To help protect personnel during such events, CERN introduced its dedicated Heatwave Action Plan in 2023. This
