Fourteen possible antimatter stars (“antistars”) have been flagged up by astronomers searching for the origin of puzzling amounts of antihelium nuclei detected coming from deep space by the Alpha Magnetic Spectrometer ( AMS-02 ) on the International Space Station. The mystery of matter and antimatter.

This left physicists scratching their heads until the late 1990s when experiments in Japan and Canada began finding definitive evidence that a neutrino of one flavour can change into a neutrino of a different flavour – a process called neutrino oscillation. So how do sterile neutrinos fit into all of this?

For Cao, it was a wonderful surprise given it only took 55 days to get a definitive answer to the critically important theta-13 problem, the value of which turned out to be much larger than expected. The transformation rate was surprisingly large, allowing Wang to announce the discovery of a new type of neutrino oscillation.
