In our latest CERN news… cooling with laser light ✴️ By applying the technique of laser cooling to a sample of positronium, the AEgIS experiment at CERN has managed to reduce the temperature of a positronium sample from 380 to 170 kelvin for the first time ever. This is an experimental feat that will help pave the way for a whole new set of antimatter studies.

How can light be used to cool atoms and molecules? Lasers are known to burn things, fix eyes, and dance on powerpoint presentations. But they can also be used to cool objects to some of the coldest temperatures in the universe.
