Massive underground instrument finds final secret of our sun's fusion
E-Mail A hyper-sensitive instrument, deep underground in Italy, has finally succeeded at the nearly impossible task of detecting CNO neutrinos (tiny particles pointing to the presence of carbon, nitrogen and oxygen) from our sun's core. These little-known particles reveal the last missing detail of the fusion cycle powering our sun and other stars. In results published Nov. 26 in the journal Nature (and featured on the cover), investigators of the Borexino collaboration report the first detections of this rare type of neutrinos, called "ghost particles" because they pass through most matte...
