At CERN, we probe the fundamental structure of particles that make up everything around us. We do so using the world's largest and most complex scientific instruments.

Set up in late 2005, ALPHA makes, captures and studies atoms of antihydrogen and compares these with hydrogen atoms.
The result is a milestone in the study of the properties and behaviour of antimatter
The measurements are consistent with predictions for “normal” matter and pave the way for future precision studies
The ALPHA-g and GBAR experiments have received their first beams of antiprotons
The ALPHA collaboration has observed a new electronic transition in the antihydrogen atom
The ALPHA experiment at CERN has measured a light-induced transition in antihydrogen with unprecedented precision
The ALPHA experiment at CERN’s Antiproton Decelerator reports the first observation of the hyperfine structure of antihydrogen
The ALPHA collaboration celebrate this week after twenty years of work resulted in them seeing, for the first time, antimatter's light spectrum
In a Nature paper, the ALPHA collaboration reports the first ever measurement on the optical spectrum of an antimatter
ALPHA reports a measurement of the electric charge of antihydrogen atoms, finding it to be compatible with zero to eight decimal places
The ALPHA collaboration has published a paper describing the first direct analysis of how antimatter is affected by gravity
