Antimatter measured for the first time

Researchers at the CERN Laboratory in Geneva have taken the first spectroscopic measurements of antihydrogen, marking an important milestone in the analysis of antimatter atoms.

The researchers first trapped antihydrogen atoms using a sophisticated arrangement of magnetic fields. Then, by shining precisely-calibrated microwaves onto the antiatoms, they flipped their magnetic orientation, releaseing them from the magnetic trap. The antiatoms then combine with regular matter and annihilate, producing a distinctive spectroscopic pattern.
