After trapping a positron for the first time, physicists plan to use the resulting data to look for answers to one of ...

For the first time, Northwestern University physicists have coaxed a single positron—the antimatter counterpart of an ...

Physicists trap and cool down positron for months to measure its 'magnetic moment' with extraordinary precision.

You can’t hold antimatter in your hand or even in a regular laboratory apparatus. As soon as antimatter meets matter, the two ...

Introduction: What is antimatter?Antimatter has appeared here and there, such as in Part 5 where it was mentioned that ...

Getting places in space quickly has been the goal of propulsion research for a long time. Rockets, our most common means of doing so, are great for providing lots of force but are extraordinarily ...

Most atoms are made from positively charged protons, neutral neutrons and negatively charged electrons. Positronium is an exotic atom composed of a single negative electron and a positively charged ...

In experiments at the Brookhaven National Lab in the US, an international team of physicists has detected the heaviest "anti-nuclei" ever seen. The tiny, short-lived objects are composed of exotic ...

Something is leaking out of our galaxy — and it's antimatter. According to a paper published in Astronomy & Astrophysics in July 2026, gamma-ray signals detected outside the Milky Way suggest that ...

Northwestern University physicists held one positron, the antimatter twin of the electron, in a cold vacuum trap for months, ...
