Antimatter is powerful stuff, but is it a genuine mirror image of matter? The coldest antiprotons ever made take us a step closer to finding out. The simplest antiatom, antihydrogen, is made of an antiproton and a positron, the electron’s antimatter counterpart. If it is a mirror image of hydrogen, it should emit an identical spectrum of light. The way to test this is to create ultra-cold antihydrogen,
