Canadian scientists observe hyperfine spectrum of antimatter hydrogen Posted: August 3, 2017

A Canadian-led investigation has opened a new chapter in antimatter research. In a study published today in Nature, the ALPHA Collaboration, which includes 50 physicists from 17 institutions, reports the first detailed observation of spectral lines from an antimatter atom, essentially the atomic finger print of the simplest form of antimatter. Antimatter does not exist in our universe and is instantly anhiliated when it comes into contact with regular matter, so experiments on antimatter must be conducted in magnetic bottles which keep the antimatter from touching anything in our world. The antihydrogen atoms are probed with microwaves to obtain a spectrum. Read more at Phys Org News.
